Swap (rollover) is the interest paid or earned for holding a position overnight. It's based on the interest rate differential between the two currencies.

📐 Swap Calculation Formula
Daily Swap = (Swap Rate × Lot Size × Point Value) / 10 Total Swap = Daily Swap × (Regular Days + Triple Swap Days × 3) Daily Swap = (-6.5 × 1 × $1) = -$6.50/day
With 1 Wednesday: Total = -$6.50 × (6 + 1×3) = -$58.50
Frequently Asked Questions
What is swap in forex trading?
Swap (also called rollover or overnight interest) is the interest paid or earned for holding a forex position overnight. It's based on the interest rate differential between the two currencies in a pair. Use our swap calculator to estimate your swap costs or earnings before trading.
How do I calculate swap in forex?
Swap is calculated using the formula: Daily Swap = (Swap Rate × Lot Size × Point Value) / 10. Our swap calculator automatically computes this for any currency pair, lot size, and holding period, including the triple swap on Wednesdays.
When is swap charged in forex trading?
Swap is charged at the daily rollover time, typically 5:00 PM New York time (server time varies by broker). If you open and close a position within the same trading day, no swap is charged. Use our swap calculator to plan positions around rollover times.
Why is Wednesday swap triple (3x)?
Wednesday swap is tripled to account for the weekend when forex markets are closed but interest still accrues. The extra two days (Saturday and Sunday) are charged on Wednesday's rollover. Our swap calculator automatically includes this triple swap day.
Why do swap rates differ between brokers?
Brokers set their own swap rates based on interbank rates plus their markup. Rates vary based on the broker's liquidity providers, business model, and account type. Always verify your broker's current swap rates in MT4/MT5 or their website.
Can I earn money from forex swap?
Yes! This strategy is called "carry trading." You buy currencies with higher interest rates against those with lower rates. For example, buying AUD/JPY historically earned positive swap because Australia had higher rates than Japan. Use our swap calculator to find profitable carry trade opportunities.
How do I find my broker's swap rates?
In MetaTrader: Right-click on a symbol → Specification → look for "Swap Long" and "Swap Short." Rates are usually in points or pips. You can also find them on your broker's website or by contacting support. Enter these values in our swap calculator.
What are swap-free Islamic forex accounts?
Swap-free (Islamic) accounts comply with Sharia law by not charging or paying interest-based swap. These accounts may have alternative fees or conditions. Many brokers offer swap-free accounts - contact your broker if you require one.
How does swap affect my trading strategy?
For swing and position traders holding trades for days or weeks, swap costs can significantly impact profitability. Negative swap reduces profits, while positive swap adds to gains. Use our swap calculator to factor overnight costs into your trading plan.
What's the difference between swap long and swap short?
Swap Long is the interest rate applied to buy positions, while Swap Short applies to sell positions. One is typically positive (you earn) and one negative (you pay), depending on the interest rate differential between the two currencies. Our swap calculator shows both.
