How much does holding this forex position overnight actually cost me in swap or rollover fees?

Calculates the total swap or rollover cost of a forex position from lot size, swap rate per standard lot per night, nights held, and how many of those nights carry a triple-swap charge.

How is this calculated?

Total swap cost equals lot size multiplied by the swap rate multiplied by nights held, plus two extra charges of that same base amount for each night flagged as a triple-swap night.

How this is calculated

Swap (also called rollover) is charged or credited once per night a forex position stays open past the broker's daily rollover time, based on the interest rate differential between the two currencies.
This tool multiplies your lot size by the swap rate you enter and the number of nights held. It does not look up live swap rates, since those change with interest rate policy and differ by broker.
Most brokers charge a triple swap one night a week to account for weekend settlement, since banks don't settle trades on Saturday or Sunday. Confirm which day your broker uses, it isn't universal.
A position with a swap cost that's large relative to its expected profit target is a genuine drag on a multi-day forex trade, and worth checking before you hold something over several nights, not after.
