The SWIFT Minimum Fee: Why a Small International Transfer Costs More, Percentage-Wise, Than a Large One

2026-09-15

Polydirection's fee schedule lists the SWIFT outgoing transfer fee as "0.5%, min 35 EUR." Read quickly, that looks like a straightforward percentage charge — send more, pay proportionally more. It isn't, not below a specific transfer size. Below that size, the "minimum" clause takes over completely, and the fee stops moving with the amount at all. It just sits at 35 EUR, regardless of whether you're sending 3,000 EUR or 300 EUR.

That's not unusual — most banks and payment providers structure international wire fees this way, because processing a SWIFT message costs the same in operational terms whether the underlying amount is small or large. But it does mean the *advertised* rate (0.5%) only describes what you'll actually pay above a certain transfer size. Below it, the real cost — as a share of the amount sent — climbs the smaller the transfer gets.

Where the SWIFT Outgoing Fee Actually Flips: The 7,000 EUR Threshold

The math is simple once you lay it out. The fee is whichever is larger: 0.5% of the amount, or 35 EUR flat. Those two numbers are equal exactly at 7,000 EUR (35 ÷ 0.005). Above that point, the percentage wins and the fee scales normally. Below it, the flat 35 EUR applies no matter how small the transfer gets.

| Transfer amount | Fee charged | Effective rate | |---|---|---| | 500 EUR | 35 EUR | 7.0% | | 1,000 EUR | 35 EUR | 3.5% | | 3,500 EUR | 35 EUR | 1.0% | | 7,000 EUR | 35 EUR | 0.5% (exact threshold) | | 10,000 EUR | 50 EUR | 0.5% | | 30,000 EUR | 150 EUR | 0.5% |

A 500 EUR outgoing SWIFT transfer effectively costs 7% in fees — fourteen times the advertised 0.5% rate. That's not a hidden charge or a mispriced product; it's the arithmetic of a percentage-with-a-floor structure that most fee pages don't spell out in plain numbers.

Incoming SWIFT Transfers Have Their Own, Lower Threshold

The incoming SWIFT fee follows the same logic at smaller numbers: 0.2%, minimum 10 EUR. The flip point here is 5,000 EUR (10 ÷ 0.002). A 500 EUR incoming SWIFT payment costs 10 EUR — a 2% effective rate, ten times the advertised 0.2%. A 10,000 EUR incoming payment costs 20 EUR, right at the advertised 0.2%.

The pattern is identical to outgoing transfers, just with a lower floor and a lower threshold — which makes sense, since the incoming fee itself is set lower across the board. The underlying mechanic, though, is the same: below a specific transfer size, you're paying a fixed cost dressed up as a percentage.

Why SEPA Doesn't Have This Problem — And Why That's Not Always an Option

SEPA outgoing transfers on the same fee page are priced completely differently: a flat 3 EUR, full stop, no percentage and no threshold to calculate. A 500 EUR SEPA transfer and a 50,000 EUR SEPA transfer cost exactly the same 3 EUR. There's no floor to trip over because there's no percentage component to floor in the first place.

That's a genuinely simpler pricing model — but it only applies within the SEPA network, which covers EUR transfers inside the EU/EEA plus a handful of participating countries. The moment a payment needs to move outside that network, or in a currency SEPA doesn't support, SWIFT becomes the only option, and the minimum-fee mechanics come back into play regardless of how small the payment is.

What This Means for How You Batch or Time International Payments

None of this changes the advertised rate — 0.5% and 0.2% are exactly what's published, and neither number is misleading on its own. What it does mean is that the real cost of a specific transfer depends heavily on where it sits relative to the 7,000 EUR and 5,000 EUR thresholds. A business that regularly sends several smaller international payments below those thresholds is paying a materially higher effective rate than one sending fewer, larger ones — same bank, same published fee schedule, same rails.

If timing or batching payments is operationally possible — combining several smaller SWIFT transfers into one that clears the threshold, for example — the math above is the exact reference point for whether that's worth doing. Below 7,000 EUR outgoing or 5,000 EUR incoming, the flat minimum is doing all the work; above it, the percentage is.
