Key things to know
- Housing-loan rates track the CBSL Overnight Policy Rate (7.75%) plus a bank spread, so most sit around 10–12% as the economy stabilizes post-crisis.
- Tenures run up to 20–25 years; a longer tenure lowers the installment but raises total interest sharply.
- Many banks offer fixed-for-a-period then variable structures — check when and how your rate can reprice.
Frequently Asked Questions
How is a housing loan installment calculated in Sri Lanka?
Using the reducing-balance formula P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1). Most loans are variable, repricing as the CBSL policy rate changes.
What is the current housing loan rate in Sri Lanka?
Roughly 10–12% per year in 2026, reflecting the CBSL OPR of 7.75% plus a spread. Commercial Bank, HNB, Sampath, BOC and NDB are major lenders.
What is the maximum tenure?
Usually up to 20–25 years, subject to your age at maturity and income. A longer tenure reduces the monthly installment but increases total interest.
Are fixed-rate housing loans available?
Many banks offer a fixed rate for an initial period (e.g. 1–5 years), then switch to a variable rate. Confirm the reprice timing and the variable formula before signing.
Can I prepay my housing loan?
Yes. Partial prepayments early in the term remove large amounts of interest. Check your bank's early-settlement charge first.
