Calculator Inputs

Periodic Payment

Example Data Table

Scenario	Periodic Payment	Annual Rate	Years	Compounding	Payment Frequency	Timing
Starter Plan	250.00	6.00%	5	12	12	Ordinary
Growth Plan	500.00	8.00%	10	12	12	Due
Long Horizon	1000.00	9.50%	20	4	12	Ordinary

Formula Used

For a standard ordinary annuity with matching payment and compounding periods, the future value formula is:

FV = PMT × [((1 + r)^n - 1) / r]

For an annuity due, where payments occur at the beginning of each period, the value is multiplied by one extra growth factor:

FV_due = PMT × [((1 + r)^n - 1) / r] × (1 + r)

Where:

FV = future value of the annuity
PMT = regular payment amount
r = periodic effective interest rate
n = total number of payment periods

This calculator first converts the annual nominal rate and compounding frequency into an effective rate per payment period. It then simulates each payment period one by one, which supports annuity due timing, an optional starting principal, and optional payment growth.

Frequently Asked Questions

1) What is a future annuity value?

It is the accumulated value of a series of recurring payments after earning compound interest over time. It helps estimate how regular savings can grow by a future date.

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

Ordinary annuity assumes payments occur at the end of each period. Annuity due assumes payments occur at the beginning, so every deposit earns interest for one extra period.

3) Why do compounding and payment frequencies both matter?

Interest may compound on a different schedule than deposits are made. This calculator converts the annual rate into an effective rate per payment period for more realistic growth estimates.

4) Can I include an existing balance?

Yes. Enter your starting principal in the initial principal field. The calculator grows that amount alongside your recurring deposits for the selected time horizon.

5) What does annual payment growth mean?

It lets each deposit increase gradually over time. This is useful when you expect contributions to rise with income, inflation adjustments, or a planned savings escalation strategy.

6) Is this calculator useful for monthly savings plans?

Yes. Monthly savings is one of the most common annuity cases. Select monthly payments and your preferred compounding frequency to estimate long-term growth.

7) Does the result guarantee actual investment performance?

No. The output is a mathematical projection based on constant assumptions. Real returns can vary because of fees, taxes, changing rates, and market fluctuations.

8) What should I review after calculating?

Compare future value, contributions, and interest earned. Then inspect the schedule and chart to understand how timing, frequency, rate, and payment growth affect the outcome.
