Advanced Loan Prepayment & Early Settlement Simulator
Model a Malaysian style reducing balance loan, test lump sum and monthly extra payments, and see how much interest you save and how many years you can cut from your housing or term loan.
This calculator is for estimation only and does not replace your bank official quotation. Actual figures can differ due to rate changes, bank compounding rules, lock in penalties and fees.
1. Loan details and prepayment setup
Shorten tenure is the common Malaysian style when you pay extra without formally restructuring the loan. Recast installment is more common when the bank officially recalculates the payment.
Scenario B - lump sum injection
Scenario C - extra monthly payment
Scenario D - advanced multiple events
Add custom prepayment events such as yearly bonuses or a short burst of extra payments.

Outstanding balance - normal vs prepayment
Tenure comparison
Interest vs principal over time - prepayment scenario
This simulator uses a standard reducing balance formula for term loans with a fixed effective annual rate. It first builds a normal schedule with no extra payments, then applies your prepayment events to see how much faster the loan can finish and how much interest you can save.
- Installment is calculated with the usual EMI formula based on loan amount, rate and tenure.
- Lump sum and extra payments are treated as direct reductions of principal after the normal installment.
- For the shorten tenure option, the installment stays the same and the loan ends earlier when the balance hits zero.
- For the recast option, whenever you prepay the simulator recalculates the installment based on the remaining balance and months.
- Charts show how the prepayment path diverges from the normal path over time.
What is a reducing balance loan in Malaysia
Most Malaysian housing loans, SME term loans and personal loans are reducing balance facilities. This means interest is charged on the outstanding principal after each payment, not on the original loan amount. As you pay down the principal, the interest portion of each installment becomes smaller and the principal portion becomes larger.
How does extra payment reduce your housing loan interest
Extra payments directly reduce the principal. Once the principal drops, every following month is calculated on a smaller balance, so the interest charged each month is lower. Over many years this snowball effect can translate into very large savings, especially for long tenures such as 25 to 35 year mortgages.
With the shorten tenure approach, you keep paying the same monthly installment but finish the loan earlier. With the recast approach, your monthly installment is reduced but the tenure remains similar to the original plan. This simulator lets you compare both.
Shorten tenure vs reduce installment - which is better
There is no single best answer. Shortening the tenure usually saves more interest across the whole life of the loan because you stay at the higher installment and clear the debt faster. Reducing the installment creates more monthly cash flow but lowers the interest saving compared with tenure shortening. Many Malaysian borrowers prefer a hybrid approach - use extra payments aggressively when income is strong, but switch to a lower installment if cash flow becomes tight later.
How to use this Loan Prepayment & Early Settlement Simulator
- Enter your loan amount, effective rate and original tenure at the top.
- Select whether you want to keep the installment and shorten the tenure or reduce the installment instead.
- Use the lump sum section to model a one off injection such as EPF withdrawal, bonus or sale of an asset.
- Use the extra monthly section to see the effect of topping up every month such as RM200 or RM500 on top of your normal amount.
- Use the advanced events section to add multiple events such as yearly bonuses or a short burst of intense prepayment.
- Click calculate and review the interest saved, years shaved off, tables and charts.
Example - RM500k loan, prepay RM20k at year 5
A common scenario is a RM500,000 housing loan at around 4 to 4.5 percent effective rate across 30 years. A one off RM20,000 prepayment at the 5 year mark combined with a small monthly top up can easily shave several years off the tenure and save tens of thousands in interest. Use the simulator to plug in your own figures and discuss ideas with your banker or financial planner.
Limitations and what this calculator does not cover
Real world loans can be more complicated than a clean reducing balance schedule. This tool does not model:
- Future changes in BR or SBR that cause the effective rate to move up or down.
- Lock in penalties, early settlement fees or partial payment charges that some banks still impose.
- Legal fees, valuation fees, stamp duty, MRTA or MLTA premiums.
- Offset features on flexi loans where current account balances reduce the effective principal.
Treat the results as a planning guide and a way to understand how extra payments affect your loan. Always check your bank official figures before signing any variation or settlement letter.
