Understanding Annuity Calculations
An annuity is a financial product that provides a stream of payments over time. This calculator uses standard financial formulas to compute key annuity metrics.
Key Formulas Used
Ordinary Annuity Future Value:
FV = P × [(1 + r)ⁿ – 1] / r
Annuity Due Future Value:
FV_due = FV × (1 + r)
Ordinary Annuity Present Value:
PV = P × [1 – (1 + r)⁻ⁿ] / r
FV = P × [(1 + r)ⁿ – 1] / r
Annuity Due Future Value:
FV_due = FV × (1 + r)
Ordinary Annuity Present Value:
PV = P × [1 – (1 + r)⁻ⁿ] / r
Where:
- P = Periodic Payment Amount
- r = Periodic Interest Rate
- n = Total Number of Periods
- FV = Future Value
- PV = Present Value
