HDB Upgrade Calculator

If you sell your HDB, what can you upgrade to?

Three short steps. You'll see what your sale leaves you with, how much you could borrow, and two budgets: the most the rules allow, and a more careful planning figure.

Step 1 of 3

Your current HDB

Has your flat met its minimum occupation period?

Recent sales of similar flats nearby are the best guide.

HDB or bank loan still owed. Enter 0 if fully paid.

CPF you'll refund when you sell

The most accurate option. Log in to CPF and open your home ownership dashboard: the "What happens if" section shows the amount (CPF used plus accrued interest), for all owners combined.

Step 2 of 3

Who's buying

Number of buyers

Buyer 1

Gross monthly income before CPF.

Buyer 2

Enter 0 if not working.

Car, personal, renovation or study loans, and credit card repayments, for all buyers combined. Don't include your current HDB loan.

After selling, will any buyer still own another home?
Step 3 of 3

Your savings

All buyers combined, not counting the refund from your sale.

Only what you're prepared to use for the purchase.

Assumptions you can change

These are estimates, not government rules. Government rules are listed further down the page.

How this is worked out

Your sale. From the selling price we take off your outstanding loan, then the CPF refund (it goes back to your CPF, not to you as cash), then selling costs. What's left is your cash proceeds. If the sale can't fully cover the CPF refund, you don't have to top it up in cash, as long as you sell at market value.

Your loan. Banks must check that all your monthly debts stay within 55% of your income, tested at an interest rate of at least 4%, even when actual rates are lower. Commission and bonuses count at 70%. For two buyers, loan length is based on your income-weighted average age: up to 30 years with a 75% loan if it ends by 65, or a longer loan at 55%.

Your budget. We find the highest price where the loan, the minimum cash downpayment (5% or 10%, which can't come from CPF), the rest of the downpayment, stamp duty and fees can all be covered by your cash and CPF.

Ken's Planning Budget adds three careful assumptions of mine: a 4% rate, total repayments within 35% of income, and 6 months of repayments kept in cash, plus anything you set aside for renovation. It's a planning scenario, not a rule.

Rules and assumptions used

Government rules come from official sources and are dated. Assumptions are my estimates; you can change them above.

This version assumes you sell first, buy one private home with a bank loan, and that the property's lease is long enough for full CPF use (for example a new 99-year or freehold home).

Estimates only, for general information. Not a bank approval, loan offer or financial advice. Banks may assess your loan more conservatively, and policies, rates and prices change. Check with your bank, CPF Board, HDB and IRAS before committing.
