How The Instalment Is Worked Out

Each month, interest is charged on what you still owe. The instalment stays the same, so early payments are mostly interest and later ones mostly principal. That is why an extra repayment early in the loan saves more interest than the same amount paid later.

A one-point rise in the rate matters more than most people expect. Try the same loan at 2.6% and 3.6% and compare the total interest.

Assumptions And Limits

Standard reducing-balance loan with equal monthly instalments and a rate that stays the same for the whole tenure. Real bank packages reprice, so treat the result as a snapshot at today's rate.
The HDB housing loan rate shown as a preset is 0.1 percentage point above the CPF Ordinary Account rate. Check the current rate with HDB before relying on it.
Excludes fees, fire and mortgage insurance, stamp duty and legal costs.
Whether you can borrow this amount depends on loan-to-value limits, MSR and TDSR, which this tool does not test. Use the affordability calculator for that.
