Next: RD calculatorThe same idea, with a deposit every month.

One deposit at the start. Quarterly compounding is the usual bank default. No tax is deducted.

How this is calculated

How it works
  1. Step 1

    Principal

    One deposit at the start. No monthly top-up.

  2. Step 2

    Compounding

    Quarterly is the default. The annual rate is split across the year.

  3. Step 3

    Maturity

    The figure is before tax. A bank may deduct some.

Fixed deposit maturity

A = P × (1 + r ÷ n)^(n × t)

What the symbols mean
PPrincipal.
rAnnual interest rate as a decimal.
nTimes the bank compounds each year. 4 is quarterly.
tYears.

Quarterly is the usual published FD convention: the annual rate is divided by 4, and that rate is applied four times a year.

A monthly installment, rather than one principal, is a recurring deposit. One investment compounded monthly is the lump sum calculator.

Questions

Why is quarterly the starting point?

Many bank FDs compound interest every quarter. Switch the control if the deposit you are reading compounds yearly, monthly, or daily.

Is tax taken out?

No. The maturity is before tax. A bank that deducts tax at source will pay you less than this figure.

Can I add a monthly top-up?

Not on this page. That is either compound interest, a SIP, or a recurring deposit, depending on which convention you want.
