Rent vs Buy Calculator

Introduction

This Rent vs Buy Calculator compares the cost of leasing against purchasing a home over a horizon you choose, such as seven years. It weighs monthly rent against PITI, maintenance, closing costs, appreciation, and equity buildup so you can see whether ownership wins on dollars in your expected tenure, not on generic always-buy advice.

Who this calculator is for

Renters with stable jobs who might relocate use this page to test break-even tenure before they write offers. Owners renewing a lease in a hot market run the same math to see if buying now beats two more years of rent growth. The calculator fits households that have a down payment range and a realistic stay length, not infinite horizon speculation.

Maximum affordable price from income alone is the House Affordability Calculator. Simple rent as a percent of pay is the rent affordability tool. Monthly PITI detail sits in the Mortgage Calculator.

What it estimates

The renting path sums rent payments, often with an annual rent increase assumption, plus renters insurance. The buying path includes down payment, closing costs, recurring PITI, maintenance, tax and insurance escalation, and subtracts equity from amortization and appreciation at sale minus estimated selling costs. Net cost or net wealth at the horizon year is compared side by side.

Tax deductions for mortgage interest and property tax, capital gains exclusion, PMI, HOA special assessments, and opportunity cost of down payment invested in markets are simplified or optional. Local rent control and prop tax caps vary; defaults are generic.

Inputs explained

Align the stay length with your actual plan, not the longest mortgage term.

• Monthly rent: Current lease payment excluding utilities you would pay either way.
• Purchase price and down payment: Target home price and cash equity at closing.
• Interest rate and loan term: Fixed-rate assumptions on the first mortgage.
• Property tax and insurance: Annual amounts converted to monthly in PITI.
• Maintenance: Often one percent of home value per year as a rule of thumb.
• Horizon years: Expected years until sale or move, such as seven.
• Appreciation and rent growth (optional): Annual percent changes for sensitivity.

How to read the results

Look for the year renting and buying cross if the tool shows a break-even timeline. At seven years buying may show lower net cost if appreciation and principal paydown outweigh closing costs and maintenance. If buying loses at year seven but wins at year twelve, tenure is the decision variable.

Opportunity cost matters: down payment invested elsewhere at a realistic return can tilt toward rent even when headline math favors buy. Run conservative appreciation and include one percent maintenance before you treat output as proof.

Worked example

Rent $2,200 monthly with three percent annual increases totals roughly $195,000 in rent over seven years before renters insurance. Buy at $400,000 with ten percent down and 6.75% thirty-year: PITI near $2,850 including tax and insurance assumptions, plus maintenance near $333 monthly at one percent of value per year. Closing costs near $12,000 upfront.

After seven years with modest three percent annual appreciation, sale proceeds might return down payment, principal paid, and appreciation minus six percent selling costs. If net buyer cost beats renter cost by $15,000 to $40,000 depending on appreciation, buying wins on this horizon; at zero appreciation renting may stay ahead because of early-year interest and closing costs.

Practical use cases

Test job offer in a new city with a five-year horizon. Compare buying a smaller home now versus renting and buying later with saved down payment. Model rate lock now against six months more rent while saving.

Investors should not use this homestead tool; use the Rental Property Calculator. After choosing buy, confirm cash with the Down Payment Calculator.

Limitations and related tools

Emotional benefits of ownership, school districts, and landlord hassle are not priced. ARM loans, refi mid-horizon, and HELOC draws mid-ownership are not fully modeled. Tax benefit depends on itemizing versus standard deduction; the calculator may omit tax or use simplified brackets.

How It Works

1. Enter rent side. Type current monthly rent and optional annual rent increase percent.
2. Enter buy side. Add purchase price, down payment, rate, tax, insurance, and maintenance estimate.
3. Set horizon and growth. Choose years you expect to stay and appreciation or rent growth assumptions.
4. Compare net cost. Calculate and read seven-year or custom horizon totals for rent versus buy including equity at sale.

Formula and methodology

The Rent vs. Buy Calculator uses this identity for the scenario you enter. A bank, payroll system, or tax program may round on a 360-day year or average daily balance, so a statement can differ by a small amount.
