Question: how to calculate how much house to buy?
Answer: To calculate your front-end ratio, divide your annual pre-tax income by 12, and then multiply this amount by 0.28. As an example, if your salary is $60,000 per year, dividing by 12 gives a gross monthly income of $5,000, and multiplying this by 0.28 gives a maximum mortgage payment of $1,400 per month.
