What this specific question is asking

Each input for this calculation has to mean the same thing on your side as it does in Annuity Calculator: check that payment per period, annual rate (%) and number of years are entered in the units and periods the tool expects, then read the output with those same units attached.

A fast validation: take the worked example (As a worked reference for “How to find the annuity”, Worked example…), swap in your own payment per period, and confirm the result shifts in the direction the relationship predicts. If it moves the wrong way, recheck the units before the math.

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 “How to find the annuity”, 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

The output is only useful against a reference. The example's 50,000 × ((1 gives that reference: your own result should be explainable against it — larger or smaller for a reason you can name. 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.
