Early settlement calculator: the Rule of 78 rebate, in numbers

Written by the Loankira editorial desk — Malaysian finance writers, every figure checked against BNM, LHDN, KWSP or PERKESO · Last reviewed: 3 October 2026

Early settlement is clearing a hire-purchase agreement before its last instalment, which under the Hire-Purchase Act 1967 earns a statutory rebate of unearned interest rather than a refund of the whole remaining schedule.

You decide to clear your car loan years ahead of schedule, expecting to save every ringgit of "remaining interest" on the repayment schedule. Then the bank's settlement letter arrives and the number is bigger than what you pictured. Nothing went wrong — you just ran into the rebate method baked into Malaysian hire-purchase contracts, and a law that is changing underneath it right now.

Why the settlement figure surprises almost everyone

A Malaysian car hire-purchase (HP) loan is normally quoted as a flat interest rate — say 3% a year on the amount financed, for the whole tenure. The bank multiplies that out for the entire term, adds it to the principal, and divides by the number of months. Every RM1,150 instalment therefore contains both principal and interest, and the total interest is "pre-computed" — fixed on day one, whether you keep the loan nine years or two.

When you settle early, you do not owe the remaining instalments in full. The law says the interest you have not yet "earned" the bank the right to must be rebated. But how much interest counts as unearned depends on the rebate method — and under the traditional Rule of 78, far less is rebated than people assume, because the interest is treated as front-loaded: most of it is considered earned in the first years of the loan. The practical consequence is blunt: the earlier you settle, the bigger the gap between "instalments remaining" and "actual settlement figure", but the more interest you still save overall. You need both numbers to make the decision, and this guide produces both.

What the law guarantees you

The Hire-Purchase Act 1967 (Act 27) governs car and motorcycle HP agreements in Malaysia. Its early-settlement provision (section 35) gives the hirer the right to return the vehicle or pay off the outstanding balance at any time and receive a rebate of the unearned finance charges. The rebate has historically been computed using the Rule of 78 — sometimes printed in the contract as "sum of digits" or "78s" — because that was the standard banking approximation for pre-computed interest.

That framework is now changing. The Hire-Purchase (Amendment) Act 2026 took effect on 1 June 2026 (Bank Negara Malaysia consumer guide, 17 March 2026) and moves new hire-purchase financing away from flat rates and the Rule of 78 toward the reducing-balance method priced on an effective interest rate (EIR). Providers have a transition window until 31 March 2027 (confirmed in the joint ABM–AIBIM–ADFIM statement of 16 March 2026), during which banks may still offer older Rule of 78 products, and banks are also offering goodwill discounts on early settlement of existing pre-computed HP agreements: from 1 June 2026, individuals and micro and small businesses with fixed-rate Rule of 78 agreements signed before 1 June 2026 or during the transition period can get one when they settle early, provided the account is not more than 90 days in arrears, under legal action or repossession, or under restructuring or a formal debt management programme. Each bank calculates its own discount, so ask for the figure when you request settlement. So depending on when you signed, your car loan is either a Rule of 78 contract you settle under the old math, or a new reducing-balance contract where the settlement is simply the outstanding principal plus accrued profit. The rest of this guide shows the Rule of 78 arithmetic, since that is what most existing car loans on the road today use. Rather than tamper with the statutory formula by hand, put the outstanding balance and remaining term into the early settlement calculator and read the rebate it produces.

The Rule of 78 rebate, in one formula

For an original term of n monthly payments, the sum 1+2+…+n is n×(n+1)÷2 — for a 12-month loan that sum is 78, which names the whole method. The lender "earns" interest in the same descending ratio: the full number of parts in month one, one part less each month after. When you settle with u payments still remaining, the rebate — the finance charge never earned — is:

Rebate = T × u × (u+1) ÷ [n × (n+1)]

where T is the total pre-computed interest over the full term. The settlement figure is then: (u × monthly instalment) − rebate. Simple to state; the numbers it produces are what surprise people, so let's run a real one.

Worked example: a RM60,000 car loan, step by step

Suppose you finance RM60,000 at a 3% flat rate over 60 months (5 years). Step by step, with every figure checked:

1. Total interest. T = 60,000 × 3% × 5 years = RM9,000.
2. Monthly instalment. (60,000 + 9,000) ÷ 60 = RM1,150.
3. You settle after 24 payments, so u = 36 payments remain.
4. Pre-computed balance. 36 × 1,150 = RM41,400.
5. Rebate. 9,000 × 36 × 37 ÷ (60 × 61) = 9,000 × 1,332 ÷ 3,660 = RM3,275.41.
6. Settlement figure. 41,400 − 3,275.41 = RM38,124.59.

