Rental Yield in Sri Lanka: What Landlords Should Actually Measure
Reviewed and updated July 16, 2026 · Written for Sri Lankan investors and borrowers
Sri Lankan property investors often quote the rent a unit “can fetch” without ever converting it into a yield they can compare against alternatives. That is a costly habit, because the alternatives here are unusually strong: fixed deposits and Treasury bills frequently pay high nominal rates, and they require no tenants, no repairs and no lawyers. A rental property has to clear that bar after all its costs to justify the effort.
This guide explains gross yield, net yield and cap rate in plain terms, shows the deductions most landlords forget, and covers the tax treatment of rental income for resident individuals so you can compare property against financial assets on a genuinely level field.
Gross yield: the headline number
Gross rental yield is simply annual rent divided by the property’s value. A Rs 30 million apartment renting at Rs 150,000 a month collects Rs 1.8 million a year, for a gross yield of 6 percent. Gross yield is useful for quick screening and for comparing similar units in the same neighbourhood, but it is not money you can spend, because none of the costs of ownership have been deducted yet.
As a rule of thumb, Colombo apartments often show gross yields well below what FDs pay, which means investors there are really betting on capital appreciation rather than income. Units in secondary cities and suburbs can show higher gross yields but usually carry more vacancy and tenant risk.
Net yield: what you actually keep
Net yield deducts the real costs of being a landlord. Continuing the example: one month of vacancy costs Rs 150,000, condominium management fees of Rs 20,000 a month cost Rs 240,000 a year, and repairs, insurance and rates might add Rs 110,000. Net income falls from Rs 1,800,000 to Rs 1,300,000, and net yield drops from 6 percent to about 4.3 percent. That 1.7 percentage point gap is typical, and ignoring it flatters property badly in any comparison.
Cap rate is the commercial cousin of net yield: net operating income divided by property value, before financing costs. It lets you compare properties independent of how each buyer funds the purchase. If you borrow to buy, also check that net rent covers the loan instalment, because negative monthly cash flow has sunk many small landlords.
| Item | Amount per year |
|---|---|
| Gross rent (12 months) | Rs 1,800,000 |
| Vacancy (1 month) | minus Rs 150,000 |
| Management fees (Rs 20,000 monthly) | minus Rs 240,000 |
| Repairs, insurance, rates | minus Rs 110,000 |
| Net operating income | Rs 1,300,000 |
| Net yield on Rs 30 million | about 4.3 percent |
Tax on rental income: the 25 percent rent relief
Under current rules, resident individuals receiving rental income can claim rent relief of 25 percent of that rental income, meaning only 75 percent of the rent enters their taxable income, where it is taxed at the normal progressive slabs of 6 to 36 percent after the Rs 1.8 million personal relief. On Rs 1.8 million of annual rent, relief of Rs 450,000 leaves Rs 1,350,000 taxable. Your actual tax depends on your other income and which slab the rent lands in, so verify your position with the Inland Revenue Department or a tax adviser.
Comparing yield against FDs and T-bills
The fair comparison is after-tax net rental yield against after-tax FD or T-bill returns. Interest income carries a 10 percent advance income tax deducted at source, while rental income flows through your progressive slabs after the 25 percent relief. Property adds illiquidity, tenant risk and concentration in a single asset, but also offers potential capital appreciation and rents that can rise with inflation, which fixed-rate deposits cannot.
A sensible framing: if a property’s net yield sits far below deposit rates, you are paying for an appreciation bet, so make that bet consciously. If net yield is competitive with deposits and the location has genuine rental demand, the income case can stand on its own.
Using the calculator
Enter realistic vacancy, management and maintenance figures rather than zeros, and use the price you would actually pay today, including stamp duty and legal costs, as the denominator. Recalculate yearly, because a property that yielded well at your purchase price may compare poorly against today’s alternatives at today’s market value.
