Method and assumptions
Amounts: at most 1,000,000,000 with two decimal places. Rates: four decimal places. Loan rates and percentages: 0–100; terms: whole years 1–100. Investment returns and inflation: −99–100; horizons: whole years 0–100. Invalid or excessive results are rejected.
Money is displayed to two decimals. Loan interest posts monthly in cents, with an adjusted final payment. Savings compound before each end-of-month deposit; no daily cash-flow dates are modeled.
Income 120,000, debts 0 and DTI 36% give a monthly housing budget of 3,600. With no down payment, PMI must be included and the returned total must stay within 3,600.
Calculations run in this page without sending financial inputs to a calculation service. Drafts are not saved by this calculator. Clipboard and CSV actions use the successful result; editing or reset invalidates it. Site advertising and account policies remain separate. No income verification or lender lookup is performed.
Insurance is a fixed 0.35% of price per year; PMI is 0.5% of loan per year above 80% LTV. These are planning assumptions. HOA, utilities, maintenance, closing costs and lender underwriting are excluded. Income zero yields no financed recommendation.
