Flat Rate vs EIR: How Much You Really Save Settling a Car Loan Early (2026)
One of the biggest changes under the Hire-Purchase (Amendment) Act 2026 is what happens when you pay off a car loan early. Under the old flat rate and the Rule of 78, settling early barely saved you anything. Under the new reducing-balance method, it can put real money back in your pocket. Here is why.
Why early settlement barely helped under the flat rate
With the old flat rate, the bank calculated the full interest for the entire tenure up front, on the original loan amount. The Rule of 78 then front-loaded that interest, so in the early years of the loan most of your instalment was paying interest, not principal. If you settled early, you had already "used up" a disproportionate share of the interest — so the rebate on your remaining balance was small.
Why the reducing-balance method rewards it
Under the new reducing-balance method with EIR, interest is charged only on what you still owe. Every ringgit of principal you repay immediately stops accruing interest. So when you settle early, all the future interest on the money you have already repaid simply disappears — a genuine saving.
A worked ringgit example
Take a RM72,000 loan over 9 years, and imagine settling it at the end of year 5:
| Flat rate 3% (+ Rule of 78) | Reducing balance ~5.4% EIR | |
|---|---|---|
| Total interest over full term | ~RM19,440 | ~RM19,400 |
| Interest effectively charged by year 5 | Front-loaded — most already incurred | Only on the balance owed each month |
| Saving from settling at year 5 | Small — modest rebate | Larger — unpaid interest is cancelled |
The headline monthly instalment is almost identical between the two methods. The difference shows up entirely in flexibility: if you come into a bonus, sell the car, or refinance, the reducing-balance loan lets you walk away having paid interest only for the time you actually borrowed the money.
Should you settle early?
- On a reducing-balance loan: yes, if you have spare cash and no higher-interest debt — you save the remaining interest with no penalty.
- On an old flat-rate loan: check the rebate first. Ask the bank for the exact settlement figure and whether a goodwill discount applies before deciding.
- Either way: clear higher-interest debt (credit cards, personal loans) before overpaying a cheaper car loan.
Frequently asked questions
Is there a penalty for settling a car loan early in 2026?
Under the new reducing-balance method there is no interest penalty — you simply pay the outstanding balance. On old flat-rate loans, the rebate is governed by the settlement terms; ask your bank for the exact figure.
What is the Rule of 78?
It was a method that front-loaded interest to the early years of a loan, so borrowers who settled early got a smaller rebate than the straight-line share suggested. The Hire-Purchase (Amendment) Act 2026 abolished it.
How do I compare a flat rate to an EIR?
As a rough guide, a flat rate's true EIR is about 1.8 times the flat rate — so a 3% flat rate is roughly 5.4% EIR. Our car loan calculator shows the true EIR of any flat-rate quote.
