Rule of 78 Early Settlement: The Penalty You're Probably Paying

If you signed a car loan in Malaysia before 1 June 2026, the formula that decides what you get back when you settle early has a name and a number: Rule of 78. It's been the standard for hire-purchase early-settlement rebates since the Hire-Purchase Act 1967 came into force. From June 2026 it's been abolished for new loans² under HP Act 2026 — but if your existing loan is still on it, this guide walks through what you'd actually get back, and what the new bank-led "goodwill discount" is designed to fix.

What Rule of 78 actually is

When you take a hire-purchase loan in Malaysia at a flat interest rate, the bank pre-calculates the total interest you'll pay across the full loan tenure and divides it evenly into your monthly instalment. Whether you have RM50,000 outstanding or RM1,000 outstanding, your monthly payment stays the same.

If you settle the loan early — say in year 3 of a 7-year loan — the bank owes you back a portion of the unearned interest. Rule of 78 is the formula that decides how much.

The name comes from the sum 1 + 2 + 3 + ... + 12 = 78. For a 12-month loan, you'd allocate the interest in 12/78 in month 1, 11/78 in month 2, and so on down to 1/78 in month 12. For longer loans, the same logic extends — a 24-month loan uses a denominator of 24 × 25 / 2 = 300; an 84-month loan uses 84 × 85 / 2 = 3,570.

The formula

The rebate (money you get back) on early settlement under Rule of 78 is:

rebate = total interest × m(m+1) / n(n+1)

where:

• m = number of months remaining when you settle
• n = total months in the original loan tenure
• total interest = the full pre-calculated flat-rate interest

What makes it unfair

The numerator m(m+1) shrinks much faster than a straight-line proportional rebate would. If you have half the loan tenure remaining, you get back roughly a quarter of the interest, not half. Bank Negara's own consumer guide puts the criticism plainly:

"The Rule of 78 method frontloads interest payments, resulting in higher initial interest costs and a larger outstanding principal amount due in the event of early settlements."⁵

BNM has also noted Malaysia is now aligning with global best practice — many countries banned Rule of 78 for consumer credit years ago³.

Worked example — RM 60,000 car loan, settle at year 3

Take an RM 60,000 car loan, 7-year tenure (84 months), 3.5% flat rate:

• Total interest (flat): 60,000 × 3.5% × 7 = RM 14,700
• Monthly instalment: (60,000 + 14,700) / 84 = RM 889.29
• After 3 years (36 months paid), 48 months remaining

Rule of 78 rebate:

rebate = 14,700 × (48 × 49) / (84 × 85)
       = 14,700 × 2,352 / 7,140
       = RM 4,842

Straight-line proportional rebate (what feels fair):

rebate = 14,700 × 48 / 84
       = RM 8,400

Difference: you "lose" RM 3,558 to the Rule of 78 formula — money that would have been refunded under a simple proportional calculation but stays with the bank because the formula front-loaded the interest collection.

The 1 June 2026 cutoff — who's still on Rule of 78

The Hire-Purchase (Amendment) Act 2026 abolishes Rule of 78 for new loans signed from 1 June 2026². Three groups remain on it:

1. Anyone whose HP agreement was signed before 1 June 2026. Loan terms don't change retroactively — your original contract continues until paid off or settled.
2. Anyone signing during the transition window 1 June 2026 to 31 March 2027 with a bank that hasn't yet completed system upgrades to offer reducing-balance HP. The Ministry of Domestic Trade and Cost of Living explicitly allowed banks to keep issuing Rule-of-78 loans during this period⁴.
3. Anyone who actively chooses Rule of 78 even when reducing balance is offered (unlikely, but legally permitted).

If you're in groups 1 or 2 and considering early settlement, the goodwill discount below is the key new option. Note that personal loans follow a separate, later timeline for the same Rule of 78 abolition — don't assume the car-loan cutoff applies to other credit.

The goodwill discount for existing loans

From 1 June 2026, the Association of Banks in Malaysia (ABM), Association of Islamic Banking and Financial Institutions Malaysia (AIBIM), and Association of Development Finance Institutions of Malaysia (ADFIM) jointly committed to offering a goodwill discount to customers settling existing Rule-of-78 loans early⁴. The discount makes the outstanding balance "more comparable to what it would have been under the reducing balance method."

Eligibility:

• HP agreement signed before 1 June 2026 OR during the transition window ending 31 March 2027
• You choose to early-settle (not just pay ahead)
• Account is not in arrears beyond 90 days, not under legal action, not under restructuring & rescheduling, not under formal debt management

The exact discount amount is decided per-bank, based on your loan's tenure and how far into it you are. Banks must disclose the discount when you request the early-settlement figure⁴.

Should you settle early?

The math now has three variables instead of two:

1. The Rule of 78 rebate — what you'd get back under the original formula
2. The goodwill discount — what the bank adds on top, from June 2026
3. The opportunity cost — what your lump-sum cash could otherwise earn (EPF, ASNB, savings)

Steps to decide:

1. Request the early-settlement figure from your bank. After 1 June 2026, the figure should already include the goodwill discount if you're eligible.
2. Compare the settlement figure to your outstanding principal × (interest rate × remaining years) — that's the rough total interest you'd avoid by settling vs continuing scheduled payments.
3. Compare against the return your settlement cash could earn elsewhere. EPF's FY2025 dividend was 6.15%; ASNB's was 4.25%. If your car loan effective rate is below either, parking the cash elsewhere may beat settling.
4. Check MRTA implications — many HP loans carry MRTA financed into the loan. Settling early may make the MRTA unrecoverable depending on the policy terms; confirm with your bank.

For everyday borrowers carrying RM30,000-80,000 of HP balance with a few years to go, the combination of Rule of 78 rebate + 2026 goodwill discount usually makes early settlement worthwhile — but only if you have the cash to spare without dipping into the emergency fund.
