Income needed for a $800,000 mortgage
A common rule of thumb is the 28% front-end ratio: keep housing costs at or below 28% of gross income. To keep just the $5,322/month principal and interest within that limit, you'd want roughly $228,104 a year. Once property tax, insurance, and any PMI are added, the real income you'd want is higher.

What this estimate leaves out
- Property tax & insurance: usually escrowed into your payment — often 1–2% of the home's value per year combined.
- PMI: required on most loans with less than 20% down, adding to the monthly cost until you build enough equity.
- HOA dues: common for condos and planned communities, and not part of the loan.
- Down payment: this is the loan amount — your home price is this plus your down payment.
How the payment is calculated
A fixed mortgage uses standard amortization: each month, interest is charged on the remaining balance and the rest of the payment reduces the principal. The formula is principal × monthly rate ÷ (1 − (1 + monthly rate)−months). For $800,000 at 7% over 30 years that's about $5,322 a month in principal and interest.
