Home Loan Calculator
Estimate your monthly home loan repayment, total interest, and full repayment breakdown.
What this estimate includes
The loan uses a reducing-balance calculation and shows principal, interest and the remaining balance over time. Upfront cash is listed separately, including the down payment, Buyer's Stamp Duty and an estimate for legal work.
Check before deciding
ABSD, HDB rules, CPF usage, loan-to-value restrictions and lender fees can change the cash required. Confirm your eligibility and duties with the bank, CPF Board, IRAS and conveyancing lawyer.
Frequently asked questions
How is my monthly home loan repayment calculated?
It uses the standard amortising formula based on your loan amount, annual interest rate and tenure, spreading principal and interest evenly across every month of the term.
What is the difference between principal and interest?
Principal is the amount you borrowed; interest is the lender's charge for borrowing it. Early payments are mostly interest, and the balance shifts toward principal over time.
How is stamp duty calculated?
In Singapore, Buyer's Stamp Duty (BSD) on residential property is tiered from 1% up to 6% on higher value bands. Additional Buyer's Stamp Duty (ABSD) may also apply depending on residency and how many properties you own.
What is the margin of finance / down payment?
In Singapore the Loan-to-Value limit for a first private home loan from a bank is typically up to 75%, so you usually need at least 25% down, with part payable in cash. HDB loans differ.
Does a lower interest rate make a big difference?
Yes. Over a 25 to 35 year tenure, even a 0.5% difference in rate can change your total interest by a substantial amount. Try nudging the rate to see the impact on both your monthly payment and total interest.
Should I choose a longer or shorter tenure?
A longer tenure lowers your monthly payment but increases total interest paid. A shorter tenure costs more each month but saves significantly overall. Find a balance that fits your budget.
