The formula
Total cost = Outgoing fee + Intermediary deductions + Receiving fee + (Amount × FX margin ÷ 100)
Fees are modelled in sending-currency terms so the total is a single comparable number. The "estimated amount delivered" subtracts the full stack from your send amount — this is the number to give your beneficiary.
The effective cost rate (total cost ÷ amount) exposes the regressive nature of flat fees: identical fees consume 1.8% of a $5,000 wire but only 0.18% of a $50,000 wire. For small recurring payments, flat fees dominate; for large payments, the margin does.
How to use this calculator
- 1
Copy your bank’s outgoing wire fee
From the tariff sheet or your last statement — business accounts typically pay $25–$50.
- 2
Estimate intermediary deductions
$0 for same-currency wires between major banks; $20–$60 for cross-currency routes through correspondents.
- 3
Add the receiving fee
Ask your beneficiary what their bank charges for inbound international credits — commonly $5–$25.
- 4
Set the FX margin and read the total
Use your bank’s published margin or measure it with the FX Margin Calculator. The delivered amount line is your answer.
The four layers, ranked by typical impact
On converted business wires, the ranking is consistent: FX margin first (often 2–4% at retail banks), outgoing fee second, intermediary deductions third, receiving fee last. The ranking flips only for same-currency wires (margin = 0) or very small amounts where flat fees take over.
This ranking dictates negotiation strategy. Getting your bank to waive the $45 wire fee saves $45. Getting the margin from 3% to 1% on a $50,000 payment saves $1,000. Businesses consistently negotiate the wrong layer because it is the only one on the receipt.
When a wire is the wrong tool
International wires earn their cost on large, infrequent, document-heavy payments. They are poorly suited to frequent small payouts — contractor payments, refunds, marketplace disbursements — where per-payment flat costs compound brutally. For those flows, local-rail payout networks price per transaction at a fraction of wire economics.
The decision is quantitative: run your actual payment profile through this calculator and the Contractor Payment Calculator, and let the effective rates decide. KeyBS Pay supports both patterns — quote-based cross-border payments and payout rails — so the choice is routing, not re-platforming.
Common use cases
Invoice settlement planning
Compute the amount to send so the beneficiary receives the exact invoice value after all deductions.
Bank vs provider benchmarking
Model your bank’s full stack against a quote-based provider’s single disclosed fee for the same payment.
Fee audit
Reconcile last quarter’s wires: multiply the modelled cost by payment count and compare with what your P&L absorbed.
Payment sizing
Test whether consolidating four monthly $5,000 wires into one $20,000 wire meaningfully cuts your effective rate.

Frequently asked questions
How much does an international wire cost in total?
For a typical converted business wire at a traditional bank: $35–$50 outgoing, $20–$60 in intermediary deductions, $5–$25 receiving, plus a 2–4% FX margin. On $10,000 that is roughly $280–$530 all-in. Specialist providers on liquid corridors often halve that or better. Your route decides — model it above.
Who pays the intermediary bank fees?
Under the default SHA charging option, they are deducted from the principal mid-route — so effectively the beneficiary pays them by receiving less. Under OUR, the sender pays an upfront estimate. Agree the option with your counterparty before sending.
Why is the exchange rate margin not on my receipt?
Because it is embedded in the rate rather than charged as a fee. The receipt shows the rate applied, not the wholesale rate the bank obtained. The difference — your cost — requires an external reference rate to measure, which is exactly what the FX Margin Calculator does.
Are wire fees negotiable?
Yes, especially for businesses with volume. But negotiate the margin, not just the flat fee: on business-sized payments the margin is typically 5–20× the flat fee’s impact. Bring calculated effective rates to the conversation.
How long does an international wire take?
Route-dependent — commonly one to four business days for converted wires through correspondents, with compliance reviews able to extend that. Local-rail last-leg delivery, where available, shortens and stabilises timing.
What does KeyBS Pay charge instead?
Quote-based pricing from 1.5%, route-dependent, disclosed in full before approval — the quote commits the receive amount, so the layered-deduction problem this calculator models is eliminated on KeyBS Pay routes.
