Frequently asked questions
What is the annuity payment formula?
Payment = P × r ÷ (1 − (1 + r)^−n), where r is the monthly rate and n the number of payments.
Is this the same as a loan payment?
Yes. A fixed rate amortizing loan is the same math.
Does it include fees?
No, only interest.
What if the rate is zero?
Divide the amount by the number of payments.
