How this repayment estimate works

For a constant rate, the monthly instalment is P × r ÷ (1 − (1 + r)⁻ⁿ), where P is the loan amount, r is the annual rate divided by 12 and n is the number of months. At 0% interest, divide P by n.

This is an independent planning estimate. The schedule rounds monthly interest and payments to cents and adjusts the last payment to clear the balance. It assumes payments at month-end and an unchanged rate. It excludes fees, insurance, missed payments, early repayment and future rate changes. Your lender's rounding and payment dates may differ. This mode does not assess MSR, TDSR, CPF usage or loan approval.

Worked examples, not loan offers

A hypothetical S$300,000 loan over 25 years at a constant 2.6% has a regular monthly repayment of about S$1,361. A S$120,000 loan over 10 years at 0% has a monthly repayment of S$1,000 and no interest.

HDB eligibility update — 24 August 2026: for new HFE applications, HDB loan income ceilings are $16,000 for families, $8,000 for eligible singles buying alone, and $24,000 for eligible extended families (each family nucleus within $16,000). The $18,000 ceiling is for qualifying new ECs. This calculator does not check income-ceiling eligibility or grant/loan approval; an estimate is not an HFE outcome. Read the new rules and existing-HFE guidance.

Resale cash-readiness breakdown

Already choosing a resale flat? Check the remaining cash needed using your confirmed financing. This does not calculate loan eligibility, grant entitlement, stamp duty or CPF usage limits.

Enter amounts in Singapore dollars. Calculations stay in your browser. Cash-over-valuation is cash-only. Usable CPF is a purchase allocation, not your full OA balance. Estimate stamp duty separately and include any unpaid cash-funded duty in the reserve below.

Agreed purchase price (S$)

Enter the full resale price, including any deposit already paid.

HDB valuation (S$)

Use the Request for Value amount. If it is not available, this breakdown cannot confirm cash readiness.

Confirmed loan amount to draw (S$)

Use your lender-confirmed amount for this purchase, not a theoretical maximum. Your HFE/lender determines eligibility.

Usable CPF for the flat price (S$)

After CPF retention, lease/usage limits and any CPF allocated to fees. Include confirmed grants only if not already counted in this amount.

Option/exercise deposit already paid (S$)

Part of the price, not an extra charge. Enter 0 if unpaid; combined resale deposit is capped at S$5,000.

Cash available now (S$)

Exclude the deposit already paid. Do not include CPF or sale proceeds not yet available.

Remaining costs and cash buffer (S$)

Cash reserved for unpaid BSD/ABSD, legal/admin/valuation fees, insurance, agreed agent fees and your buffer. Exclude costs already paid or separately funded by CPF; do not count the deposit again.

Fill in all seven amounts to see the cash you need from now, and any shortfall.

HDB loan calculator guide

Use the estimate to set a realistic viewing budget, then confirm your eligibility and loan amount through an HDB Flat Eligibility (HFE) application before committing to a flat.

Choose the right HDB calculator estimate

Already know your loan amount? Start with Monthly repayment to see the instalment, interest and balance schedule. Still choosing a flat budget? Select How much can I afford? and enter income, cash, CPF and existing debts. A repayment you can calculate is not automatically a loan you qualify for.

For a BTO or resale purchase, use the HDB downpayment guide to separate the purchase price, loan and upfront funds. Keep any separately agreed buyer-agent fee, renovation and other moving costs outside the housing-loan estimate.

How does this HDB loan calculator estimate affordability?

It applies the 30% Mortgage Servicing Ratio, an HDB loan eligibility rate, your selected tenure, the 75% loan-to-value limit and your available cash plus CPF. The result is a planning estimate, not a loan offer.

What HDB loan interest rate does the calculator use?

The current HDB concessionary interest rate is 2.6% per year for 1 October to 31 December 2026. It is pegged at 0.1 percentage point above the CPF Ordinary Account interest rate and reviewed quarterly.

How much can HDB lend for a flat purchase?

The published maximum loan-to-value limit is 75% of the purchase price for a new flat, or 75% of the lower of the resale price and HDB valuation for a resale flat. Your approved amount can be lower after HDB assesses your income, age, remaining lease and credit profile.

Is this calculator the same as an HFE letter?

No. This calculator is an independent planning tool. Your HDB Flat Eligibility letter confirms your housing grants, HDB loan eligibility and actual eligible loan amount.

Can I use this HDB calculator for a BTO or resale flat?

Yes, for an initial home-loan estimate. Enter the amount you intend to borrow, not the full BTO or resale price, in Monthly repayment. Use How much can I afford? for a separate income, cash and CPF budget estimate. This tool does not calculate BTO staged payments, resale cash-over-valuation or your grant entitlement. For a new-flat budget that includes grants, use the HDB BTO calculator instead.

Is this an HDB renovation loan calculator?

No. This page estimates home-purchase financing, not a renovation loan. Budget separately for renovation, furniture and moving costs. For renovation borrowing, use the lender's quoted rate, fees and repayment schedule rather than this tool's HDB rate preset or housing affordability result. To estimate a renovation instalment, use the renovation loan calculator on this site.

Who is eligible for an HDB housing loan?

At least one applicant must be a Singapore Citizen, with no more than one previous HDB housing loan, no disqualifying private-property interest, and average gross monthly household income within the ceiling: $16,000 for families, $24,000 for extended families or $8,000 for eligible singles, for HFE applications from 24 August 2026. HDB confirms eligibility through your HFE letter, not through this calculator. Full HDB loan eligibility guide

Is an HDB loan at 2.6% cheaper than a bank loan?

Not always. The HDB concessionary rate of 2.6% moves with the CPF Ordinary Account rate and is reviewed quarterly, while bank packages price off market rates and are assessed at a 4% stress rate under the 55% TDSR limit. Compare total interest over your tenure and the cash and CPF you must put down before choosing. Read the HDB loan vs bank loan comparison for the current trade-offs and switching rules.

Add grants, CPF and cash correctly

Check the Enhanced CPF Housing Grant and HDB resale grants before entering your available funds. Then review how CPF OA can be used and separate the mandatory cash items with the HDB downpayment guide.
