Buying with

An EC can only be financed with a bank loan.

Interest Rate Floor

HDB assesses its loans at a 3% floor; banks must use MAS's 4% medium-term floor. Set by the loan type above.

Assumed LTV

HDB concessionary loans and bank loans both go up to 75% LTV.

MSR applies only to HDB flats and Executive Condominiums purchased directly from a developer. If you are buying a resale EC whose minimum occupation period (MOP) has passed, or any private property, only TDSR applies. The EC MOP is 5 years, rising to 10 years for ECs on sites whose land tender closed on or after 8 May 2026 (MND, 8 May 2026). Those ECs can be sold to any buyer only after 15 years instead of 10.

Frequently Asked Questions

What is MSR?

Mortgage Servicing Ratio — a regulatory cap requiring that monthly repayment on an HDB flat or Executive Condominium (purchased from developer) cannot exceed 30% of the borrowers' combined gross monthly income.

Why is the average age income-weighted?

HDB uses the income-weighted average age of all borrowers to determine the maximum loan tenure, then rounds the result up to the next whole year. A higher-earning older borrower will push the average age up more than a lower-earning younger one.

Why a 3% interest rate floor for HDB?

Even though the actual HDB concessionary loan rate (CPF OA rate + 0.1% = currently 2.6%) is lower, HDB assesses your eligibility against a 3% floor as a buffer. Bank loans use a 4% medium-term floor under MAS rules.

Why does the tenure cap matter?

Tenure = min(cap, 65 − average age), where the cap is 25 years for an HDB flat and 30 for an EC. Older buyers therefore get shorter tenures, which raises the monthly repayment and reduces the maximum loan supportable under MSR. A bank can lend for longer, but the LTV limit then falls from 75% to 55%.

What if only one owner is buying?

Choose 1 Owner. The calculator will use Owner 1's age as the average age and only their salary as the basis for MSR.
