Quick answer

With MT4/MT5 swap rates in points, swap per night = swap points × point size × contract size × lots, converted to your account currency, and the total = swap per night × (nights + 2 × triple-swap nights). A −7.5-point swap on 1 lot of EUR/USD is −$7.50 a night, so 5 nights including one Wednesday triple cost 7 × $7.50 = $52.50.

What is the Forex Swap Calculator?

Swap — also called rollover or overnight financing — is the amount a broker charges or credits for holding a position through its daily rollover, usually 5 p.m. New York time. For currency pairs it reflects the interest-rate difference between the two currencies plus the broker's markup; for CFDs it is a financing rate on the position value. Long and short positions have separate rates, and both can be negative.

Brokers publish swap in three ways, and the calculator handles each:

  • Points (MT4/MT5) — swap per night = swap points × point size × contract size × lots, converted to your account currency. A point is 0.00001 on EUR/USD and 0.001 on USD/JPY.
  • Money per lot — a fixed amount in your account currency per lot per night.
  • Annual % — swap per night = position value × annual rate ÷ 365 (some brokers use a 360-day year), common for index, metal and crypto CFDs.

Total swap = Swap per night × (Nights held + 2 × Triple-swap nights)

Once a week one rollover is charged three times to cover the weekend. For spot forex this is usually Wednesday night, because a position held through it settles after the weekend; many CFDs charge the triple on Friday.

How to use this calculator

  1. Instrument and Account currency — a conversion rate field appears when one is needed, with a reference rate filled in.
  2. Direction — Long (buy) or Short (sell). The calculator uses the swap rate for that side.
  3. Swap quoted as — Points (MT4/MT5), Money per lot, or Annual %. In Annual % mode a price field appears so the position value can be calculated.
  4. Swap long and Swap short — enter them signed as your broker shows them: negative means you pay, positive means you earn. In MT4/MT5 they are under Symbol → Specification.
  5. Position size (lots).
  6. Nights held — the number of rollovers the trade stays open through. Monday to the following Monday is 5.
  7. Triple-swap nights — how many of those nights are charged three times (usually one per week).

The result shows the total swap paid or earned, the swap per night and the number of nights charged. Show the math gives the per-night calculation and any currency conversion; Copy link with these numbers saves it.

Worked example

EUR/USD long, points. Swap long −6.5 points, 1 lot, held 7 nights including one Wednesday. Per night: −6.5 × 0.00001 × 100,000 × 1 = −$6.50. Nights charged: 7 + 2 × 1 = 9. Total: −$58.50.

USD/JPY long, points, USD account. Swap long +10 points, 1 lot, 1 night: 10 × 0.001 × 100,000 = ¥1,000, which is ¥1,000 ÷ 150 = +$6.67 at USD/JPY 150.

Gold, annual %. 1 lot at $2,000 is a $200,000 position. At −5% a year, one night costs $200,000 × 5% ÷ 365 = −$27.40.

When to use it

  • Swing and position trades — swap is charged every night and adds up over weeks.
  • Before the triple-swap night — to decide whether to close or hold through it.
  • Carry trades — to check what a positive swap actually pays after the broker's markup.
  • Comparing brokers — swap rates for the same instrument can differ widely.

Common mistakes

  • Treating points as pips. On a 5-decimal pair, 10 points is 1 pip. A −6.5-point swap on 1 lot of EUR/USD is −$6.50 a night, not −$65.
  • Ignoring the triple night. Holding through Wednesday (or Friday on many CFDs) costs three nights at once.
  • Assuming positive swap is guaranteed. Brokers change swap rates, often when central banks change interest rates, and a positive swap does not offset an adverse price move.
  • Using the other side's rate. Long and short swaps differ and are often both negative.

Frequently asked questions

When is swap charged?

At the broker's daily rollover, usually 5 p.m. New York time (21:00 or 22:00 UTC, depending on US daylight saving time). A position closed before the rollover pays no swap for that day.

Why is swap charged three times on Wednesday?

Spot forex settles two business days after the trade. A position held through Wednesday's rollover settles after the weekend, so it is financed for Saturday and Sunday as well. Many CFDs charge the triple on Friday instead; check your broker's specification.

Where do I find my broker's swap rates?

In MT4/MT5, right-click the symbol in Market Watch and choose Specification: swap long and swap short are listed with their type (points, money or percent). Brokers also publish them on their contract specification pages.

Can I avoid swap?

Close positions before the rollover, or use a swap-free (Islamic) account where offered — these often charge a fixed fee instead after a number of nights.

Why does swap change over time?

It follows interest rates and the broker's own financing costs. When a central bank changes its policy rate, swap rates on that currency's pairs usually change soon after.
