Często Zadawane Pytania

What is an ordinary annuity?
A series of equal payments made at the end of each period, which is the convention this calculator assumes.
Which figure should I use for planning — future value or present value?
Future value tells you what a stream of payments will grow to; present value tells you what that same stream is worth today.
What inputs does the Annuity Calculator need?
You'll need to provide: Payment / period, Rate / period (%), Number of periods. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Annuity Calculator?
The Annuity Calculator applies the formula exactly as calculated — Ordinary annuity — Future value = payment × [((1+r)ⁿ − 1)/r]. Present value = payment × [1 − (1+r)⁻ⁿ]/r, where r is the periodic rate and n is the number of periods. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Are these results guaranteed?
No. The Annuity Calculator gives an estimate based on the numbers you enter and standard financial formulas — actual rates, fees, taxes, and terms vary by lender, institution, and jurisdiction, and can change over time. This is not financial advice; consult a qualified financial professional for decisions specific to your situation.
Is the Annuity Calculator free to use?
Yes, the Annuity Calculator is completely free, requires no signup, and runs instantly in your browser.
