Concept
Effective Rate Converter
Flat rate, effective rate, and monthly installment are three ways of describing the same repayment. Convert them before you compare offers.
In plain English
A flat-rate quote often looks cheaper because the rate is applied to the original loan amount for the whole tenure. An effective-rate quote is calculated on the reducing balance, so the headline percentage is usually higher even when the monthly installment is the same.
This converter uses loan amount and tenure as the fixed base, then translates whichever number you have — flat rate, effective rate, or installment amount — into the other two. That gives you a cleaner like-for-like comparison before you speak to a banker.
The installment input is useful when a term sheet or hire-purchase quote gives you only the monthly payment. From that payment, you can infer both the flat rate and the effective-rate equivalent.
Try it with your numbers
Convert the quote into the rate you can actually compare.
Enter loan amount and tenure, then choose whether you have the flat rate, effective rate, or monthly installment. The calculator translates the rest.
The conversion assumes fixed monthly repayment for the full tenure. Fees, insurance, and early settlement rebates are not included.
Monthly installment
RM 10,000.00
Same payment used to translate between both rate types.
Effective rate
7.42% p.a.
Reducing-balance rate used for like-for-like bank comparison.
Flat rate equivalent
4.00% p.a.
Headline-style flat rate that gives the same monthly payment.
Monthly installment
RM 10,000.00
Total interest over tenure
RM 100,000.00
Total paid over tenure
RM 600,000.00
Effective rate is 3.42 percentage points higher than the flat rate for this structure.
We’ll check whether the quote is comparable with market terms.
Worked example
RM 500,000 over 5 years — 4.00% flat is not 4.00% effective.
- Loan amount
- RM 500,000
- Tenure
- 60 months
- Flat rate quoted
- 4.00% p.a.
- Monthly installment
- RM 10,000.00
- Effective rate equivalent
- 7.42% p.a.
- Flat rate equivalent of 7.42% effective
- 4.00% p.a.
Once the monthly installment is fixed, the flat and effective rates are just two labels for the same repayment stream. The mistake is comparing a 4% flat quote against a 6.5% effective quote without converting first.
What bankers watch for
- • Use the same loan amount and tenure before converting rates.
- • If you only know the monthly installment, enter that directly and infer both rates.
- • Flat-rate loans can still have early settlement formulas that change the real cost if you refinance or settle early.
- • Processing fees, stamp duty, legal fees, insurance, and guarantee fees are separate from rate conversion.
- • For bank comparison, effective rate is usually the cleaner number because it reflects the reducing balance.
