How it works
city-specific rent vs buy calculator takes your inputs and produces monthly cost to buy, monthly cost to rent, monthly savings (better). Rent vs buy comparison adjusted for local market conditions and property tax rates. You provide 4 inputs: Local Median Home Price (currency, in dollars) (default: 400000 dollars); Median Monthly Rent (currency, in dollars) (default: 2200 dollars); Property Tax Rate % (percent, in percent) (default: 1.2 percent); Down Payment (currency, in dollars) (default: 80000 dollars). The calculator returns 3 outputs: Monthly Cost to Buy (the primary result); Monthly Cost to Rent (a secondary output); Monthly Savings (Better) (a secondary output). 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. With the default values, monthly cost to buy 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.Tips
- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Compare the total cost of borrowing, not just the monthly payment. A lower monthly payment often means paying thousands more in interest over the life of the loan.
Frequently asked questions
How does location affect rent vs buy?
High-tax areas: rent wins. Low-tax: buy wins. HCOL: rent can be cheaper short-term. LCOL: buy is almost always better.
How accurate are the calculator results?
The math is exact — the same formulas a financial professional would use by hand. The precision of the output depends entirely on how realistic your inputs are. Use your actual numbers rather than estimates when possible. The defaults are reasonable starting points, but your real income, rates, and timeline will produce a different result.
What should I enter for local median home price?
Enter your actual local median home price value. The default of 400000 dollars is a common starting point, but replace it with your real figure for an accurate result.
