Loan instalment calculator

General estimate; fees and insurance excluded. The bank’s offer is binding. The equivalent APR shows the real cost of a flat rate.

Flat-rate instalment = (amount + amount × rate × years) ÷ months. Enter the amount, rate and term above and choose the method to see the monthly instalment, the total repaid, the total profit and the equivalent APR, which shows the real cost of the flat rates quoted in Saudi personal finance offers.

How to use the loan calculator

Enter the loan amount in riyals.
Enter the annual rate from the bank's offer and the term in months (60 months maximum for consumer finance).
Choose flat rate (common for personal finance) or reducing balance (APR).
Compare the instalment with 33.33% of your salary and check total profit and APR before signing.

Flat rate vs reducing balance

Flat: profit is charged on the full amount for the whole term, even after you have repaid most of it, so the headline rate looks low.
Reducing (APR): profit is charged monthly on the remaining balance only, as with mortgages.

Rule of thumb: the APR equivalent of a flat rate is close to double over medium terms, which is why the Saudi Central Bank requires lenders to disclose the APR.

Worked examples (riyals)

Flat: 100,000Saudi riyal at 5% for 60 months: profit 100,000 × 5% × 5 = 25,000Saudi riyal; total 125,000Saudi riyal; instalment 2,083.33Saudi riyal; equivalent APR ≈ 9.15%.

Reducing: same amount at 5% APR for 60 months: instalment 1,887.12Saudi riyal; profit only 13,227.40Saudi riyal.

Amount	Flat rate, term	Instalment	Total profit	Equivalent APR
50,000	4%, 36 months	1,555.56	6,000	7.51%
100,000	5%, 60 months	2,083.33	25,000	9.15%
200,000	3.5%, 60 months	3,916.67	35,000	6.54%

Admin fees (capped by the central bank) and insurance are not included.

Debt buy-out and refinancing

A debt buy-out moves your existing finance to a new bank on new terms. Compare the outstanding amount, the new offer's APR, the new term and the fees. A longer term lowers the instalment but raises total profit, so try both cases in the calculator before deciding.

Saudi Central Bank limits

Salary cap: consumer finance instalments may not exceed 33.33% of gross salary for employees and 25% for retirees (Responsible Lending Principles); the overall cap is higher when a mortgage is involved.
Term: consumer finance up to 60 months.
Early repayment: allowed in full or in part; the lender may charge only the outstanding amount plus a capped reinvestment cost (at most three months' profit for consumer finance).

A 12,000Saudi riyal salary allows consumer-finance instalments of up to about 4,000Saudi riyal a month, including existing ones.

Shorter terms cut profit sharply: 100,000 at 5% flat costs 15,000 over 36 months versus 25,000 over 60. Plan instalments around your salary date.

Loan calculator FAQ

How is a personal loan instalment calculated?

At a flat rate: profit = amount × rate × years, then instalment = (amount + profit) ÷ months. 100,000 at 5% for five years is 2,083.33 a month.

What is the difference between flat and APR?

Flat charges profit on the full amount for the whole term; APR charges it on the remaining balance, so it is cheaper at the same rate.

What is the maximum deduction from salary in Saudi Arabia?

33.33% of gross salary for employees and 25% for retirees for consumer finance, per the central bank's principles.

What is the maximum personal finance term?

60 months for consumer finance.

Does the calculator include fees?

No; it covers principal and profit only. Add admin fees and insurance from the bank's offer.
