XNPV
XNPV is the date-aware version of NPV: it discounts each cash flow to a present value using the exact number of days between the first date and each cash flow date, rather than assuming equal periods. Use it for real-world investment analysis where cash flows do not arrive at perfectly regular intervals.

How it works
- 1List cash flow dates in column A (as proper date values) and corresponding amounts in column B.
- 2The first date is treated as the valuation date; the first cash flow can be the initial investment (negative).
- 3Type =XNPV(rate, values, dates) — e.g. =XNPV(0.1,B2:B5,A2:A5).
