Annuity Calculator

An annuity is a series of equal payments made at regular intervals. Annuities are commonly used in retirement planning, loan calculations, and investment analysis. Our calculator helps you determine the present and future value of any annuity.

The calculator supports both ordinary annuities (payments at end of period) and annuity due (payments at beginning of period), providing comprehensive analysis for various financial scenarios.

Types of Annuities:

• Ordinary Annuity: Payments made at the end of each period
• Annuity Due: Payments made at the beginning of each period
• Immediate Annuity: Payments start immediately
• Deferred Annuity: Payments start at a future date

Annuity Formulas:

Present Value of Ordinary Annuity:

PV = PMT × [(1 - (1 + r)^-n) / r]

Future Value of Ordinary Annuity:

FV = PMT × [((1 + r)^n - 1) / r]

Annuity Due:

Multiply ordinary annuity result by (1 + r)
