Buying a home is often seen as a cornerstone of financial success, while renting is sometimes viewed as a temporary solution. However, when it comes to actual costs and long-term wealth-building, the decision to buy or rent isn’t always straightforward. That’s where a Buy vs Rent Calculator becomes essential.
This comprehensive tool evaluates the true cost of both options — considering mortgage payments, rent increases, property taxes, maintenance, and opportunity costs — to help you make an informed decision that best suits your financial goals and lifestyle.
Buy vs Rent Calculator
🏡 What Is a Buy vs Rent Calculator?
The Buy vs Rent Calculator is a financial decision-making tool that compares the long-term cost of purchasing a home versus continuing to rent. It factors in multiple elements like:
- Monthly rent and expected increases
- Home purchase price and mortgage terms
- Property taxes and maintenance costs
- Insurance and closing fees
- Investment returns on savings or opportunity costs
The result helps answer the question:
“Is it cheaper to rent or buy over the next X years?”

Follow these steps to get accurate results:
1. Enter Your Monthly Rent
Input your current rent and expected annual increase (typically 2–4%).
2. Input Home Purchase Price
Enter the price of the home you’re considering.

A general rule is 1% of the home’s value annually.
7. Set Investment Return Rate
What return could you earn by investing the money you would’ve spent on buying?

- Total cost of renting vs. buying over your time horizon
- Breakeven point in years
- Equity accumulation
- Net gain/loss of each option
🧮 Buy vs Rent Formula Breakdown
While the calculator uses multiple complex variables, here’s a simplified version of the formulas it follows:
Cost of Renting:
pgsqlCopyEditRent Cost = Sum of (Monthly Rent × 12) over each year + Investment returns lost on security deposit or cash reserves Cost of Buying:
pgsqlCopyEditBuying Cost = Mortgage Payments + Property Taxes + Maintenance + Insurance + Lost Investment Returns – Home Appreciation – Equity Accumulated The tool compares both paths, adjusts for inflation and rent hikes, and shows which is more financially favorable over the given period.
📘 Example Calculation
Let’s say you’re deciding between renting or buying in a mid-sized city.
- Monthly Rent: $1,800
- Annual Rent Increase: 3%
- Home Price: $350,000
- Down Payment: $70,000 (20%)
- Interest Rate: 6.0%
- Loan Term: 30 years
- Property Tax: 1.2% annually
- Insurance & Maintenance: $3,000/year
- Investment Return on Cash: 5%
- Time Horizon: 7 years
Result:
- Cost of Renting Over 7 Years: ~$163,000
- Cost of Buying Over 7 Years: ~$185,000
- Net Difference: Renting saves ~$22,000
In this case, renting appears cheaper in the short term. However, if you plan to stay longer or expect home prices to rise, buying may become the better option.
