🔁 Annuity Calculator
How It Works
Calculate the future value of regular periodic deposits at a fixed interest rate. Use Annuity Calculator to explore how the main financial inputs change the payment, cost, return, or cash-flow result before making a decision.
The result is most useful when the inputs match the definitions used by this calculator. For this tool, the underlying method is: FV = PMT × [((1+r)^n − 1) / r]. Compare the output with the worked example, then change one meaningful input at a time to see how the result responds.
Understanding Annuity
Annuity is a financial calculation that uses the inputs shown above to estimate a payment, amount, rate, return, cost, or planning value.
Keep in mind: Financial calculations depend on assumptions and may not include every fee, tax, market change, or contractual term. Review the annuity inputs and units before relying on the result.
When to Use This Calculator
Use Annuity Calculator to explore how the main financial inputs change the payment, cost, return, or cash-flow result before making a decision.
Practical tip: For this Annuity Calculator, change one financial assumption at a time—such as the rate, amount, contribution, fee, or tenure shown in the inputs—so you can see which factor drives the result.
Formula
FV = PMT × [((1+r)^n − 1) / r]
Example
Depositing $500 each period at 5% for 10 periods grows according to the annuity formula.
