Upgrade calculators

Four calculators built for HDB upgraders, using current MAS & IRAS rules — TDSR 55%, MSR 30%, a 4.00% loan stress-test rate, 75% LTV, and 2026 stamp-duty tiers.

How much can you borrow & buy?

Based on TDSR (55%), MSR where it applies (30%), and the 4% stress rate.

Guidance only. These calculators apply general MAS/IRAS/CPF rules current in 2026 and make simplifying assumptions. They are not an offer of credit, a valuation, or tax advice. Your actual loan, stamp duty and CPF usage depend on bank assessment and your personal circumstances — confirm with your bank, IRAS and a conveyancing lawyer before you commit.
