Example Data Table

Periodic Payment	Annual Rate	Years	Payments/Year	Compounds/Year	Annuity Type	Illustrative Outcome
$500.00	6.00%	10	12	12	Ordinary	Steady monthly deposits build long-run savings.
$800.00	5.50%	15	4	12	Due	Earlier payments generally increase ending value.
$1,200.00	7.25%	20	12	12	Ordinary	Higher duration and rate amplify compound growth.

Formula Used

Periodic rate:

i = (1 + r / c)^{c / p} − 1

Ordinary annuity future value:

FV = PMT × [((1 + i)ⁿ − 1) / i]

Annuity due future value:

FV_due = FV_ordinary × (1 + i)

Zero-rate case:

FV = PMT × n

Here, PMT is the payment amount, r is the annual nominal rate, c is compounding periods per year, p is payment periods per year, i is the effective rate per payment period, and n is total payments.

Frequently Asked Questions

1. What does future value of an annuity mean?

It is the total accumulated value of repeated equal payments after earning interest over time. The calculator combines contributions and compound growth into one ending balance.

2. What is the difference between ordinary annuity and annuity due?

An ordinary annuity assumes payments happen at each period’s end. An annuity due assumes payments happen at each period’s beginning, so each deposit earns interest for one extra period.

3. Why are payment frequency and compounding frequency separate?

Some investments compound monthly while contributions are quarterly or weekly. Separating both frequencies gives a more realistic effective rate for each payment period.

4. What happens when the interest rate is zero?

The future value becomes the simple total of all contributions. No compound growth occurs, so the ending balance equals payment amount multiplied by the number of payments.

5. Can I use this calculator for retirement planning?

Yes. It works well for retirement deposits, education funds, sinking funds, and other regular savings plans. It is useful for projections, not guaranteed investment outcomes.

6. Why does annuity due usually give a higher value?

Because every payment is made earlier, each deposit has more time to earn interest. That extra compounding period increases the final accumulated value.

7. What does the chart display?

The chart plots estimated balance growth after each payment period. It helps visualize how repeated deposits and compounding work together across the full investment horizon.

8. What do the CSV and PDF downloads include?

They include the main inputs, summary results, and yearly schedule values shown on the page. This makes saving, sharing, and reviewing calculations easier.
