What is the NPER Function?
The NPER function calculates the number of payment periods for an investment based on constant-amount periodic payments and a constant interest rate.
What is the Nper equation?
That is the number of periodic payments that are needed given the interest rate, opening and closing balances and the payment values required. Formula: NPER= IF Rate =0 THEN (-Pv – Fv)/PMT ELSE LOG((-Rate*Fv+PMT*(1+Rate*Type))/(Rate*Pv+PMT*(1+Rate*Type)))/LOG(1+Rate)
