Murabaha and conventional loans can quote the same percentage yet cost wildly different totals, because one charges interest on a declining balance while the other fixes a markup on the original amount. This calculator runs both structures side by side — monthly payment, total cost of credit, and total payable — so the comparison is apples to apples.
How the Two Structures Differ
Conventional loan. You borrow principal and pay interest on whatever balance remains. Early payments are mostly interest; as the balance falls, so does each month's interest charge. The monthly payment follows the standard amortization formula:
Murabaha. The financier buys the asset itself, then sells it to you at a disclosed markup, payable in instalments. There is no interest on a declining balance — the profit is fixed at signing as a simple product:
During the sale the financier genuinely owns the asset and bears its risk, which is what distinguishes the structure in Sharia terms; late-payment amounts, where they exist, typically cannot become the financier's income.
| Input | Meaning | | --- | --- | | Financing amount | The asset price / principal to compare | | Term (years) | Defaults to 30 if left blank | | Conventional rate | Annual interest rate of the amortizing loan (default 6.52%) | | Profit rate | Annual Murabaha markup rate (defaults to the conventional rate) | | Early payoff flag | Surfaces the early-settlement warning described below |
Worked Example — Same Rate, Different Cost
Finance $300,000 over 30 years at 6.5% under both structures:
| | Conventional | Murabaha | | --- | --- | --- | | Monthly payment | 2,458.33 | | Total interest / profit | 585,000 | | Total payable | 885,000 |
The Murabaha costs **300,000 for all 30 years, while the loan's 6.5% is charged on a balance that shrinks monthly. Put differently, this Murabaha's payment stream is economically equivalent to a conventional loan at an APR of about 9.2%. That implied-rate translation is the fairest single number for comparing offers across structures: ask what conventional APR would produce the same payment on the same principal.
The Early-Settlement Trap
The sharpest practical difference appears if you sell or refinance early. On a conventional loan, interest stops when the balance is repaid — settle in year 5 and you never pay years 6–30 of interest. In a strict Murabaha, the sale price (including all 30 years of profit) was fixed at signing, so early settlement may still owe the full amount unless the contract grants a rebate — ibra' — which many providers offer by policy or regulation but which is not guaranteed in every contract. Tick the early-payoff option and this calculator displays the warning; before signing anything, get the rebate terms in writing.
Reading the Result Fairly
The calculator declares a winner on total cost and shows the difference. Total cost is not the only legitimate criterion: the Murabaha payment is fixed and certain for the full term, immune to rate rises that would hit a variable-rate loan, and for many buyers the structure's compliance with their faith is the point of the product — a reason, not an oversight. Compare like with like (fixed vs fixed rate, same term, fees included), translate markups into implied APRs, and weigh certainty and compliance alongside the headline total.
Limitations
This is an educational model of a simple Murabaha: real contracts may use declining-balance profit calculations (as in diminishing musharakah), tiered rates, fees, insurance (takaful) costs, and regulated rebate formulas that change the totals. It is not a fatwa, a contract review, or financial advice.
Frequently Asked Questions
Why does the same rate cost more under Murabaha?
Because the bases differ. Interest accrues on the outstanding balance, which falls every month; the classic Murabaha markup accrues on the original amount for the whole term. Equal rates on unequal bases cannot produce equal costs.
How do I compare a Murabaha quote with a loan quote fairly?
Convert the Murabaha to its implied APR: find the amortizing-loan rate whose payment equals the Murabaha payment on the same amount and term. In the worked example, a 6.5% markup equals roughly a 9.2% APR — compare that with loan APRs, fees included.
Is a rebate (ibra') guaranteed if I settle early?
No. Practice varies by provider, contract, and jurisdiction — some regulators require a rebate formula, others leave it discretionary. The calculator flags this precisely because it can be worth tens of thousands; verify it in the contract before signing.
