How much loan can I get on my salary?
How much you can borrow depends on three things: the monthly repayment you can commit to, the interest rate and the loan term. Each bank sets its own limit on how much of your income can go to repayments. So decide your repayment first, then turn it into a loan amount with the calculator above.
Worked example: Rs. 40,000 salary
Say your salary is Rs. 40,000. After rent, food and other bills, you decide Rs. 12,000 a month (30%) can go to a loan. The share is your choice. Pick what your budget allows.
At an example rate of 12% a year over 5 years (60 months):
- Monthly rate r = 12% ÷ 12 = 1% = 0.01
- (1 + r)^60 = 1.01^60 ≈ 1.8167
- Loan amount = Rs. 12,000 × (1.8167 - 1) ÷ (0.01 × 1.8167) ≈ Rs. 12,000 × 44.955 ≈ Rs. 539,460
- You repay Rs. 12,000 × 60 = Rs. 720,000, so total interest is about Rs. 180,540.
Rs. 40,000 salary: loan amount by repayment share and term (example rate 12% p.a.)
| Share of salary you choose | Monthly repayment | 3 years | 5 years | 7 years |
|---|---|---|---|---|
| 20% | Rs. 8,000 | Rs. 240,860 | Rs. 359,640 | Rs. 453,188 |
| 25% | Rs. 10,000 | Rs. 301,075 | Rs. 449,550 | Rs. 566,485 |
| 30% | Rs. 12,000 | Rs. 361,290 | Rs. 539,460 | Rs. 679,781 |
12% is an example rate, not a bank rate. Change the rate and term in the calculator to match a real quote. If EPF and other deductions come out of your salary, use the amount you actually receive. The EPF and ETF calculator shows your pay after the 8% EPF deduction.
How Sri Lankan Loan Repayments are Calculated
Personal, vehicle and housing loans in Sri Lanka are commonly quoted using the reducing-balance equated monthly instalment (EMI) method. Some products, such as leasing, may be quoted at a flat rate instead. Always check which method a quote uses.
Under this method, the periodic repayment amount (M) remains fixed throughout the loan term, while the proportion allocated to interest decreases each month as the outstanding capital is paid down:
Where:
- P (Principal): The total initial loan amount borrowed in Sri Lankan Rupees (LKR).
- r (Periodic Interest Rate): The nominal annual interest rate divided by 12 and converted to a decimal:
r = (Annual Rate % / 12 / 100). - n (Number of Payments): The total repayment periods in months (e.g. 5 years = 60 months).
For borrowing affordability, the inverse present-value formula calculates the maximum loan principal (P) supportable by a target monthly repayment (M):
Worked Calculation Example
Consider a typical Sri Lankan personal or vehicle financing scenario calculated with the pure mathematical engine:
| Input Parameter | Example Value | Formula Variable |
|---|---|---|
| Loan Amount (Principal) | Rs. 1,000,000 | P = 1,000,000 |
| Annual Interest Rate | 12.00% per annum | r = 0.12 / 12 = 0.01 per month |
| Loan Duration (Term) | 5 Years (60 Months) | n = 60 |
Resulting Repayment Breakdown:
Applying the reducing-balance calculation engine:
- Estimated Monthly Repayment (EMI): Rs. 22,244.45 per month
- Total Repayment Amount: Rs. 1,334,666.86 over 60 months
- Total Interest Payable: Rs. 334,666.86
- Repayment Ratio: 74.9% Principal vs 25.1% Interest
In the first month, your payment of Rs. 22,244.45 is Rs. 10,000.00 interest and Rs. 12,244.45 principal. By month 60, the interest part falls to Rs. 220.24. The remaining Rs. 22,024.21 clears the final balance.
Flat rate vs reducing balance: worked comparison
A flat rate charges interest on the full loan amount for the whole term. A reducing-balance rate charges interest only on what you still owe. So the same headline rate costs much more on a flat basis. On Rs. 1,000,000 over 5 years, 12% flat costs about the same as 20.3% on a reducing balance.
Same loan, two methods: Rs. 1,000,000 over 5 years (60 months) at 12%
| 12% reducing balance | 12% flat rate | |
|---|---|---|
| How interest is worked out | 1% a month on the balance still owed | 12% × Rs. 1,000,000 × 5 years = Rs. 600,000 |
| Monthly instalment | Rs. 22,244.45 | Rs. 1,600,000 ÷ 60 = Rs. 26,666.67 |
| Total interest | Rs. 334,666.86 | Rs. 600,000.00 |
| Total repaid | Rs. 1,334,666.86 | Rs. 1,600,000.00 |
| Same as a reducing-balance rate of | 12% | about 20.3% |
The flat-rate loan costs Rs. 4,422.22 more each month and Rs. 265,333.14 more interest over 5 years.
