What does the Wise Business Fees Calculator actually compute?

This tool estimates the foreign exchange (FX) cost you pay when Wise Business converts money from one currency into another. You give it a currency pair and a monthly transfer volume, and it returns the FX fee you can expect to lose to conversion each month. Wise prices conversions on a transparent model: it starts from the mid-market rate (the rate you see on a search engine or financial data feed) and adds a stated conversion fee on top. For most pairs that fee lands roughly in the 0.3 to 0.7% range, which is the band this calculator works from. The output is not a quote from Wise itself. It is a planning figure you can use to compare the true cost of running multi-currency revenue through Wise versus other options a Delaware LLC commonly uses.

For a non-resident founder who formed a Delaware LLC, this matters because your revenue and your costs rarely sit in the same currency. You might invoice clients in euros, pay contractors in Indian rupees, and hold your operating balance in US dollars. Every time money crosses a currency boundary, a fee is taken, and over a year those fees add up to real money that never shows on a single invoice. The calculator turns an invisible drip into a number you can see. Once you can see it, you can decide whether Wise is the right rail for a given flow, whether you should batch conversions, or whether holding a balance in the target currency would save more than it costs. The goal here is to make the conversion cost legible before it quietly eats into your margin.

How should I read the currency pair input?

The currency pair is the heart of the estimate, because Wise does not charge one flat percentage across every currency. The fee depends on which currency you are converting from and which one you are converting into. A high-liquidity pair like USD to EUR sits near the low end of the band, while a thinner or more exotic pair carries a higher conversion fee. When you enter the pair, think in terms of the direction money actually moves. If your clients pay you in euros and you want to hold dollars, your source currency is EUR and your target is USD. If you keep funds in dollars and pay a supplier in British pounds, the source is USD and the target is GBP. Direction matters because the fee is attached to the conversion event, not to the account, and a round trip (convert out, then convert back) is charged twice.

A practical way to use the input is to model each real flow you have rather than a single blended pair. Most founders have two or three recurring conversions, and each deserves its own pass through the tool. Consider listing them out before you start:

• Incoming client revenue that needs to land as your operating currency.
• Outgoing contractor or supplier payments in their local currency.
• Periodic sweeps where you move a held balance into the currency you actually spend.

Run the calculator once for each line, then add the monthly figures together. That gives you a far more honest total than a single guess, because a cheap USD to EUR flow can be masking a pricier flow into a less common currency. If you only model your largest flow, you will understate the cost of the small ones that quietly recur every month.

How do I read the monthly volume input?

Monthly volume is the total amount you expect to convert through Wise in a given month for that pair. It is the base the fee percentage is applied to, so getting it roughly right matters more than getting it exact to the cent. Because Wise's fee is proportional, the cost scales linearly with volume: double the amount you convert and you double the fee, holding the pair constant. That linearity is useful, because it means you can reason about thresholds. If converting $10,000 a month costs you a certain amount, you already know what $20,000 or $5,000 would cost without re-running anything. The tool is doing simple proportional math on a transparent fee, not predicting future rates.

Be careful to use the amount actually converted, not your total revenue. If half your euro income stays in euros to pay euro expenses, only the half you convert to dollars belongs in the volume field for the EUR to USD line. Founders routinely overstate volume by entering gross turnover, which inflates the fee estimate and can push them toward a wrong decision. Equally, watch for seasonality. If you have a spike month where a large annual contract settles, model that month separately so the one-time conversion does not distort your steady-state planning. A clean approach is to estimate a normal month and a peak month, run both, and keep the two numbers side by side when you decide how to route money.

What does the output tell me, and what does it leave out?

The output is your estimated monthly Wise FX cost for the pair and volume you entered, presented alongside a comparison against other rails a Delaware LLC might use, such as Mercury, Payoneer, and a traditional bank wire. Read the headline number as the conversion fee you give up to move money across the currency line. The comparison is there so you are not judging Wise in a vacuum. A fee that looks large in isolation can still be the cheaper option once you see what a bank wire with a marked-up exchange rate and a flat wire charge would have cost on the same flow. The point of the side-by-side view is to anchor your decision in relative cost rather than an abstract percentage.

It is just as important to know what the figure does not capture. The estimate covers the FX conversion fee. It does not include every possible Wise charge, and it does not model the mid-market rate moving between the moment you plan and the moment you actually convert. Rates shift, so your real cost on conversion day may differ slightly from the planning figure even when the fee percentage is unchanged. The output also assumes a fee inside the typical band. If your specific pair sits outside that band, treat the number as a floor rather than a precise quote. Use the result to compare options and to size the problem, then confirm the exact charge inside your Wise account at the moment you convert.

