Frequently asked questions

How is FD interest calculated in Sri Lanka?

Banks quote an annual rate for the chosen term. For deposits where interest is paid at maturity, interest typically compounds at the payout frequency; for monthly-income FDs, interest is paid out each month and does not compound.

Is tax deducted from fixed deposit interest?

Yes — banks deduct 10% withholding tax (Advance Income Tax) on interest paid to residents. Use our WHT calculator to estimate the deduction and your net interest.

Are fixed deposits safe in Sri Lanka?

Deposits at licensed banks and finance companies are covered by the Sri Lanka Deposit Insurance Scheme up to the prevailing limit per depositor per institution. Check the institution's licence status before depositing.

Where can I find the best FD rates?

AnyBanq's fixed deposit comparison lists current rates from banks and licensed finance companies side by side, refreshed regularly.