Read that carefully: you have paid 24 instalments (RM27,600) and still owe RM38,124.59, even though "half the months are gone". Under the Rule of 78, of the RM9,000 interest, RM5,724.59 is treated as already earned in the first two years. Your payoff saving versus holding to month 60 is the RM3,275.41 rebate — real money, but less than the RM4,500 "half of remaining interest" intuition suggests. The same formula at other points on this loan:

The table shows the two forces pulling against each other: settling sooner saves more total interest (the rebate is bigger), but the cheque you must write is also bigger. For comparison, a true reducing-balance calculation at the equivalent effective rate leaves about RM38,000 outstanding at month 24 — only about RM120 below the Rule of 78 figure on this short 5-year loan. The Rule of 78 penalty is modest at 3% flat over 5 years and grows on longer, higher-rate tenures; on a 9-year loan the same method can add several hundred ringgit to the settlement.

When early settlement makes sense — and when it doesn't

Three honest tests before you pay. First, the money test: RM38,124.59 sitting in a fixed deposit or ASB at 3.5–4% is producing income; compare that return against the implicit cost of the HP interest you are cutting off, not the headline rate. A low flat-rate car loan (2.5–3% flat) is one of the cheapest debts a Malaysian household carries; check your bank's current published hire-purchase rates before comparing, because they change often. Second, the cash-flow test: clearing the instalment frees RM1,150 a month, which matters if you are pushing your Debt Service Ratio close to a bank's limit before a home loan application — a settled car loan drops straight out of your DSR numerator (see the DSR guide linked below). Third, the paperwork test: get the official settlement letter from your bank first, check its validity window (it is usually short and varies by bank, so note the expiry date printed on the letter), and confirm whether any settlement admin fee applies before comparing figures yourself.

Common mistakes

Assuming the settlement equals "instalments left × instalment amount" — it doesn't; the rebate comes off that number and, separately, some banks add a settlement fee on top. Assuming the rebate is a straight pro-rata of remaining interest: under the Rule of 78 the early years rebate much less than pro-rata. Settling an old flat-rate HP only to re-borrow at a personal loan rate of 8%+ to fund it — that trades cheap debt for expensive debt. Forgetting the ownership transfer: under hire-purchase the bank holds the title, so after full settlement you must collect the vehicle title/ownership documents and, where required, complete the ownership transfer; a settlement receipt is not the transfer. And for new contracts, not asking whether the agreement is flat-rate Rule of 78 or EIR reducing-balance — during the transition period both exist at the same bank, and the settlement math is completely different.

Frequently asked questions

Can my bank refuse to let me settle early?

No. Section 35 of the Hire-Purchase Act 1967 gives the hirer a statutory right to settle the outstanding balance at any time with a rebate of unearned charges. Banks can require the official settlement figure and a validity window, but they cannot contract out of the right itself.

Does early settlement improve my credit score?

There is no credit "score" that rises because you settled early. What changes is your CCRIS record showing the facility closed and your monthly commitments falling — which lowers your DSR and helps a future loan application. A history of on-time payments is what matters on the report itself.

Why is my settlement figure higher than the outstanding principal on my statement?

Because a pre-computed statement shows the full remaining instalments (principal plus reserved interest), and the Rule of 78 rebates only part of the reserved interest — more so the longer you have been paying. Ask the bank to break the settlement letter into pre-computed balance, rebate, and fees so you can check each line against a calculation like the one above.

My loan is under the new EIR method — is early settlement better now?

Under the reducing-balance method introduced by the Hire-Purchase (Amendment) Act 2026, the settlement is the actual outstanding principal plus profit accrued to date — no front-loaded rebate games. Whether it is cheaper overall depends on the EIR quoted versus the old flat rate; compare the total cost over the months you actually expect to keep the loan, not the sticker rate.

Run your own numbers

The car loan calculator builds the full pre-computed schedule — total interest and monthly instalment — which is the input every Rule of 78 rebate is computed from. If a settled car loan is part of a home loan plan, check the room it frees with the home loan DSR calculator, and read the Rule of 78 explained for the mechanics behind the formula above.
