Early settlement
Loan Early Settlement Calculator (Rule of 78)
Settling an existing Malaysian flat-rate car or personal loan early? Estimate what you'd pay today, how much a Rule of 78 rebate gives back, and what the headline flat rate really costs as an effective annual rate.
How it's calculated
Total interest (flat rate) — I = principal × annual flat rate × tenure in years. Flat-rate loans charge interest on the original principal for every month, so the total is fixed at signing.
Equal monthly instalment — M = (principal + total interest) ÷ tenure. The same amount every month, with the interest portion front-loaded.
Rule of 78 rebate — interest is allocated in a "sum-of-digits" pattern: month 1 absorbs the largest slice, month n the smallest. The rebate at settlement is the sum of the digits for the unpaid months ÷ the sum of all digits. Formula: rebate = total interest × (n−k)(n−k+1) ÷ (n × (n+1)).
Settlement = remaining instalments (n−k) × M, minus the interest rebate, plus any early-settlement penalty.
Effective rate (APR) — solved numerically from M = P × i (1+i)^n ÷ ((1+i)^n − 1), then annualised. For Malaysian flat-rate loans this is typically ~1.7–1.9× the headline rate.
Common questions
Why is the rebate not just half the remaining interest?+
Because of the Rule of 78 (sum-of-digits) allocation. Interest is front-loaded — month 1 of a 60-month loan absorbs 60/1,830 of the total interest, while month 60 absorbs only 1/1,830. Settle at month 12 and roughly 64% of the total interest is still unpaid and rebated. Settle at month 48 and only ~4% is left to rebate.
Do Malaysian loans still use the Rule of 78?+
Some existing flat-rate loans can still be quoted with a Rule of 78 / sum-of-digits rebate, but this is not universal. The Hire Purchase (Amendment) Act 2026 (in force 1 June 2026, administered by KPDN) moves new hire-purchase financing toward reducing-balance interest, and Islamic or flexible-rate products may use different rebate methods. Use this tool only when your agreement or bank quote matches a Rule of 78 style calculation.
Is there a penalty for early settlement?+
It depends on your loan agreement and product type. Some facilities impose a penalty, minimum holding period, administrative deduction, or different rebate treatment; others do not. Check the early-settlement clause and enter the penalty or deduction in RM to see the net saving.
What is the "effective rate" the calculator shows?+
A flat 7% per year on a 5-year loan sounds cheap, but a reducing-balance loan paying the same monthly amount would actually be priced at around 12.5% per year. The effective rate (APR) is the apples-to-apples comparison number. Always compare loans on effective rate, not the headline flat rate.
Why does the calculator say my final figure is approximate?+
Because the final quotation can depend on the exact settlement date, bank-specific rebate treatment, administrative deductions, penalties, and whether your product still uses Rule of 78 at all. Always request the bank's written settlement quotation before paying.
Should I settle early?+
If the saved interest minus the penalty is meaningfully positive — and the cash would not earn more elsewhere — settling early is usually worth it. The earlier in the tenure, the better, because the Rule of 78 front-loads interest. Past the loan's halfway point the rebate shrinks fast and settling stops being attractive.
