About This Tool
Future Value of Annuity Calculator helps you estimate the future value of recurring deposits using the nirmion future-value engine with the annuity fields surfaced up front without leaving the browser.
Use this calculator to find the future value of annuities due, ordinary regular annuities and growing annuities.
This page opens with a focused preset flow. Keep compounding (m) set to 12 times per period. Keep pmt amount (pmt) set to 0. Keep pmt growth (g) % set to 0.
What This Tool Does
The future value of annuity calculator is built for people who want a fast answer and a clearer understanding of what affects the final output.
It works best when you enter realistic values for Number of Periods (t), Rate (R) % per period, Compounding (m), Pmt Amount (PMT). If the tool includes select boxes or toggles, choose the scenario that matches your use case before you calculate.
The purpose of this calculator is to compute the future value of a series of deposits. This is an investment or saving account and, you are calculating the accumulation of a series of deposits, the annuity payments, and what the total value will be at some time in the future.
Helpful variable notes from the matched source page: Period: commonly a period will be a year but it can be any time interval you want as long as all inputs are consistent.; Number of Periods (t): number of periods or years; Interest Rate (R): is the annual nominal interest rate or "stated rate" per period in percent. r = R/100, the interest rate in decimal
The core formula used by this calculator is FV = PMT \times \frac{(1 + r)^n - 1}{r}. Reviewing it can help you validate the output and understand how the variables interact.
Formula
FV = PMT \times \frac{(1 + r)^n - 1}{r}The formula below gives the core relationship, while the mode and option fields decide which version or return value the calculator should use.
Use the formula as a quick reference to understand how the entered values influence the final output.
Variables and Inputs
Number of Periods (t)
Enter a numeric value; this field is required; min 0; Required. Enter the number of periods (t) value. Accepted range: minimum 0..
Rate (R) % per period
Enter a numeric value; this field is required; Required. Enter the rate (r) % per period value..
Compounding (m)
Choose the option that matches your use case; this field is required; Required. Choose the compounding (m) option that matches your calculation. Default: 12 times per period..
Pmt Amount (PMT)
Enter a numeric value; this field is optional; min 0; Optional. Enter the pmt amount (pmt) value. Accepted range: minimum 0. Default: 0..
Pmt Growth (G) %

Payments At (T)
Choose the option that matches your use case; this field is required; Required. Choose the payments at (t) option that matches your calculation. Default: End of each period (ordinary)..
Calculation Modes and Options
Compounding (m)
Compounding (m) changes how the calculator behaves. Available choices: 1 time per period, 2 times per period, 4 times per period, 12 times per period, 365 times per period, Continuous compounding.
Payments At (T)
Payments At (T) changes how the calculator behaves. Available choices: Start of each period (due), End of each period (ordinary).
How It Works
- Keep compounding (m) set to 12 times per period.
- Keep pmt amount (pmt) set to 0.
- Keep pmt growth (g) % set to 0.
- Enter Number of Periods (t), Rate (R) % per period, Compounding (m), Pmt Amount (PMT) in the calculator fields.
- Review the required options and units before running the calculation.
- Click Calculate to generate the result instantly from the current inputs.
- The current calculator logic follows this formula: FV = PMT \times \frac{(1 + r)^n - 1}{r}.
Common Scenarios
Quick future value of annuity calculator checks
Use this when you need a fast answer for homework, planning, estimation, verification, or daily work involving Number of Periods (t), Rate (R) % per period, Compounding (m), Pmt Amount (PMT).
Compare nearby scenarios
Change one input at a time to see which value has the strongest effect on the result and to sanity-check your assumptions.
Use the formula as a cross-check
Review the formula alongside the calculator result when you want an extra confidence check or need to explain the math behind the answer.
Examples
Worked examples help visitors sanity-check the calculator before relying on the result in a real workflow.
Basic future value of annuity calculator example
Run a straightforward example first so you can see how the future value of annuity calculator responds before trying edge cases.
- Enter a sample value for Number of Periods (t).
- Enter a sample value for Rate (R) % per period.
- Keep Compounding (m) set to 12 times per period.
Expected outcome: Review the calculated output and note which input changes the result the most.
Compare two scenarios
Run the calculator once with baseline values, then change one important input and calculate again.
- Use your first set of values as a baseline.
- Change one key input only and rerun the calculation.
- Compare the difference in the result to understand sensitivity.
Expected outcome: This comparison helps explain which field has the strongest impact on the final answer.
Use the formula as a check
Match the page formula with your inputs to verify the output manually.
- Copy the formula shown for future value of annuity calculator.
- Plug in the same values you entered in the tool.
- Compare your manual estimate with the on-page result.
Expected outcome: If both match closely, you know the calculation path is behaving as expected.
Common Input Mistakes
- Check units before you calculate. Mixed units are one of the most common reasons a correct formula produces the wrong answer.
- Fill the required fields first. Optional fields should refine the result, not replace the core inputs.
- Confirm the selected mode before rerunning the calculator. A different option can change the interpretation of the same numeric inputs.
- Stay within the intended input range. Extremely large, negative, or out-of-range values can make the output unrealistic even when the page accepts them.
