Forex Swap and Financing Calculator
Estimate long and short financing from daily cash costs, lots and calendar rollover dates. Choose the triple-charge day from your broker’s specification.
Understand the rollover convention
This scenario counts each Monday–Friday rollover once and the chosen triple-charge weekday three times. Saturdays and Sundays add no separate rollover. A seven-calendar-day interval therefore normally contains seven charged day units. The first date is the first rollover actually crossed, not simply the trade’s calendar opening date.
Cost = daily cash cost per lot × volume × charged day units. The daily input is held constant. The calculator does not automatically convert swap points or annual interest percentages. Convert them using the broker’s symbol specification before entering the cash amount.
When the estimate differs from MT5
Holidays, instrument settlement, broker server cut-off, dividend adjustments, administrative charges and swap-free account rules can change the schedule. Some instruments have different weekend charging. Use a broker-specific statement for those cases. A credit today can turn into a charge later.
Transfer the resulting total into the cost comparison or net P/L calculator.
Frequently asked questions
Why can Wednesday count three times?
Many forex specifications charge a triple rollover to account for settlement over a weekend. The correct day depends on the instrument and broker; choose it from the actual specification.
Can I paste a swap rate in platform points?
Not directly. The inputs are cash cost per lot per charged day in account currency. Convert a points-based quote first, and check holidays or special financing conventions separately.
