How the SIP backtest works
On your SIP day each month we buy units at that day’s NAV (or the next business day). The step-up increases the instalment once a year. All units are then valued at the latest NAV, and the return is measured with XIRR — the same method fund houses use in SIP performance statements. Compare the result with a lump sum invested on the first SIP date to see how rupee-cost averaging worked for this fund.
