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 much you want to place in one deposit, at one bank. Every rupee figure below is computed on this amount.

Quick amounts
Tenure
Interest paid

Interest accrues and is paid in one sum with the principal at the end of the term.

Depositor
Advance Income Tax (AIT)

Banks deduct 10% of gross interest at source. For a resident, that is an advance credited against your final tax bill, not a final tax.

A beside an AER means the figure computed here matches the one the bank prints on its own sheet. Rupee amounts are net of AIT where you asked for it, and exclude any account fee.

Not published for this tenure and payout

  • Nations Trust Bank Nations Trust publishes a dated interest-rate sheet covering savings, call and money-market deposits, but it lists no rupee fixed-deposit rates at all. The rate is quoted at a branch.
  • Sampath Bank Sampath's deposit rates render only inside a client-side viewer on its rates page, and no downloadable rate sheet was published when this snapshot was taken. Rather than copy the figures from an aggregator, this table carries none. Check the bank's own page.
  • DFCC Bank DFCC publishes a downloadable savings-account rate sheet but no equivalent for rupee fixed deposits; the FD figures load only inside its rates viewer. No number is carried here without a readable source.

A higher rate is not always more money

Rs 1,000,000 · 10.00% · at maturity

Rs 100,000 gross interest · AER 10.00%

Rs 1,000,000 · 9.75% · paid monthly

Rs 97,500 gross interest · AER 10.20%

The monthly deposit pays Rs 2,500 less cash over the year, yet its effective rate is higher — because each Rs 8,125 payment can be put back to work for the rest of the year. That AER only exists if you actually reinvest it. If you live on the monthly interest, the number that matters to you is the 9.75%, not the 10.20%.

Against the marketThe Central Bank's average weighted fixed deposit rate (AWFDR) for July 2026 was 9.20%. Commercial's 10.00% sits +0.80 pp above it. New deposits opened that month averaged 8.83%.

Deposit insurance

At maturity this deposit would be worth Rs 1,090,000, which sits inside the Rs 1,100,000 compensation limit — principal and accrued interest together are covered at this institution.

Sources cited.Every rate above comes from the named bank's own website, read on 2026-09-22; tap a bank to open the sheet it came from. The oldest effective date in this table is 2026-06-02. Market benchmarks are the Central Bank of Sri Lanka's AWFDR and AWNDR for July 2026. The 10% AIT and the Rs 1,100,000 deposit-insurance limit come from the Inland Revenue Department and the Central Bank respectively.

Verified maths. The effective-rate formulas on this page reproduce 91 of the 91 AER figures these banks print on their own rate sheets, the worst gap being 2.24 basis points. Banks change rates without notice — confirm at the branch before you deposit. This is information, not advice, and no bank here is recommended over another.

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.

  1. 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.
  2. Monthly-payout deposits pay P × r ÷ 12 each month and return the principal untouched at the end. Nothing compounds inside the deposit.
  3. 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.
  4. 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

Rs 1,000,000 for 12 months at 10.00%, paid at maturity

Commercial Bank, HNB, NDB and Seylan all publish this rate

  1. Gross interest: Rs 1,000,000 × 10.00% × 1 year = Rs 100,000
  2. Advance Income Tax: 10% × Rs 100,000 = Rs 10,000
  3. Net interest: Rs 100,000 − Rs 10,000 = Rs 90,000
  4. Paid at maturity: Rs 1,000,000 + Rs 90,000 = Rs 1,090,000
  5. AER: (1 + 0.10 × 1)^(1/1) − 1 = 10.00% — at exactly one year the effective rate equals the nominal rate
  6. After tax: (1 + 0.09)^(1/1) − 1 = 9.00%

Rs 1,000,000 for 12 months at 9.75%, paid monthly

The comparison that justifies this page

  1. Monthly gross: Rs 1,000,000 × 9.75% ÷ 12 = Rs 8,125.00
  2. Monthly AIT: 10% × Rs 8,125.00 = Rs 812.50
  3. In your account each month: Rs 7,312.50
  4. Over twelve months: gross Rs 97,500 · AIT Rs 9,750 · net Rs 87,750
  5. AER: (1 + 0.0975 ÷ 12)^12 − 1 = (1.008125)^12 − 1 = 10.20%
  6. So this deposit pays Rs 2,500 LESS cash than the 10.00% one above…
  7. …yet carries the HIGHER effective rate — but only if every Rs 8,125 is reinvested at 9.75%.
  8. Spend the monthly interest and you earn 9.75%, not 10.20%.

Rs 2,000,000 for 12 months at 8.50%, paid monthly, self-declaration filed

Edge case — no AIT deducted, and above the deposit insurance limit

  1. Monthly gross: Rs 2,000,000 × 8.50% ÷ 12 = Rs 14,166.67
  2. Self-declaration on file (assessable income ≤ Rs 1,800,000): AIT = Rs 0
  3. In your account each month: Rs 14,166.67
  4. Over twelve months: Rs 170,000 interest, none of it withheld
  5. AER: (1 + 0.085 ÷ 12)^12 − 1 = 8.84%
  6. Had AIT been deducted: Rs 12,750.00 a month and Rs 153,000 for the year
  7. Deposit insurance: Rs 2,000,000 exceeds the Rs 1,100,000 limit, leaving Rs 900,000 uninsured at that one bank

What each bank publishes

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.
