Mortgage & Real Estate Calculators

Buying a home is the largest financial commitment most people will ever make. Before you start touring properties or talking to lenders, it pays to understand exactly how much house you can comfortably afford and what your monthly payments will look like under different scenarios.

Our mortgage affordability calculator uses the industry-standard 28/36 rule to determine a safe home price based on your income, debts, down payment, and current interest rates. Lenders use this same guideline when evaluating your application, so you'll know where you stand before you apply.

Once you have a target price range, the loan payment calculator breaks down your monthly principal and interest for any loan amount and term. Toggle between 15-year and 30-year mortgages to see how a shorter term saves tens of thousands in interest, or explore how even a small rate difference compounds over the life of your loan. The built-in amortization schedule shows exactly how your balance decreases over time.

If you're a contractor or real estate investor evaluating renovation projects, check out our contractor markup and margin calculator to price jobs accurately and protect your profit margins. And if you want to evaluate a property as an investment, the ROI calculator measures your annualized return so you can compare real estate against other opportunities. All CalcGrove calculators are free, private, and require no account.
