Quick start
- Open the Rent vs. Buy Calculator.
- Enter monthly rent and expected rent increase.
- Use the first example, "Seven-year compare: $2,100 rent vs $420,000 home for 7 years", if you want to see a filled-out estimate before entering your own values.
- Calculate, read the formula line, then copy the result only after the amounts, percentages, time periods, or assumptions look right.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Compare renting and buying over a specific number of years.
- Test rent growth, appreciation, and selling cost assumptions.
- Include basic mortgage, tax, insurance, and maintenance estimates.
- Screen whether time horizon changes the answer.
What this calculator is for
The Rent vs. Buy Calculator compares renting with buying and selling after a chosen number of years. It is built for testing assumptions, not declaring one choice right for everyone.
Good fit examples: Compare renting and buying over a specific number of years. Test rent growth, appreciation, and selling cost assumptions.
What to enter
Finance estimates are sensitive to small input changes. Check whether a field expects a monthly amount, annual amount, dollar value, or percent before calculating.
- Enter monthly rent and expected rent increase.
- Enter home price, down payment, mortgage rate, years, tax, insurance, maintenance, appreciation, and selling cost.
- Use the number of years you realistically expect to stay, because short and long horizons can give very different answers.
Example walkthrough
Try the calculator example: Seven-year compare: $2,100 rent vs $420,000 home for 7 years. The example result is Buying lower by about $35,454.79.
- $2,100 rent versus a $420,000 home over seven years compares projected rent cost with buying cash outflow.
- The calculator estimates home value, remaining loan balance, and sale proceeds, then compares net buying cost with total rent cost.
Formula and steps
In plain language: The calculator projects rent with annual increases, estimates buying cash outflow, estimates sale proceeds after appreciation and selling costs, then compares net buying cost with rent cost. For the default example, projected rent is about $193,094.05. Net buying cost is about $157,639.26 after estimated sale proceeds, so buying is lower by about $35,454.79 in this simplified model.
If the estimate looks surprising, check the formula and inputs before using the answer in a budget, comparison, or planning note.
How to read the answer
Start with the headline result. Then read the supporting lines to see what made the number larger or smaller, such as rates, time periods, costs, taxes, fees, discounts, or contributions.
- Buy minus rent is the final gap between estimated buying cost and rent cost.
- Net buying cost subtracts estimated sale proceeds from buying cash outflow.
- Estimated sale proceeds depend heavily on appreciation, selling costs, and remaining loan balance.
Common mistakes to avoid
Most bad finance estimates come from mixing rates, terms, monthly amounts, and annual amounts. The other common mistake is using a planning estimate as if it were a final quote.
- Do not ignore opportunity cost, taxes, PMI, HOA, repairs timing, moving costs, or lifestyle flexibility.
- Do not assume appreciation is guaranteed.
- Do not compare a short stay with a long stay using the same conclusion.

FAQ in plain language
When should I use the Rent vs. Buy Calculator?
Use it when you want to test the exact inputs on this page: Compare renting and buying over a specific number of years. Test rent growth, appreciation, and selling cost assumptions. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Rent vs. Buy Calculator inputs mean?
Monthly rent means today's rent before the calculator applies the annual rent increase. Annual rent increase means the percent rent grows each year in the renting side of the comparison. Home price and down payment means the purchase price and upfront cash used to estimate the loan amount. Mortgage rate and compare over years means the annual loan rate and the number of years you expect to keep the home before the modeled sale. Property tax, insurance, and maintenance means the recurring ownership costs added to the mortgage payment. Appreciation and selling cost means the home-value growth assumption and sale-cost percent used to estimate sale proceeds.
What is the Rent vs. Buy Calculator doing with my numbers?
In plain language: The calculator projects rent with annual increases, estimates buying cash outflow, estimates sale proceeds after appreciation and selling costs, then compares net buying cost with rent cost. For the default example, projected rent is about $193,094.05. Net buying cost is about $157,639.26 after estimated sale proceeds, so buying is lower by about $35,454.79 in this simplified model.
How should I read the Rent vs. Buy Calculator answer?
Read the headline first, then compare total rent cost with net buying cost. Estimated sale proceeds and remaining loan balance explain why the buy side changes so much with appreciation, selling cost, and time horizon.
What does this estimate leave out?
This does not include taxes, investment returns on cash, repairs timing, moving costs, HOA, PMI, local rules, opportunity cost, or personal flexibility needs. Before making a real housing decision, also add PMI, HOA dues, closing costs, tax effects, investment opportunity cost, repair timing, moving costs, school/work constraints, and the value of flexibility.
What should I double-check before copying the result?
Check the stay length, rent-growth assumption, mortgage rate, down payment, property tax, insurance, maintenance percent, appreciation rate, selling cost, and whether the built-in 30-year mortgage assumption fits your scenario.
What does buy minus rent mean?
Buy minus rent is net buying cost minus total rent cost. If it is negative, the calculator shows buying lower by the difference. If it is positive, the calculator shows renting lower by the difference.
