Rent vs. Buy Calculator

Should you rent or buy? It's one of the most personal financial questions out there — and the answer is different for everyone. This calculator cuts through the emotion and gives you the actual 5–10 year cost comparison.

What This Calculator Compares

It calculates the true total cost of renting (rent payments + renter's insurance + forgone investment opportunity) versus buying (mortgage, taxes, insurance, maintenance, transaction costs, equity built) over a given timeframe.

How to Use This Calculator

1. Enter the home purchase price and down payment.
2. Enter mortgage rate, term, annual property tax, insurance, and maintenance estimates.
3. Enter the monthly rent for an equivalent home.
4. Enter expected home appreciation rate and investment return rate (for the down payment if renting).
5. Set the time horizon (how many years you'll compare).
6. Click Calculate to see total cost for each option.

Key Factors That Favor Buying

• You plan to stay 5+ years (enough time to recover transaction costs)
• Local home prices are appreciating
• Mortgage payment is close to or lower than rent
• You value stability and building equity

Key Factors That Favor Renting

• You may move within 2–3 years
• Local home prices are high relative to rents (high price-to-rent ratio)
• You can invest the down payment at a higher return than home appreciation
• You want flexibility and no maintenance responsibility

Example Comparison (5-year horizon)

Buy: $400,000 home, 10% down, 7% rate | Rent: $2,400/month equivalent

• Total buying costs (mortgage + taxes + maintenance − equity gained): ≈ $142,000
• Total renting costs (rent + insurance − invested down payment growth): ≈ $157,000
• Result: Buying wins by ~$15,000 over 5 years in this scenario

Common Mistakes to Avoid

• Ignoring transaction costs — Buying and selling a home costs 8%–10% (agent commissions, closing costs). Short timelines rarely recoup this.
• Forgetting the opportunity cost of the down payment — That $40,000 could grow in the market if you rented instead.
• Assuming home price always rises — Home prices can stagnate or fall in certain markets. Model multiple scenarios.
• Comparing mortgage payment to rent only — True homeownership costs include taxes, insurance, maintenance, and repairs.

Frequently Asked Questions

What is the price-to-rent ratio?

Divide the home price by annual rent. A ratio above 20 typically favors renting; below 15 typically favors buying. Between 15–20 is a gray zone where individual factors matter most.

How many years before buying makes financial sense?

Generally 3–5 years. Under 3 years, transaction costs usually make renting cheaper. Over 5 years, buying almost always wins due to equity buildup and appreciation.

Is building equity the same as investing?

Not exactly. Home equity is illiquid and undiversified. Buying is often a good long-term wealth builder, but it's not the same as investing in a diversified stock portfolio.

What about rent increases?

Rent typically rises 3%–5% annually. A fixed-rate mortgage payment never changes (though taxes and insurance do). This makes buying more attractive over longer time periods.

Can I rent out a room if I buy?

Yes — house hacking (renting out part of your home) dramatically improves the buy side of this equation. Use our Rental Property Calculator to model the income.
