Business loan affordability Sri Lanka: AWPR and debt cover

Last verified against the primary sources on 15 October 2026.

Before you walk into a bank, you should know three numbers: the monthly repayment, the total interest over the life of the loan, and whether your business can carry the repayment. You can work out the first two in our business loan calculator; this guide explains how to read them and how to test the third.

What is AWPR and why it matters for your loan

The Average Weighted Prime Lending Rate (AWPR) is the benchmark rate the Central Bank of Sri Lanka publishes weekly in its Weekly Economic Indicators [1]. Banks price business lending at a margin above their prime rates, and the margin depends on your credit profile, collateral and sector.

The weekly AWPR was 11.16% in the week to 9 October 2026, and the Central Bank's Overnight Policy Rate stood at 8.75%, against 7.75% a year earlier [1]. Rates have been moving up over the past year, not down, so build that into your planning.

If you have not yet received a formal quote from your bank, use the latest AWPR plus a margin of a few percentage points as a cautious planning figure, then replace it with the bank's rate once you have one.

Step by step: working out the repayment

Step 1. The loan amount. The amount you intend to borrow in LKR. Each bank sets its own minimum and maximum for business facilities; ask before you apply.

Step 2. The interest rate. Use your bank's quoted rate. If you do not have one yet, use the planning figure above.

Step 3. The tenure. Short-term working capital loans often run 12 to 36 months. Equipment and other capital expenditure finance often runs longer. Property loans can run ten years or more.

Step 4. The output. You want the monthly repayment, the total interest payable, the total repaid (principal plus interest), and how each payment splits between principal and interest.

Understanding debt serviceability

Knowing your monthly repayment is step one. Knowing whether your business can service it is the more important question.

Debt Service Coverage Ratio (DSCR)

Banks will look at your DSCR before approving a loan:

DSCR = Net Operating Income / Total Debt Service

A ratio below 1.0 means operating income does not cover the debt payments. Each bank sets its own minimum above that, so ask yours what it requires.

Example. Take a hypothetical business with LKR 3,000,000 of monthly net operating income, considering a LKR 20,000,000 loan at 14% per annum over 60 months.

• Monthly repayment: approximately LKR 465,000
• DSCR: 3,000,000 / 465,000 = 6.45

At 6.45x the repayment is comfortably covered by operating income.

Now a tighter scenario: LKR 20,000,000 at 14% over 36 months.

• Monthly repayment: approximately LKR 683,000
• DSCR: 3,000,000 / 683,000 = 4.39

Still well covered, but the shorter tenure increases monthly pressure considerably.

Analysis before you borrow

Sensitivity to rate increases. Sri Lanka's interest rates have been volatile. Work out your repayments at your quoted rate plus 2% and plus 4% to see your exposure if rates rise, especially on a floating rate facility.

Impact on working capital. A monthly repayment reduces the cash available to run the business. Confirm you can absorb it in low-revenue months. If your revenue is seasonal, as is common in tourism, retail and agriculture, test the worst trading month against the repayment.

Tax deductibility. Interest on money borrowed for the business is generally deductible in working out business income, subject to the limits in the Inland Revenue Act No. 24 of 2017 [2]. At the standard corporate rate of 30% [2], an interest rate of 14% has an after-tax cost of about 9.8%, provided the company has taxable profits to set the interest against.

Opportunity cost. Compare the expected return on what you are financing with the all-in cost of the loan. If a new machine adds LKR 200,000 a month in margin and costs LKR 100,000 a month to finance, the net contribution is positive. If the numbers are marginal, reconsider the investment.

What a repayment figure leaves out

A repayment worked out from amount, rate and tenure does not include:

• Establishment fees, documentation charges or valuation fees that banks add to the upfront cost
• Collateral requirements or personal guarantees
• Revolving facilities, where the outstanding balance changes month to month
• The judgement needed for complex borrowing structures

For large loans, or where the financing is part of a wider capital structure decision, get professional advice before you sign.