A worked example: a EUR-invoicing founder holding USD

Imagine a non-resident founder running a Delaware LLC that sells software to European customers. Clients pay in euros, but the founder keeps the operating account in US dollars to pay a US tax preparer and US software subscriptions. Suppose $12,000 worth of euros comes in each month and all of it needs to become dollars. The founder enters EUR as the source, USD as the target, and a monthly volume equivalent to $12,000. At a conversion fee near the low end of the band, the tool would show a monthly FX cost in the low tens of dollars, and at the higher end of the band it would show a figure several times that. The spread between those two ends is exactly why reading the pair carefully matters, because a common pair like EUR to USD tends toward the cheaper side.

Then extend the example. The same founder also pays a contractor in Polish zloty, converting roughly $3,000 a month from the dollar balance. That is a second line: USD source, PLN target, $3,000 volume. The founder runs the tool again and adds the two monthly figures. The combined number is the real monthly FX overhead of the business, and annualizing it (multiply by twelve) often surprises founders who assumed the cost was trivial. With that annual figure in hand, the founder can weigh concrete moves: holding a euro balance to net euro income against euro costs, batching the zloty payments quarterly, or routing one flow through a different provider. None of those moves are obvious until the calculator makes the yearly drag visible.

What underlying rule is the calculator based on?

The calculation rests on Wise's mid-market-plus-fee model. Wise does not bake a hidden spread into the exchange rate the way many banks do. Instead it uses the mid-market rate as the starting point and charges a separate, disclosed conversion fee. The calculator mirrors that structure: it takes your volume, applies a conversion fee inside the typical band for the pair, and reports the result. Because the fee is a percentage of the converted amount, the math is proportional and the result moves in a straight line with volume. This is fundamentally different from a flat-fee model, where small conversions are punished and large ones are cheap per dollar. Under a percentage model, the cost per dollar stays the same whether you convert $500 or $50,000, so batching does not reduce the FX fee itself.

Understanding the rule changes how you act on the output. If the fee were flat, the right move would be to consolidate many small conversions into one large one to dilute the fixed cost. Under a percentage fee, that consolidation saves nothing on the conversion fee, though it can still reduce other per-transfer charges and administrative effort. The lever that actually moves a percentage-based FX cost is reducing how much you convert at all. Holding a balance in a currency you both earn and spend lets you net flows internally and convert only the surplus. The calculator helps you find that surplus, because once you see the monthly cost you can ask whether part of the volume could simply stay where it is.

How does this compare with Mercury, Payoneer, and bank wires?

The comparison block exists because Wise is one of several rails a Delaware LLC can use, and the right choice depends on the flow. Mercury, Wise, Relay, Lili, and Payoneer are all banking options non-resident founders reach for, and each handles currency differently. Some are strongest for holding and spending US dollars, while others shine on multi-currency conversion. A traditional bank wire is usually the costliest path for FX because the exchange rate is marked up and a flat wire fee is layered on top, which is brutal on small amounts and merely expensive on large ones. The comparison helps you avoid defaulting to a wire out of habit when a transparent percentage fee would have been cheaper.

Use the side-by-side numbers as a starting point for routing rather than a final verdict. A few patterns tend to hold:

• For frequent conversions on common pairs, a transparent percentage fee is often easier to predict.
• For large one-off transfers, a flat wire fee can be diluted but the rate markup usually still hurts.
• For flows where you earn and spend the same currency, the cheapest conversion is the one you avoid.

The comparison is about fit, not about crowning one provider. A founder may sensibly hold dollars in one account, convert euros through Wise, and reserve wires for the rare large settlement where speed outranks cost. The tool gives you the cost dimension so that routing decision is grounded in numbers.

What are the most common mistakes founders make with this estimate?

The frequent error is confusing revenue with converted volume. If you enter your entire euro turnover when only part of it is actually converted to dollars, the fee looks far worse than reality and you may abandon a rail that was serving you well. The mirror image is just as common: entering only your largest flow and ignoring the small recurring conversions that, added together, cost more than the headline flow. A second mistake is treating the output as a guaranteed quote. It is a planning estimate built on a typical fee band, and your exact charge on conversion day depends on the live fee for that pair and the mid-market rate at that moment. Anchoring a hard decision to the penny on a planning number invites disappointment.

A third mistake is forgetting that a round trip is charged on each leg. Founders sometimes convert dollars to euros to pay a euro invoice, then convert leftover euros back to dollars, and they only model one direction. Each conversion carries its own fee, so a there-and-back movement should be entered as two lines. Finally, people forget to annualize. A monthly figure that feels small can look very different once multiplied by twelve, and that yearly view is usually what justifies a structural change like holding a foreign balance. Run the tool per flow, sum the monthly results, multiply by twelve, and only then judge whether the cost warrants a different approach.

What edge cases should I watch for?

