Murabaha Calculator

What Murabaha is

Murabaha is an Islamic-finance structure where the financier purchases an asset on the customer's behalf and resells it at an agreed marked-up price payable in instalments. Because the contract is structured as a sale of a real asset rather than a loan with interest, the mark-up is classified as profit and the contract complies with Sharia prohibitions on riba (interest). The profit component is fixed at signing — it doesn't compound on a declining balance — and the customer pays equal monthly instalments for the duration of the term.

How to use it

Enter the principal (asset cost being financed), the annual flat profit rate from the contract, and the term in years. The calculator returns the total contract amount, the profit component, the monthly instalment, the stated flat profit rate, an APR-equivalent expressed as a declining-balance rate for comparison with conventional financing, and the contract term. The currency selector at the top of the calculator changes formatting throughout — the math itself is currency-neutral.

How Murabaha differs from conventional loans

A conventional loan charges interest on the declining outstanding balance — early payments are mostly interest, late payments mostly principal, and total interest depends on the amortisation schedule. Murabaha applies a flat profit rate to the original principal across the full term — total profit is fixed at signing and doesn't change as the balance falls. The customer pays equal monthly instalments throughout. Structurally these are different contracts; numerically the flat-rate Murabaha typically produces a higher total cost than a conventional loan at the same headline rate, because the flat rate doesn't benefit from the declining-balance reduction.

Worked example

Picture a 200,000 principal at a 5% flat profit rate over 5 years (currency follows the selector). Total profit = 200,000 × 5% × 5 = 50,000. Total contract amount = 200,000 + 50,000 = 250,000. Monthly instalment = 250,000 ÷ 60 ≈ 4,166.67. Profit as a percentage of principal = 25%. Stated flat profit rate is 5%; the APR-equivalent for the same monthly payment under standard declining-balance amortisation is about 9.15% — meaningfully higher than the headline 5%, because the flat rate applies to the original principal each year rather than to the declining outstanding balance. This is the gap to keep in view when comparing Murabaha against conventional financing on a like-for-like basis.

Why the APR-equivalent matters

The two rates describe the same total cost in different ways. The stated profit rate (5% in the example) is what's written in the Murabaha contract; the APR-equivalent (≈9.15%) is what a conventional declining-balance loan would need to charge to produce the same monthly payment over the same term. Comparing a 5% Murabaha against a conventional offer at "5% APR" is not like-for-like — the conventional offer at the same headline rate would actually be cheaper because conventional interest accrues on a falling balance. Surfacing both rates makes the comparison transparent.

How the math works

Total profit = principal × profit rate ÷ 100 × years (flat-rate calculation). Total contract = principal + total profit. Monthly instalment = total contract ÷ (years × 12). Profit % of principal = total profit ÷ principal × 100. APR-equivalent is found numerically: the calculator solves the standard amortisation formula for the rate that produces the same monthly payment on the same principal and term.

Where Murabaha typically applies

Common applications include home financing (often combined with diminishing Musharaka in some markets), car finance, business equipment, and consumer-goods financing through Islamic banks. Specific availability and rate offerings depend on the lender's product catalogue and the customer's eligibility. Specific rate ranges vary by country, regulator, and provider type — published market data is available from organisations like the Islamic Financial Services Board, while specific offers are quoted by individual lenders. Use the rate quoted on the actual contract rather than category averages for any specific calculation.

Early repayment in Murabaha

Because total profit is set at contract signing rather than calculated on a declining balance, early repayment doesn't automatically reduce the total cost the way it does on a conventional amortising loan. Some Murabaha contracts include a discretionary discount provision (Ibra) where the lender may rebate part of the unearned profit on early repayment, but this isn't a contractual right under standard Murabaha. The specific terms appear in the contract; comparing whether early-repayment discount is offered is one of the practical differences when comparing Murabaha against conventional alternatives.

Variations in Murabaha structure

Standard Murabaha uses fixed flat-rate profit with equal instalments (the structure modelled by this calculator). Diminishing Musharaka combines Murabaha-like elements with co-ownership where the bank's share reduces over time. Bullet-payment Murabaha pays the total contract at the end of term rather than in instalments. Working-capital Murabaha uses commodity transactions for short-term financing. The calculator models the standard equal-instalment case; AAOIFI Shariah Standard 8 documents the contractual conditions for compliant Murabaha and notes the variations.

What this calculator doesn't capture

Specific Sharia-compliance certification (which scholar bodies have approved a particular product), discretionary early-repayment discount (Ibra) policies that vary by lender, late-payment treatment under Sharia principles, takaful (Islamic insurance) premiums that some contracts bundle, arrangement and documentation fees, country-specific tax treatment of Islamic-finance products, and contract variations like diminishing Musharaka or bullet repayment. The figures are an estimate of the headline contract cost based on the three inputs entered.
