rate of return

[Guest]

How can you calculate the rate of return for a series of payments not
necessarily equal?

Look in Help for IRR or XIR

Yes you can. It's the XIRR function, which is part of the Analysis Tookpal

How can you calculate the rate of return for a
series of payments not necessarily equal?

There is a recurring misconception in the responses
to such questions.

Use IRR whenever the payment __periods__ are equal,
even if the payment amounts (aka cash flows) are
unequal.

Use XIRR whenever the payment __periods__ are
unequal, whether or not the payment amounts are
equal.

Your question is ambiguous with respect to which
case applies.

Note: If the payment periods are "equal", e.g. "once
a month", but interest is compounded daily, you might
want to use XIRR since each month contains a different
number of days (compounding periods).

You're correct that IRR was designed for situations with equal payment periods,
even if amounts are unequal. However, IRR returns a periodic interest rate (like
Rate does). So if your payments are quarterly, you get a quarterly interest
rate. This confuses a lot of people, because they want an annual rate, which is
why XIRR works so well for them.
