FD Rates in Sri Lanka — Fixed Deposit Interest Rate Comparison
Every rupee fixed deposit rate 7 Sri Lankan banks publish themselves, ranked by tenure and payout — with the interest you keep after 10%Advance Income Tax and the true effective rate, so a monthly-interest deposit compares honestly against an at-maturity one. Each row carries the bank's own effective date.
How it works
This page does two separate jobs, and keeping them apart is what makes it trustworthy. The first is a registry: a dated snapshot of the rupee fixed deposit rates that 7 Sri Lankan licensed banks publish on their own sites, read by hand on 2026-09-22. No figure here comes from an aggregator, a news article or an older version of a bank's sheet, and where a bank publishes nothing for a tenure or a payout mode the table says so rather than filling the gap. The second job is arithmetic, which depends on no external data and is exact.
Write r for the published nominal annual rate, P for the deposit and t for the tenure in years.
- At-maturity deposits accrue simple interest:
gross = P × r × t. A six-month deposit at 9.75% pays half of 9.75%, and a five-year deposit at 12.50% pays 62.50% in total — not the 80.2% annual compounding would give. - Monthly-payout deposits pay
P × r ÷ 12each month and return the principal untouched at the end. Nothing compounds inside the deposit. - Advance Income Tax of 10% of gross interest is withheld at source under IRD Notice PN/IT/2025-01, so
net = gross × 0.9. With a self-declaration on file the deduction is nil. - The annual effective rate (AER) is what makes tenures and payout modes comparable. At maturity it is
(1 + r·t)^(1/t) − 1; for monthly payout it is(1 + r/12)^12 − 1, assuming every monthly payment is reinvested at the same nominal rate.
That AER formula is not asserted here — it is tested. Six of the seven publishing banks print their own Annual Effective Rate beside their rates, and those printed figures are never used in a calculation on this page. Instead each one is recomputed from the bank's nominal rate and compared. All 91 of the 91 published AER figures in this registry reproduce, the worst gap across seven banks being 2.2 basis points. That is also how the simple-interest reading of multi-year deposits is confirmed: if banks compounded annually, the long-tenure rows would diverge by hundreds of basis points, and they do not.
Rows are ordered by published nominal rate and by nothing else — no safety rating, no sponsorship, no recommendation about which institution to choose. Where a bank publishes a separate senior-citizen rate it is used; where it does not, the standard rate is shown and flagged as such rather than quietly inflated. Each row also carries the minimum deposit the bank states, the effective date it stamps on the sheet, and a link to that sheet, so any figure on this page can be checked against its source in one tap.
Two benchmarks frame the table. The Central Bank's AWFDR covers the whole outstanding deposit book, so it lags what is on offer today; its AWNFDR series, covering new deposits only, is the fairer comparison. And the deposit insurance limit of Rs 1,100,000applies per depositor per institution, principal and accrued interest together — which is why the page warns the moment a deposit's maturity value crosses it.
Worked examples
What each bank publishes
Rate transparency varies more than the rates themselves. This is what each institution disclosed when the snapshot was taken on 2026-09-22.
| Institution | Type | Effective date | Published rate rows |
|---|---|---|---|
| Bank of Ceylon | State | Effective from 08.06.2026 | 15 |
| People's Bank | State | w.e.f. 09 June 2026 | 15 |
| National Savings Bank | State | W.E.F. 02/06/2026 | 13 |
| Commercial Bank of Ceylon | Commercial | no effective date shown on the LKR deposit table | 13 |
| Hatton National Bank | Commercial | last reviewed 11.09.2026 | 15 |
| Seylan Bank | Commercial | w.e.f. 22.07.2026 | 26 |
| National Development Bank | Commercial | last updated 24.08.2026 | 15 |
| Nations Trust Bank | Commercial | rate sheet updated 15.09.2026 | none |
| Sampath Bank | Commercial | no machine-readable rate sheet | none |
| DFCC Bank | Commercial | no machine-readable rate sheet | none |
7 of 10 listed institutions publish usable rupee fixed deposit rates. A rate row is one tenure at one payout mode for one depositor class, so a bank with a separate senior-citizen table carries more rows than one without. The three institutions with none are listed with the reason rather than dropped, because knowing a bank will not show you its rate online is worth knowing before you telephone a branch.
