Formula

Monthly payment (principal + interest):

M=Ptimesfracr(1+r)n(1+r)n−1M = P \\times \\frac{r(1+r)^n}{(1+r)^n - 1}

With property tax, insurance, and HOA:

texttotalmonthly=M+fractexttax12+fractextinsurance12+textHOA\\text{total monthly} = M + \\frac{\\text{tax}}{12} + \\frac{\\text{insurance}}{12} + \\text{HOA}

FAQ

What is PMI? Private Mortgage Insurance, required when down payment is less than 20%.

How do I remove PMI? Once equity reaches 20%, request removal. Automatic cancellation at 22% equity.

Can I afford this mortgage? Use the 28/36 rule: housing costs ≤ 28% of income, total debt ≤ 36%.

What about adjustable-rate mortgages? This calculator is for fixed-rate mortgages. ARM payments can change after the initial fixed period.

How does the loan term affect total cost? Shorter terms have higher monthly payments but much less total interest.
