Loan & EMI Calculator
Monthly instalment, total interest and full cost of a personal or auto loan — and what a quoted flat rate actually costs on a reducing balance.
Loan & EMI Calculator
Monthly instalment, total interest, and what a flat rate really costs.
Method. On a reducing balance the instalment is the standard amortising payment, with interest charged only on the outstanding balance. On a flat rate, interest is charged on the full original amount for the entire term; the effective rate shown is the reducing-balance rate that produces the same instalment.
Compare offers on the effective reducing rate and the total repayable, never on the headline flat rate. Fees and mandatory insurance frequently add more than a rate difference does.
| Quoted as | Interest charged on | Roughly equivalent to | What to compare |
|---|---|---|---|
| Flat rate | The full original principal, for the whole term | Close to double the same figure on a reducing balance | Total repayable, and the effective reducing rate |
| Reducing balance | The outstanding balance only, month by month | The rate as stated | The rate itself, plus fees |
Flat rate and reducing balance are not comparable
Gulf banks routinely advertise personal and auto finance at a flat rate, and the number looks attractive precisely because it is not what it appears to be. A flat rate charges interest on the full original principal for the entire term, even as you repay and the balance falls. A reducing-balance rate charges interest only on what is actually outstanding. The same borrowing quoted at a given flat rate typically costs close to double the equivalent reducing-balance rate — which is why this tool converts one into the other rather than treating them as alternatives.
What the instalment leaves out
The monthly figure is the easy part of a loan and rarely the expensive part. Arrangement and processing fees, mandatory life cover, and early-settlement charges all sit outside the instalment and frequently cost more than the difference between two lenders' rates. When comparing offers, compare the total repayable over the full term with every fee added, not the headline rate and not the monthly payment in isolation — a longer term always produces a smaller instalment and a larger total.
Common questions
What is a flat rate?
A rate charged on the full original loan amount for the whole term, regardless of how much you have repaid. Because your balance falls but the interest charge does not, the effective cost is far higher than the quoted figure — usually close to twice the equivalent reducing-balance rate.
How should I compare two loan offers?
On the total repayable over the full term, with every fee and any mandatory insurance included, and on the effective reducing-balance rate. Never on the headline rate alone, and never on the monthly instalment alone, since stretching the term lowers the instalment while raising the total.
Does settling early save interest?
On a reducing-balance loan, substantially — interest stops accruing on the amount you have cleared. On a flat-rate loan the saving is often much smaller, because the interest was calculated up front on the original amount. Most lenders also charge an early-settlement fee, which the calculator does not model.
