Rent vs Buy Calculator – Make the Right Housing Decision

Deciding whether to rent or buy a home is one of the most important financial decisions you can make. Both options have advantages and costs, and the right choice depends on your personal finances, lifestyle, and long-term goals. The Rent vs Buy Calculator helps you compare the total costs of renting versus buying a property over time, allowing you to make an informed decision.

Why Using a Rent vs Buy Calculator Matters

• Financial clarity: Understand how much you will spend on rent versus mortgage payments.
• Long-term planning: See how buying a home can build equity over time.
• Budgeting: Factor in costs like property taxes, maintenance, insurance, and rent increases.
• Decision-making: Compare scenarios quickly and make smarter housing choices.

Key Parameters and Formulas

The calculator requires the following inputs:

• Home Price (P): The total cost of the property you are considering.
• Down Payment (DP): Initial amount you pay when buying, usually a percentage of P.
• Loan Amount (L): L = P − DP
• Interest Rate (r): Annual mortgage interest rate (%)
• Loan Term (t): Number of years for mortgage repayment
• Monthly Rent (R): Current monthly rent amount
• Property Taxes, Insurance, Maintenance: Annual costs to maintain home

Formulas Used

• Monthly Mortgage Payment: M = L × [r/12 × (1 + r/12)^12t] / [(1 + r/12)^12t − 1]
• Total Cost of Buying: TC_buy = (M × 12 × t) + DP + Taxes + Insurance + Maintenance − Home Value Appreciation
• Total Cost of Renting: TC_rent = (R × 12 × t) + Rent Increases

How the Calculator Works

1. Enter the home price, down payment, loan term, interest rate, and additional annual costs.
2. Enter your current rent and expected rent increases over time.
3. The calculator computes the monthly mortgage payment and total costs for buying and renting.
4. Compare the total costs side by side to determine which option is financially better over your desired time frame.

Example Scenario

Problem: You are considering a $300,000 home with a 20% down payment, 4% interest rate, 30-year mortgage. Monthly rent for a similar property is $1,500. Property taxes, insurance, and maintenance total $5,000/year.
Step 1: Calculate loan amount: L = 300,000 − 60,000 = $240,000
Step 2: Calculate monthly mortgage payment using formula: M ≈ $1,145
Step 3: Calculate total cost over 5 years:
TC_buy = (1,145 × 12 × 5) + 60,000 + (5,000 × 5) = $145,700
TC_rent = 1,500 × 12 × 5 = $90,000
Step 4: Comparison: Renting is cheaper in the short term, but buying builds equity.
