How it works
rent vs buy calculator takes your inputs and produces total rent paid, total cost to buy (net), buy monthly payment, equity after your stay. Cost out both sides — rent that grows each year versus a mortgage with equity building — across the years you plan to stay. You provide 10 inputs: Monthly rent (currency, in dollars) (default: 2200 dollars); Home price (currency, in dollars) (default: 450000 dollars); Down payment (currency, in dollars) (default: 90000 dollars); Mortgage rate (percent, in percent) (default: 6.5 percent); Loan term (years, in years) (default: 30 years); Years you plan to stay (years, in years) (default: 7 years); Annual property tax (currency, in dollars) (default: 7200 dollars); Annual home insurance (currency, in dollars) (default: 1500 dollars); Annual home appreciation (percent, in percent) (default: 3 percent); Annual rent increase (percent, in percent) (default: 3 percent). The calculator returns 4 outputs: Total rent paid (a secondary output); Total cost to buy (net) (the primary result); Buy monthly payment (a secondary output); Equity after your stay (a supplementary figure). Loans and mortgages are amortized instruments where the split between interest and principal shifts every month. Understanding the total cost of borrowing — not just the monthly payment — is the difference between a sustainable debt load and one that erodes your net worth over time. This calculator reveals the full amortization picture. The underlying formula: Buy net cost = down payment + payments - final equity | Rent total = rent x (1 + rent inflation)^years With the default values, total cost to buy (net) is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Formula
Buy net cost = down payment + payments - final equity | Rent total = rent x (1 + rent inflation)^years
Tips
- The 5-year rule of thumb exists because it roughly matches closing-cost recovery plus appreciation inflection.
- Run two scenarios: 3% appreciation and 0% — if buying only works at the rosy number, it is a bet, not a plan.
- Count maintenance (usually 1-2% of value annually) even if the calculator stays bare-bones.
- In expensive cities, the same down payment invested historically beats bought housing over 10+ years — check both.
