What is annuity math?
An annuity is a series of payments made at equal intervals. Examples of annuities are regular deposits to a savings account, monthly home mortgage payments, monthly insurance payments and pension payments. Annuities may be calculated by mathematical functions known as “annuity functions”.
How is time calculated in an annuity?
Solving for the number of periods can be achieved by dividing FV/P, the future value divided by the payment. This result can be found in the “middle section” of the table matched with the rate to find the number of periods, n.
What is the formula for calculating annuity interest?
Ultimately, to calculate the interest rate in an ordinary annuity, the equation is expressed A = P(1 + rt).

How to calculate the total amount of an annuity?
A = P r ∗[1−(1+r)−t] A = P r ∗ [ 1 − (1 + r) − t] A is the total amount of the annuity, P is the payment, r is the interest rate, and t is the number of periods. Make sure to be consistent with the time period – if you use months, you have to divide the annual interest rate by 12 and multiply the number of years by 12.
Do you use exponents for annuities in math?
We can use exponents to help. 1 1+r is actually (1+r) −1 and 1 (1+r)× (1+r) is (1+r) −2 etc: To simplify that further is a little harder!
