Excel RATE function

Calculates the interest rate per period of a loan or an installment purchase. In Spanish Excel it is called TASA.

Syntax

English Excel

=RATE(nper, pmt, pv, [fv])

Spanish Excel (Mexico)

=TASA(núm_per, pago, va, [vf])

Spanish Excel (Spain, Latin America)

=TASA(núm_per; pago; va; [vf])

ArgumentWhat it is
nperThe number of payments.
pmtThe payment each period (negative).
pvThe amount received today.
fvoptionalBalance at the end.

Example

"12 payments of 1,150" sounds fine, but what interest are you paying? RATE(periods, payment, amount) returns the rate per period. Multiply it by 12 for the annual rate.

=RATE(B2,-B3,B1)

Common mistake

It returns the rate per period: with monthly payments, multiply by 12 for the annual rate. Payment and amount must have opposite signs.
