A home loan calculator helps estimate monthly repayments, total interest payable and the income required to qualify for a home loan in Singapore. This tool covers all property types from HDB flats, condos, landed properties and executive condominiums with adjustable inputs for loan amount, interest rate and tenure. It also calculates the minimum income needed to meet TDSR (55%) and MSR (30% for HDB/EC) requirements.

Whether your planning a first property purchase or assessing affordability for an upgrade this calculator provides the numbers needed to make an informed decision.

More Details

Monthly repayments are calculated using the standard amortisation formula which factors in loan principal, interest rate and tenure. Each payment consists of interest and principal portions. Early payments are mostly interest while later payments are mostly principal.

Total Debt Servicing Ratio (TDSR) limits all monthly debt payments to 55% of gross income. Banks use a 4% stress test rate when calculating TDSR. This affects maximum borrowing capacity significantly.

Loan-to-Value (LTV) determines the maximum loan as a percentage of property value. First property: 75% (bank) or 80% (HDB loan). Second property: 45%. If age + tenure exceeds 65: reduced to 55%.

Fixed rates (1.50%-1.80%) stay constant for 2-5 years offering payment certainty.  Floating rates (SORA+0.25% to 0.50%) move with market conditions and are currently lower but can increase.

Bank Rates Are Now Lower But Is Switching Right for Everyone?

With rates at multi-year lows and SORA around 1.1% to 1.2%, 2026 is an excellent time to refinance. Here's practical advice for different situations:

When assessing affordability banks don't use the actual loan rate but tapply a stress test rate of at least 4%.

This means a loan advertised at 1.75% is assessed as if the rate were 4% which is significantly reducing maximum borrowing capacity. Additionally only 70% of variable income (bonuses, commission) is counted towards your income. This calculator uses actual rates for repayment estimates but the "minimum income required" figures don’t factor in the 4% stress test. Quote Icon

Understanding Loan Affordability

How Much Can You Really Afford?
The 4% Stress Test: Banks calculate affordability using at least 4% interest rate, regardless of actual rate. This protects borrowers from future rate increases but limits borrowing capacity.
Income Assessment:
  • Fixed income: 100% counted
  • Rental income: 70% counted
  • Variable income (bonus, commission, OT): 70% counted
  • Eligible financial assets: 30% converted over 48 months
Quick Affordability Reference:
Monthly Income Max Loan (TDSR 55%, 4% stress, 25 yrs)
$8,000 $835,000
$10,000 $1,045,000
$12,000 $1,255,000
$15,000 $1,565,000

How to Use Our Mortgage Calculator (FAQs)

What loan amount should I enter?

Enter the amount being borrowed typically 75% of property price for bank loans. Subtract the down payment from the purchase price to get the loan amount.
Use the rate from the loan package being considered. Fixed rates currently range from 1.50% to 2.00%. Floating rates are approximately SORA + bank spread around 1.40% to 1.60% in 2026.
Longer tenure (25 to 30 years) reduces monthly payments but increases total interest. Shorter tenure (15 to 20 years) means higher payments but significant interest savings.
Total interest is the cumulative interest paid over the entire loan tenure. This is in addition to repaying the original loan amount aka principal.
The calculation works for HDB, condo, landed, and EC. Simply enter the appropriate loan amount, rate and tenure for the specific property.
The calculator provides close estimates based on standard formulas. Actual repayments may differ slightly due to rounding, payment dates and bank-specific calculation methods.
