Time Weighted Return Calculator Guide
The Formula We Use
TWR = [(1 + r1) × (1 + r2) × ... × (1 + rn)]^(1 ÷ n) - 1r1, r2, ... rn = Returns for each sub-periodn = Number of periodsRemoves the effect of cash inflows and outflows
Example Calculation
- TWR = [(1+0.10) × (1-0.05) × (1+0.08)]^(1÷3) - 1
- TWR ≈ [(1.10 × 0.95 × 1.08)]^(1÷3) - 1 ≈ 4.2%
- Time Weighted Return ≈ 4.2%
How to Use This Calculator
- Break your total investment period into sub-periods based on cash inflows and outflows.
- Calculate the return for each sub-period.
- Multiply the growth factors for each period.
- Take the geometric average to find the time weighted return.
Tips for Using TWR
- Best for performance measurement: TWR eliminates the effect of deposits and withdrawals.
- Good for managers: Shows pure investment skill separate from cash flow timing.
- Compare fairly: Makes returns comparable across accounts with different flows.
- More effort: Requires breaking down into multiple periods.
