PMI (Private Mortgage Insurance) is typically required when your down payment is less than 20% of the home price. It protects the lender, not the borrower, and is removed once you reach 20% equity.

Key Assumptions

• 30-year fixed-rate mortgage assumed for all calculations.

• Property tax and maintenance costs increase with home appreciation.

• Does not include closing costs, realtor fees (typically 5-6% on sale), or moving costs.

• Does not account for mortgage interest tax deduction or capital gains exclusion.

• Investment returns are pre-tax and assume consistent annual returns (actual returns vary).

• Rent increases are applied uniformly each year.

Detailed Comparison

The Mortgage Calculator and the Rent vs Buy Calculator tackle different stages of the home-buying journey. A mortgage calculator focuses on what your monthly payment will look like once you have already decided to purchase, breaking down principal, interest, taxes, and insurance into a single payment estimate. The Rent vs Buy Calculator, on the other hand, steps back and asks the bigger question: should you buy at all?

While the mortgage calculator accepts a home price, down payment, and interest rate to output a monthly figure, the rent-vs-buy tool weighs opportunity cost, property appreciation, rent increases, and tax deductions over time. It produces a breakeven timeline showing how many years you need to own before buying becomes cheaper than renting.

Both tools are free, run entirely in your browser, and require no sign-up. Used together they form a complete housing affordability analysis: first determine whether buying makes sense, then drill into the exact mortgage payment you can expect.

When to Use Each Tool

When to Use Mortgage Calculator

Use the Mortgage Calculator when you have already decided to buy a home and need to estimate your monthly payment. It is ideal for comparing loan terms (15-year vs 30-year), seeing how extra payments reduce total interest, or stress-testing different interest rate scenarios before locking in a rate.

When to Use Rent vs Buy Calculator
