Who Is This For?
Forex traders who hold positions overnight and need to understand the true cost of carry — especially swing traders and carry trade strategists.
The Formula
Daily Swap = Swap Rate (points) x Pip Value
Pip value depends on the currency pair, lot size, and exchange rate. This calculator handles it automatically.
How to Use This Calculator
- Step 1: Select your currency pair and trade direction (long or short).
- Step 2: Enter your lot size and the number of days you plan to hold.
- Step 3: Enter the swap rates in points from your broker (check MT4/MT5 contract specifications).
- Step 4: Review daily, weekly, and monthly swap costs. Override the exchange rate if needed for accuracy.
Worked Example
Scenario: EUR/USD long, 1 standard lot, swap rate -0.5 points.
Step 1: Pip value = (0.0001 / 1.08) x 100,000 x 1 = $9.26.
Step 2: Daily swap = -0.5 x $9.26 = -$4.63.
Step 3: Weekly = -$4.63 x 7 = -$32.41. Monthly = -$4.63 x 30 = -$138.89.
Assumptions & Edge Cases
- Exchange rates are approximate presets — override for accuracy.
- Swap rates vary by broker and change frequently. Always check your broker for the latest values.
- Does not include commission or spread costs — use the Slippage & Fee Calculator for total cost analysis.
