How much does pre-funding cost? A working capital formula for cross-border payout teams
Price pre-funded payout balances in basis points: the balance formula, five cost lines, an illustrative worked example, and a sensitivity table to copy.
Pre-funding costs the return you give up on money parked in advance, plus FX revaluation on foreign balances, refill fees, account upkeep, and staff time. Size the balance as daily payout volume times coverage days, price those five lines for a year, and divide by annual volume. In this article's illustrative example, that comes to about 34 basis points.
Most teams know pre-funding is expensive. Few can say how expensive in a number they can put next to a provider's fee. This guide gives you that number, with every assumption visible so you can swap in your own.
Key takeaways
- Pre-funded balance = daily payout volume x coverage days, per currency.
- Five annual cost lines: cost of capital, FX allowance, refill fees, account maintenance, operations time.
- Express the total in basis points of payout volume so you can compare it with per-transaction fees.
- Coverage days drive the result. Cutting refill lead time is worth more than negotiating a wire fee.
- Funding at send time keeps destination-currency balances at zero, but you still plan when your dollars arrive.
Definition: Pre-funding means depositing money in advance, in the destination currency or with a payment provider, so payouts can be drawn from a balance that is already in place. The balance waiting to be spent is trapped capital: it is yours, but you cannot invest it or use it elsewhere.
Why do cross-border payouts require pre-funding at all?
Because the traditional model settles through balances held in each country. A bank or provider that pays out in pesos needs pesos on hand before the payout, and someone has to put them there.
That balance used to live in correspondent banks' nostro accounts. The network behind it has been shrinking: the BIS Committee on Payments and Market Infrastructures reported in August 2020 that the number of active correspondent banks worldwide fell 22% between 2011 and 2019 (BIS CPMI). Fewer correspondents means fewer, more concentrated places to park those balances.
Scale helps the banks that remain. A March 2026 Federal Reserve note points out that large international banks can manage liquidity better by aggregating many transactions and can maintain inventories of foreign currencies (Federal Reserve). A mid-size payout company does not have that scale, so it pays for the inventory itself. Nostro and vostro accounts explained covers the mechanics.
How big does a pre-funded balance need to be?
Big enough to cover payouts until the next refill lands, plus a safety buffer. Calculate it per currency.
Balance per currency = daily payout volume x coverage days
Coverage days add up three things:
- Refill lead time. Calendar days from deciding to top up until the money is usable in the destination account. An international wire with a weekend in the middle can take a week.
- Payout cycle gap. If you pay in weekly batches, you need the full batch on hand on payout day, which adds up to seven days of volume.
- Safety buffer. Days of extra volume for spikes, holidays, and a refill that arrives late.
A team with a 5-day refill lead time, weekly batches, and a 5-day buffer is covering about 17 days of volume in every currency it pays out. Most teams have never written that number down.
What are the five cost lines of pre-funding?
Five lines, priced for a year. The first two scale with the balance, the last three with the number of currencies and refills.
| Cost line | Formula | What drives it |
|---|---|---|
| 1. Cost of capital | Balance x your annual cost of capital | Coverage days, interest rates |
| 2. FX allowance | Non-dollar balance x expected annual adverse move | Currency volatility, size of foreign balances |
| 3. Refill fees | Refills per year x fee per refill | Number of currencies, refill frequency |
| 4. Account maintenance | Accounts x annual fees and compliance upkeep | Number of countries |
| 5. Operations time | Hours per week x 52 x loaded hourly cost | Manual forecasting, top-ups, reconciliation |
Total annual pre-funding cost = lines 1 to 5
Cost in basis points = total annual cost / annual payout volume x 10,000
Two notes on the inputs. Cost of capital is whatever the money would otherwise earn or save you: a Treasury bill yield, a credit line rate, or your internal hurdle rate. The FX allowance is a planning number, not a forecast. Pick a figure your treasury team will defend, such as a plausible one-year adverse move for each currency.
Leave the conversion spread out. You pay it in every model, because dollars have to become local currency at some point. Who carries FX risk in a stablecoin payout separates conversion cost from holding risk.
What does pre-funding cost in a worked example?
About 34 basis points of payout volume in this illustrative scenario. Every number below is an assumption chosen for round math, not data from a real company.
