Swap calculator

What a position costs — or earns — for each night it is held past rollover, from the swap rates the trade server publishes for every symbol. Pick the instrument and direction, enter lots and nights, and tick the box if the hold crosses the triple-swap night, which charges three nights at once.

Financing over 7 nights

−8.40 USD

-12 pts × 0.00001 × 100,000 × 0.1 = −1.20 USD per night

Published swap for EURUSD: long -12, short 0 (points). Negative is a charge, positive a credit.

Rates from the platform configuration of 31 Aug 2026, the same source as the contract specifications. Swaps change; the statement is what applies. Nothing here is a recommendation.

Two kinds of swap, two sums

Forex, metals, indices and energy swaps are quoted in points per lot per night: swap × point size × contract size × lots. EURUSD at −12 points on 0.10 lot is −12 × 0.00001 × 100,000 × 0.10 = −1.20 USD a night. Stock and crypto swaps are an annual percentage of the position value: rate ÷ 365 × price × contract size × lots — which is why the tool asks for a price on those.

Once a week the rollover carries the weekend and charges three nights. For most forex pairs that is Wednesday; for some, Thursday; the tool reads the day from the specification rather than assuming. Held from Monday to the following Monday, a position pays seven calendar nights across five rollovers.

Why the number matters more than it looks

A dollar a night is nothing on one trade and a quarter of the account over a year of always being long the same pair. Run the sum for the way you actually trade — average size, average hold — and compare it with what the strategy makes. The swap guide explains where the rate comes from; the cost guide adds it to spread and commission.
