What this specific question is asking

Annuity Calculator applies one fixed relationship to your inputs. Your part of the work is the inputs: payment per period, annual rate (%) and number of years, each checked for unit and period before entry. Everything else is arithmetic.

Test the setup before trusting the output: rerun the example with a doubled payment per period and see whether the result behaves as the formula implies. Direction first, precision second.

Inputs to verify

Verify payment per period before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify annual rate (%) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify number of years before calculation; if this value uses a different unit, period or definition, convert or restate it first.

Step-by-step check

Enter the equal payment made each year.
Type the annual rate of return earned on each payment.
Set the number of years the payments continue (whole years only, since each payment is annual).
Tap Calculate to see the annuity's future value and total contributions.

Worked example and sanity check

As a worked reference for “Fers annuity example”, Worked example The future value of an annuity of 50,000 deposited each year for 10 years at 8% is 50,000 × ((1.08 10 − 1)/0.08) = 724,328.12 — the worth of all the yearly payments at the end of the term, not their present value.

Interpreting the result

So what does the number mean? In the worked example the calculation produced 50,000 × ((1. A result in that range is plausible for this kind of input; if your result lands far from it, revisit payment per period first — it is the input most often entered on the wrong basis. Treat the figure as an estimate under stated assumptions, not a promise of returns or a lending decision; fees, taxes and rate resets will move the real outcome.