Several situations stretch the simple model. The first is an uncommon currency pair. The calculator works from a typical fee band, and a thinly traded pair can carry a conversion fee above that band, so treat the result for an exotic target currency as a floor and verify the live fee before you rely on it. The second is highly variable monthly volume. If your conversions swing wildly between months because of seasonal contracts or irregular client payments, a single average can mislead. Model a normal month and a peak month separately and keep both numbers. The third is a balance you intend to hold rather than convert. If you keep euros to pay euro costs, that portion should never enter the volume field, because it is not being converted at all.

Another edge case is timing-sensitive conversions. If you must convert on a specific date to settle an obligation, you cannot wait for a favorable rate, and the mid-market rate on that day is whatever it is. The fee percentage is stable, but the underlying rate is not, so a tight settlement window removes your flexibility even though the calculator's fee estimate stays valid. One more case worth flagging: do not confuse FX cost with account or tax obligations. This tool only models conversion fees. It says nothing about your Delaware franchise tax of $300 due June 1, your Certificate of Formation cost of $110, or your federal filing duties, all of which are separate matters with their own deadlines and their own consequences for getting them wrong.

How does FX cost fit alongside my Delaware LLC's fixed obligations?

FX fees are a variable cost that rises and falls with how much you convert, and they sit beside a set of fixed obligations that arrive whether or not you move any money. A Delaware LLC owes a flat franchise tax of $300 due June 1 each year, and missing that date triggers a $200 late penalty plus interest accruing at 1.5% per month, so the cost of forgetting is far larger than the tax itself. The Certificate of Formation that created the company cost $110. These are predictable line items you can put on a calendar. FX cost is different in character: it is paid continuously in small slices every time currency crosses a boundary, which is precisely why it hides so well and why putting a number on it is worthwhile.

Seeing both kinds of cost together helps you budget honestly. The fixed items are non-negotiable and time-bound, while the FX drag is something you can actually reduce through how you structure your money. A founder who maps the annual FX figure next to the franchise tax often realizes the conversion drag rivals or exceeds the tax, and that realization is what prompts smarter routing. It is also a reminder that an Employer Identification Number is free through the SS-4 process and arrives in roughly 8 to 10 business days, so not every cost of running the company is a fee. Knowing which costs are fixed, which are free, and which are variable and reducible is the foundation of sensible cash management, and this calculator owns the last category.

What federal filing duties sit outside this tool entirely?

This calculator is about banking and currency cost, but a non-resident founder should never let FX planning crowd out the federal filings that carry real teeth. A single-member Delaware LLC owned by a non-resident is generally treated as a disregarded entity that must file Form 5472 together with a pro forma Form 1120 each year to report transactions with its foreign owner. Missing or botching that filing can trigger a $25,000 penalty, which dwarfs any FX fee this tool will ever show you. The conversion fees modeled here are a matter of optimization, while the 5472 filing is a matter of compliance, and the two should be tracked on entirely separate lists so the smaller, more interesting optimization problem never eclipses the larger obligation.

On the lighter side of compliance, beneficial ownership reporting changed in 2025. Under the FinCEN interim final rule of March 26, 2025, US-formed entities such as a Delaware LLC are exempt from the BOI reporting requirement, which removes one item that earlier guidance had founders worried about. That is worth knowing so you do not waste effort on a filing that no longer applies to your structure. The takeaway is to keep three buckets clearly separated: the variable FX cost this tool helps you minimize, the fixed state obligations like the franchise tax, and the federal filings like Form 5472 whose penalties make them the items you check first. Optimize the conversion cost, but never at the expense of the filings that protect the company.

What should I do with the result once I have it?

Treat the number as the start of a decision, not the end of one. First, annualize it and any companion lines so you are looking at a yearly FX figure rather than a monthly slice that feels too small to act on. Second, compare that figure against the alternatives in the comparison block and against the simple option of holding a balance in a currency you both earn and spend. If a large share of your volume is converting a currency you also pay out, the cheapest improvement is usually to stop converting that slice and net it internally instead. The calculator's value is that it tells you whether the FX drag is big enough to justify changing how you route money, or small enough to leave alone and revisit later.

Concretely, a sensible workflow looks like this:

• Run each real flow separately and sum the monthly figures, then multiply by twelve.
• Hold the annual total next to your fixed costs so the FX drag has context.
• Decide whether to hold balances, batch transfers, or split flows across rails.
• Re-run the tool whenever your volume, currency mix, or provider changes.

Revisit the estimate at least once a year, because a growing business converts more and the FX cost grows with it. A flow that was negligible at $3,000 a month can become a meaningful line at $30,000 a month, and the proportional fee will track that growth exactly. By keeping the calculation current, you make sure the currency cost of your Delaware LLC stays a deliberate choice rather than a silent leak.