The equivalent rate depends on the term
The conversion isn’t a fixed multiple. For the same 12% flat rate on Rs. 1,000,000:
| Term | Flat-rate monthly instalment | Flat-rate total interest | Same as a reducing-balance rate of about |
|---|---|---|---|
| 1 year | Rs. 93,333.33 | Rs. 120,000 | 21.5% |
| 3 years | Rs. 37,777.78 | Rs. 360,000 | 21.2% |
| 5 years | Rs. 26,666.67 | Rs. 600,000 | 20.3% |
| 7 years | Rs. 21,904.76 | Rs. 840,000 | 19.5% |
So always quote the term with any flat-to-reducing comparison. To compare two quotes fairly, ask each lender for the reducing-balance (effective) rate. Or compare the monthly instalment and total interest for the same amount and term.
Evaluating Loan Term Trade-offs
When choosing a repayment duration in Sri Lanka, borrowers face a fundamental financial trade-off:
- Shorter Terms (e.g. 2 to 3 Years): Require higher monthly instalments (which demands more immediate cash flow), but significantly cut the total interest paid to the lender.
- Longer Terms (e.g. 5 to 10+ Years): Lower the monthly commitment, giving your budget more breathing room, but substantially raise the cumulative interest bill over the life of the loan. Lenders separately assess your overall debt commitments, verified income, employment, credit history, and internal eligibility criteria.
Always compare the total interest payable across a few different tenures before locking in a financing contract.
How to compare loan quotes
We don’t list bank rates, because they differ by lender and change often. To compare real offers, ask two or three lenders for a written quote on the same amount and term. Then check each quote against this list and put the numbers into the calculator above.
- Rate method: Is the rate reducing balance or flat? If it’s flat, ask for the reducing-balance (effective) rate. See the worked comparison.
- Fixed or floating: Is the rate fixed, or linked to a benchmark such as AWPLR? If it floats, ask what margin is added and how often it resets.
- Upfront fees: processing and documentation charges.
- Government and legal costs: stamp duty, plus legal and valuation fees for a housing loan.
- Insurance: whether credit life or property insurance is required, and who pays for it.
- Early settlement: whether there is a charge for paying off early or paying extra.
- Total cost: monthly instalment × number of months, plus all upfront costs. The lowest total wins, not the lowest headline rate.
Personal, housing and vehicle loans (and leasing)
Personal loan
Usually unsecured or backed by a salary assignment. Used for home improvements, family needs or paying off other debts. Example: Rs. 500,000 over 3 years at an example rate of 12% is Rs. 16,607.15 a month, with Rs. 97,857.58 total interest.
Housing / home loan
Housing loans run over long terms, so a small rate difference adds up. Example: Rs. 5,000,000 over 20 years at 12% is Rs. 55,054.31 a month. At 12.5%, it is Rs. 56,807.03 a month. That is Rs. 1,752.72 more each month and Rs. 420,653.00 more interest over 20 years. Buying land first? Check the plot’s size with our perch to square feet converter.
Vehicle leasing
In Sri Lanka, vehicle finance is often called leasing. Leasing quotes are often given as a flat rate. A flat rate looks cheaper than the same reducing-balance rate but costs more. Before you compare a lease with a bank loan, see the flat rate vs reducing balance worked comparison.
Some lenders offer a balloon (residual) payment: a lump sum left owing at the end, paid with the last instalment. It lowers the monthly payment but raises the total interest. On Rs. 5,000,000 over 5 years at 12%, a Rs. 1,000,000 balloon cuts the instalment from Rs. 111,222.24 to Rs. 98,977.79, but total interest rises from Rs. 1,673,334.31 to Rs. 1,938,667.44. To model one, open More options in the calculator above.
Some lenders also collect the first lease rental upfront, which they may call a “1+0” basis. Commercial Bank’s leasing calculator, for example, gives its results on that basis. Each rental is then slightly lower than a loan repaid at the end of each month: Rs. 110,121.03 instead of Rs. 111,222.24 on the same Rs. 5,000,000 over 5 years at 12%. To match such a quote, tick First instalment paid upfront under More options.

How much of a vehicle can be financed? (Central Bank limits from 25 May 2026)
The Central Bank caps how much licensed banks, licensed finance companies and registered leasing companies can lend against a vehicle. The cap covers leases, hire purchase and vehicle loans, and applies from 25 May 2026.
| Vehicle | Maximum loan, as a share of the vehicle’s value |
|---|---|
| Registered and used in Sri Lanka for more than 1 year (any vehicle) | 60% |
| Brand-new, reconditioned, or registered for less than 1 year: commercial vehicles (DMT classes C1, C, CE, D1, D, DE, G1, G, J, and light trucks and single cabs under B) | 60% |
| Brand-new, reconditioned, or registered for less than 1 year: cars, SUVs, vans, three-wheelers and any other vehicle (DMT classes B, B1, A1, A) | 40% |
Example: a brand-new car valued at Rs. 10,000,000 can be financed up to Rs. 4,000,000, so you’d need Rs. 6,000,000 of your own. Borrowing that Rs. 4,000,000 over 5 years at an example rate of 12% is Rs. 88,977.79 a month.
How the value is set: market value. For a brand-new vehicle, lenders can use the value confirmed by the authorised agent. For a reconditioned vehicle, the valuation at Customs clearance or the dealer’s invoice. For a used vehicle, a professional valuer’s report.
