About Annuities
An annuity is a series of equal payments made at regular intervals. Annuities are commonly used in retirement planning, loan payments, and investment analysis.
Types of Annuities
- Ordinary Annuity: Payments made at end of each period
- Annuity Due: Payments made at beginning of each period
- Immediate Annuity: Payments start immediately
- Deferred Annuity: Payments start at a future date
Annuity Formulas
Future Value: FV = PMT × [((1 + r)^n - 1) / r]
Present Value: PV = PMT × [(1 - (1 + r)^-n) / r]
Payment: PMT = PV × [r / (1 - (1 + r)^-n)]
Present Value: PV = PMT × [(1 - (1 + r)^-n) / r]
Payment: PMT = PV × [r / (1 - (1 + r)^-n)]
