Property, loan and CPF details
Repayment estimate (optional)
The repayment is cash only — CPF cannot service an equity term loan.
How the limit is found
Maximum equity loan = borrowing limit (75%, or 45% with other housing loans) × valuation − outstanding loan − CPF used − CPF accrued interest. The CPF deduction exists because you'll have to refund that CPF money, plus the interest it would have earned, to your CPF account when you eventually sell the property — so the bank sets it aside from what you can borrow now.
The loan skips TDSR (Total Debt Servicing Ratio, the 55% income test on your borrowing) if it stays within 50% of your home's valuation instead of 75%: subtract the same outstanding loan and CPF figures, and whatever's left is the largest loan you can take without an income check. Borrow more than that amount, and the whole loan — not just the amount above it — must pass TDSR's 55% limit, at the 4% stress rate.
