Coastal Cabana EC Affordability Calculator

This EC affordability calculator for Coastal Cabana works out the largest housing loan a household income can carry under both MAS ceilings at once, the 30% mortgage servicing ratio and the 55% total debt servicing ratio, reports which one binds, and checks the household against HDB’s income ceiling for new executive condominiums and the CPF Housing Grant tiers. The rules behind it are explained on the housing loan information page.

How an EC Loan Is Sized at Coastal Cabana

The bank begins with assessed income: fixed salary in full, plus bonuses and commissions at 70% after the haircut, averaged over twelve months. The mortgage servicing ratio allows up to 30% of that income for the housing loan; the total debt servicing ratio allows up to 55% for all debts together, existing repayments included. The calculator turns the lower of the two into a loan at the assessment rate, the higher of the 4% MAS floor or the rate you enter, over a tenure that ends by age 65 on the income-weighted average age and stays within 30 years, so the 75% loan-to-value limit holds.

The binding cap is the feature to read first: for most households it is the MSR, which means other debts do not change the answer unless they exceed a quarter of income. The income ceiling row flags a household above the ceiling for new ECs, and the grant row applies the CPF Housing Grant tiers, which stop well before the ceiling. The progressive payment calculator and the stamp duty calculator complete the picture.
