HDB Upgrade Calculator

Thinking of upgrading from your current HDB flat?

The HDB Upgrade Calculator helps homeowners estimate whether the proceeds from selling their existing flat, together with their CPF savings and available financing, are sufficient for their next property purchase.

Whether you are upgrading to a larger HDB flat, an Executive Condominium (EC), a condominium or another private property, this calculator can help you estimate your affordability and plan your next move with greater confidence.

Part 1: Sale Proceeds

CPF Refund

Selling Cost


Part 2: Next Purchase

HDB Housing Grants

Loan Estimate

Next Purchase Costs

How Does The Calculator Work?

① Estimate
Sale Proceeds

Deduct outstanding loan, CPF refund, commission, legal fees and selling costs to estimate the proceeds available from the sale.

② Estimate
Purchase Costs

Calculate purchase price, stamp duties, legal fees, grants and other costs associated with the next property purchase.

③ Determine
Buying Affordability

Combine sale proceeds, CPF funds, grants and loan financing to determine affordability and estimate any surplus or shortfall.

Important Things To Note

For property owners aged 55 and above, CPF refunds from the sale will first be used to top up the CPF Retirement Account (RA) if the Full Retirement Sum (FRS) has not been met. Only the remaining balance, if any, will be credited back to the CPF Ordinary Account (OA) and may be available for the next property purchase.

As a result, the CPF funds available for the next property purchase may be lower than the CPF refund amount shown in this calculator. Homeowners aged 55 and above should verify their CPF balances and retirement account requirements directly with CPF Board before making any property purchase decisions.

Many homeowners are surprised to learn that CPF monies used for the purchase of the property, together with accrued interest, generally need to be refunded to their CPF account upon completion of the sale. As a result, the amount of cash received from the sale may be lower than expected, even if the property has appreciated in value.

This applies to both HDB and private residential properties where CPF funds were utilised.

Your housing loan will be fully settled from the sale proceeds before any balance is distributed to the owners.

For properties with multiple owners, the ownership share entered will affect how the net proceeds are allocated between the sellers. Normally most cases are 50/50 share unless otherwise stated by lawyer during purchase of the property.

For HDB purchases, housing grants such as the First-Timer Grant, Enhanced CPF Housing Grant (EHG) and Proximity Housing Grant (PHG) are subject to prevailing HDB eligibility conditions.

The grant amounts entered into this calculator are estimates only and do not guarantee grant approval. Buyers should verify their eligibility through their HFE Letter and the latest HDB guidelines.

Many buyers focus on the purchase price but overlook the impact of Buyer’s Stamp Duty (BSD) and Additional Buyer’s Stamp Duty (ABSD), where applicable. These costs are generally payable upfront and can substantially affect the total funds required for the next property purchase.

Buyers should ensure sufficient CPF and cash funds are available to meet these obligations.

The loan amount entered in this calculator is for estimation purposes only.

For HDB purchases, buyers should refer to their HFE Letter for the actual loan eligibility. For private properties, final loan approval depends on factors such as income, age, outstanding debts, credit assessment, TDSR requirements and bank lending criteria.

This calculator is intended as a planning tool to help homeowners estimate their potential sale proceeds and affordability for their next property purchase.

While every effort has been made to provide a reasonable estimate, actual figures may differ due to factors such as:

  • Final selling price achieved
  • Outstanding loan redemption amount at completion
  • CPF refund obligations, including accrued interest
  • Legal fees and disbursements
  • Agent commission payable
  • Stamp duties, grants and financing eligibility
  • Completion adjustments and other transaction-related costs

For a more accurate assessment based on your property’s actual loan balance, CPF usage and intended purchase plans, consider obtaining a personalised calculation before making any major property decisions.

This calculator is intended to provide a preliminary estimate and should not be relied upon as financial, legal or tax advice.

Actual transaction figures may differ due to market conditions, CPF adjustments, stamp duties, grant eligibility, loan approval, legal costs and other factors specific to each transaction.
