About This Annuity Calculator
This comprehensive annuity calculator helps you understand the time value of money and make informed decisions about your financial future. Whether you're planning for retirement, evaluating insurance products, or analyzing investment opportunities, this tool provides accurate calculations for all types of annuities.
The calculator supports both ordinary annuities (payments made at the end of each period) and annuities due (payments made at the beginning of each period), with various compounding frequencies to match real-world scenarios.
Formulas Used
Present Value of Ordinary Annuity:
PV = PMT × [(1 - (1 + r)^-n) / r]
Present Value of Annuity Due:
PV = PMT × [(1 - (1 + r)^-n) / r] × (1 + r)
Future Value of Ordinary Annuity:
FV = PMT × [((1 + r)^n - 1) / r]
Future Value of Annuity Due:
FV = PMT × [((1 + r)^n - 1) / r] × (1 + r)
Where: PV = Present Value, FV = Future Value, PMT = Payment Amount, r = Interest Rate per Period, n = Number of Periods

Example Calculations
Example 1: Retirement Annuity
You want to receive $5,000 monthly for 20 years starting at retirement. With a 6% annual interest rate, how much do you need today?
Answer: Present Value = $573,496.06
Example 2: Savings Goal
If you save $500 monthly for 30 years at 7% annual return, how much will you have?
Answer: Future Value = $612,614.67
Example 3: Loan Payment
For a $300,000 mortgage at 4.5% for 30 years, what's the monthly payment?
Answer: Monthly Payment = $1,520.06
Frequently Asked Questions
What's the difference between ordinary annuity and annuity due?
An ordinary annuity has payments made at the end of each period, while an annuity due has payments made at the beginning of each period. Annuity due values are typically higher due to the additional compounding time.
How does compounding frequency affect annuity calculations?
Higher compounding frequency (daily vs. annually) results in higher present and future values because interest is calculated and added more frequently, allowing for more compound growth.
Can I use this calculator for loan payments?
Yes! Loan payments are essentially annuities. Enter the loan amount as present value, interest rate, and term to calculate monthly payments.
What if I have irregular payments?
This calculator is designed for regular, equal payments. For irregular cash flows, you would need a more complex financial calculator or spreadsheet analysis.
How accurate are the calculations?
Our calculator uses precise mathematical formulas and provides results accurate to two decimal places, suitable for most financial planning purposes.