A contractor payments platform sends 3,000,000 USD a month: 1,500,000 to Brazil, 1,000,000 to Mexico, and 500,000 to the eurozone. That is 36,000,000 USD a year. It keeps 12 days of coverage in each currency.
| Input (illustrative) | Value |
|---|---|
| Daily payout volume | 100,000 USD (3,000,000 / 30) |
| Coverage days | 12 |
| Pre-funded balance, all currencies | 1,200,000 USD |
| Cost of capital | 5% a year |
| FX allowance on foreign balances | 2% a year |
| Refills | 3 currencies x 52 weeks = 156 wires at 30 USD |
| Accounts | 3, at 3,000 USD a year each |
| Operations time | 8 hours a week at 60 USD an hour |
| Cost line | Calculation | Annual cost (USD) |
|---|---|---|
| Cost of capital | 1,200,000 x 5% | 60,000 |
| FX allowance | 1,200,000 x 2% | 24,000 |
| Refill fees | 156 x 30 | 4,680 |
| Account maintenance | 3 x 3,000 | 9,000 |
| Operations time | 8 x 52 x 60 | 24,960 |
| Total | 122,640 | |
| Cost in basis points | 122,640 / 36,000,000 x 10,000 | About 34 bps |
Read that last line next to a provider quote. A payout route that looks 20 basis points more expensive per transaction can still be cheaper overall if it lets you drop 34 basis points of pre-funding cost.
Which input moves the result the most?
Coverage days. Capital cost and the FX allowance both scale with the balance, and the balance scales with coverage days.
Same illustrative company, same rates, three coverage settings. The fixed lines (refills, accounts, operations) stay at 38,640 USD.
| Coverage days | Pre-funded balance (USD) | Capital + FX allowance (USD) | Total annual cost (USD) | Cost in bps |
|---|---|---|---|---|
| 5 | 500,000 | 35,000 | 73,640 | About 20 |
| 12 | 1,200,000 | 84,000 | 122,640 | About 34 |
| 20 | 2,000,000 | 140,000 | 178,640 | About 50 |
Two lessons. First, a faster refill path is the cheapest lever you have: every day of lead time removed takes a day of volume out of every currency's balance. Second, expansion multiplies the fixed lines. A fourth country adds an account, a refill schedule, and a buffer, before it adds a single payout.
What are the trade-offs between pre-funding and funding at send time?
Pre-funding buys payout readiness at the cost of idle money. Funding at send time frees the money but makes you plan when funds arrive.
| Pre-funded local accounts | Pre-funded provider balance | Funded at send time | |
|---|---|---|---|
| Idle destination-currency money | High, per country | Medium, in one place | None |
| FX revaluation on idle money | Yes | Yes, if held in local currency | Only between quote and settlement |
| Refill operations | One schedule per country | One schedule | None for destination currencies |
| Exposure to the holder of the balance | Each local bank | The provider | Limited to payouts in flight |
| Payout when funding is late | Still works from the balance | Still works from the balance | Waits for funding |
| Cost of adding a country | New account, buffer, refills | New currency balance | A new recipient bank account type |
The row that favors pre-funding is the fifth one. If recipients expect instant cash-out at 2 a.m. and your dollars arrive by ACH, a balance somewhere is still useful. Size it with the formula instead of by habit. How much USDC to hold to fund payouts applies the same idea to a stablecoin float.
How does funding with stablecoins change the formula?
It sets the destination-currency balance to zero. The stablecoin moves at payout time and converts to local currency at a quoted rate, so there is nothing to park in reais, pesos, or euros.
What stays is a dollar-side float, sized to how long your own funding takes to arrive. That float sits in dollars or stablecoins you control, so lines 2 and 4 mostly disappear and line 3 shrinks to your domestic funding transfers. Correspondent banking vs stablecoin liquidity shows the same shift across five countries, and what "no pre-funding" means defines the three funding models.
None of this makes the recipient deal with crypto. As blockchain payments vs crypto payments explains, the blockchain is the settlement path and the recipient gets local currency in a bank account.
How does BlindPay handle funding?
BlindPay does not require pre-funding. Each payout is funded when you create it, from a stablecoin wallet you control, a BlindPay-managed wallet, or a US virtual account that converts bank deposits into USDC or USDT, and there is no minimum balance to keep in any destination currency.
When you pay from your own wallet, BlindPay operates as a non-custodial payment processor: you authorize the exact quoted amount and BlindPay executes that single transaction. Managed wallets (beta) are custodial when you choose that path. Each payout quote locks the rate and fees for 5 minutes. Fees vary by rail and network and are disclosed in the live quote before you execute; there is no public static rate card.
Payouts land over Pix, SPEI, Transfers, ACH Colombia, SEPA, ACH, wire, RTP, and SWIFT (POBO/COBO). Timing by rail is in the Latin America payout cheat sheet and the SEPA countries list. For the funding side, virtual accounts give each customer a US routing and account number whose deposits settle to stablecoins.
What to do next
Fill in the worked example with your own numbers: monthly volume per currency, coverage days, cost of capital, and the hours your team spends on top-ups. Then compare your pre-funding cost in basis points with the fees in a live payout quote for the same corridor.
Read the BlindPay payout quotes docs and request a quote for your largest corridor to see the per-transaction cost you would compare against.
Once the float is sized, the daily job is matching it. Neobank treasury and reconciliation covers the ledger, bank, and wallet check.
