I'd created a calculated for your convenience;
with this compact calculator you would only need 3 inputs, and you'll be able to find out your property details and monthly payment within seconds! Comes with detailed calculation of required Cash & CPF for designated property price, also calculates monthly payment (EMI), while taking CPF OA contribution into consideration.
Also comes with adjustable tenure and interest rates.
Feel free to request for a more comprehensive calculation if you like (:
