What the Affordability calculator does Home Affordability Calculator is built for money decisions — loans, savings, payments, and taxes. Estimate a home price from income, debts, rate, and a payment ratio. You enter gross annual income, max housing ratio, other monthly debts, interest rate, term, and down payment, then Simple Calculators computes the result instantly. Rates, fees, and tax rules vary by lender and country, so treat results as planning numbers, not a contract. How the math works Max housing payment = income × ratio / 12, minus estimated monthly tax/insurance. Loan principal is implied by that payment, then a down-payment percent is added back to estimate price. The formula: Loan = M × ((1 + r)^n − 1) ÷ (r × (1 + r)^n); price = loan ÷ (1 − down %). M is the monthly principal & interest budget, r is the monthly rate, and n is the number of months.
