Malaysia fixed deposit calculator

FD interest, maturity value, and auto-renewal compounding.

Work out the interest and maturity value of a Malaysian fixed deposit (FD). Banks pay simple interest pro-rated to the tenure, paid at maturity — nothing compounds inside a tenure. Compounding happens only when you renew and roll the interest into the new placement, once per tenure. The calculator also models breaking the deposit early and checks the maturity value against the PIDM protection limit. FD interest from licensed banks is tax-exempt for individuals.

How the fixed deposit calculator works

Simple interest is your principal multiplied by the annual rate and the fraction of a year you hold the deposit: principal × rate × (months ÷ 12).

The maturity value is principal plus that interest, paid out when the FD matures.

Nothing compounds during a tenure. If you renew the deposit, the interest earned is rolled into the new principal and earns interest in the next cycle — so compounding happens once per completed tenure, not monthly. A single placement earns no compounding bonus at all.

Because of that, a shorter tenure rolled over repeatedly compounds more often than a long one, which is why the calculator reports an effective annual return alongside the headline rate.

Breaking the deposit early is costly. Common bank practice pays nothing at all before three completed months, and about half the contracted rate after that, on completed months only. Terms vary between banks.

PIDM protects RM250,000 per depositor per member bank, and the limit counts principal and interest together — so a placement that starts under the cap can mature above it. Conventional and Islamic deposits are protected separately.

Fixed deposit formulas

Simple maturity = P × (1 + r × months ÷ 12).

Value after n renewals = P × (1 + r × months ÷ 12)^n, where P = principal, r = annual rate (÷100) and months is the tenure of one placement.

Early withdrawal interest = P × (r ÷ 2) × completed months ÷ 12, and zero before three completed months.

Worked examples

RM10,000 at 3.5% p.a. for 12 months

  • Principal: RM10,000
  • Rate: 3.5% p.a.
  • Tenure: 12 months

Result: Simple interest of RM350 → RM10,350 at maturity, and no compounding bonus, because a single placement does not compound. Renew it for a second 12-month term and the interest rolls in: RM10,712.25, or RM12.25 more than simple interest over the same two years. Break it at month 6 instead and you would receive RM10,087.50 — half the rate on completed months only, giving up RM262.50.

Frequently asked questions

Is fixed deposit interest taxable in Malaysia?
Interest earned on deposits with licensed banks and finance companies is tax-exempt for resident individuals, so you keep the full amount shown.
Should I pick a long or short tenure?
Longer tenures often carry slightly higher rates but lock up your money for longer. Many savers ladder several FDs across different tenures so some matures regularly while still earning competitive rates.
What happens if I withdraw before maturity?
Early withdrawal usually means you forfeit some or all of the interest for that placement, depending on the bank's terms. The principal is protected and insured by PIDM up to RM250,000 per depositor per bank.
