What is an Annuity?
In finance, an annuity is a series of equal payments made at regular intervals. Examples of annuities include regular deposits to a savings account, monthly insurance payments, or pension payouts. The key elements are a fixed payment amount, a consistent schedule, and a specific interest rate.
How to Use This Annuity Calculator
Our tool helps you determine both the Present Value and Future Value of an annuity:
- Payment Amount (PMT): Enter the amount of each regular payment.
- Interest Rate (r): Enter the annual interest rate (as a percentage).
- Number of Periods (n): Enter the total number of payments.
- Calculate: Find out the total accumulated value (Future Value) or what those future payments are worth in today's dollars (Present Value).
The Mathematical Formulas
If you prefer to calculate annuities manually, here are the standard formulas used by our engine for an Ordinary Annuity:
- Future Value (FV): PMT × (((1 + r)^n - 1) / r)
- Present Value (PV): PMT × ((1 - (1 + r)^-n) / r)
