How Fintechs Actually Make Money on International Transfers

The most visible revenue stream is the take rate — what the provider charges per transfer, either as a fee or rate margin or both.

• Wise: 0% rate margin + ~0.4-0.5% transparent fee on most corridors.
• Revolut: Free up to monthly limit + 0.5-1% above + 1% weekend FX surcharge.
• Remitly: Variable margin (0-1.5% depending on corridor and amount) + tiered fees.
• Sendwave: $0 fee on most African corridors, but 1-2% rate margin.
• Western Union: $5-15 fee + 2-4% rate margin (much higher overall take rate, justified by physical agent network).

Average take rate across the fintech industry: ~1% of volume. Wise reports ~0.6% take rate publicly. At $200B+ in annual volume, that's >$1B in revenue.

When you fund a transfer via ACH and the funds take 1-3 days to clear, the provider earns interest on those funds during that period. Same when funds sit in a recipient's wallet before being withdrawn or spent.

Pre-2022 (when interest rates were near zero) this was negligible. Post-2022 with US rates at 4-5%, float is meaningfully accretive. Wise reported $245M in interest income in FY24, ~25% of total revenue. Revolut similarly benefits.

• Revolut Premium ($10/mo) and Metal ($17/mo): Unlock higher free FX limits, travel insurance, premium card.
• N26 You / Metal (€10-17/mo): Similar travel-focused premium tiers.
• Monzo Premium / Plus (£5-15/mo): Better card, travel insurance.
• Wise: Doesn't have a premium consumer tier; instead monetises Wise Account holders via interest on balances and small per-transaction fees.

Subscription revenue is high-margin and predictable. Revolut publicly attributes ~30-40% of revenue to premium and Metal tiers (combined with interchange — see below).

Every time you tap your Revolut, Wise or Monzo card, the merchant's bank pays interchange (typically 0.2-2% of the transaction). The card issuer gets most of this — meaning the fintech.

Interchange revenue scales with how often you use the card. For Revolut and Monzo, where the card is used heavily for daily spending, interchange is a major revenue stream — possibly the largest after subscriptions.

• Wise Business: Multi-currency accounts, payroll, invoicing for SMEs. Higher take rate (~0.7%) than consumer.
• Wise Platform: White-label international payments for banks (Standard Chartered, Monzo, N26 use Wise infrastructure).
• Revolut Business: Comparable to Wise Business; competitive in Europe.
• Remitly Business / Tap Tap Send Business: Smaller but growing.

B2B is generally higher-margin than consumer because business customers have larger transaction sizes and lower price-sensitivity. Wise Business is reportedly Wise's fastest-growing segment.

• Revolut: Stock trading, crypto trading, savings accounts. Significant interchange-like fees + spread.
• Wise: Recently launched 'Assets' for holding stocks and ETFs in your Wise account.
• Monzo: Mortgage referrals, investing via partners.
• N26: Investment products via partners.

These adjacencies have lower take rates than transfers (often 0.1-0.3%) but extremely high frequency. Revolut's crypto book alone reportedly generated >$300M in revenue at peak.

All major fintechs are moving toward lending: personal loans, working capital for businesses, BNPL. Lending has the highest unit economics of any consumer financial product. Revolut, Monzo and N26 are all pushing here; Wise has historically resisted but is exploring.

Implication: 'free' transfers are a customer-acquisition tool. Once you trust a fintech with daily banking, they can sell you premium subscriptions, interchange-heavy spending, and eventually high-margin loans. The economics are similar to a traditional bank, but with lower customer acquisition cost.

• Free transfers really are free for the provider's marginal cost. They make money elsewhere.
• Holding balances has a cost (to you) — providers earn float on idle funds. Move money out promptly if you don't need it sitting there.
• Premium subscriptions are sometimes worth it for travel-heavy users; usually not for occasional users.
• Card spending gives the provider revenue — if you prefer that, fine. If you prefer to vote with your wallet, withdraw cash.
• Don't worry about the business model — these companies are well-capitalised, regulated, and the AML/KYC framework protects user funds.
