Term Deposit Calculator — Fixed Deposit Interest
See exactly what a term deposit (fixed deposit) will pay: enter the amount, the annual rate, the term in months and how the bank compounds interest, and get the maturity balance, gross and after-tax interest, and the effective annual yield.

How does this calculator work?
A term deposit grows to P × (1 + r/n)^(n·t) with compounding (or P × (1 + r·t) with simple interest at maturity). Enter amount, rate, term and compounding to get the maturity balance, interest after any withholding tax, and the effective annual yield for comparing offers.
Formula
How this is calculated
A term deposit locks your money at a fixed annual rate for a fixed term. Banks credit the interest in different ways: compounded monthly, quarterly or yearly (interest is added to the balance and itself earns interest), or as simple interest paid once at maturity. Pick the option from your deposit contract — for the same nominal rate, more frequent compounding gives a slightly higher maturity value.
The calculator converts the term to years and applies the standard compound-interest formula P × (1 + r/n)^(n·t), where n is the number of compounding periods per year, or the simple-interest formula P × (1 + r·t) for interest paid at maturity. If your country withholds tax on deposit interest, enter the rate — many European countries do (for example around 25.5% in Latvia, 15% in Greece or 8% in Bulgaria) — and the tax is subtracted from the gross interest to give your net payout.
The effective annual yield converts the after-tax result back into a single comparable percentage per year, so you can compare deposits with different terms and compounding schedules side by side. The month-by-month curve shows how the balance grows over the term.
Frequently asked questions
With simple interest the bank pays interest only on your original deposit, once at maturity. With compound interest, credited interest is added to the balance and earns interest itself — so the same nominal rate yields more, and the gap grows with longer terms and more frequent compounding.
In many countries banks withhold tax on interest automatically — rates vary widely (commonly 8–30% in Europe). Enter your country’s withholding rate in the tax field to see the net payout; leave it at 0 if your interest is tax-free or below an exemption threshold.
Most banks reduce or cancel the accrued interest on early withdrawal, and some charge a fee. This calculator assumes you hold the deposit to maturity — for early-withdrawal scenarios, check your bank’s specific penalty terms.
