How long do I need to stay to make buying worth it?
It varies by market, but the calculator's break-even year shows the point at which buying overtakes renting for your inputs — often 5–7 years is a common range.
From the tool guide Ask a follow-upDoes this include property tax and insurance?
Yes, you can enter both, plus estimated annual maintenance.
From the tool guide Ask a follow-upWhat is the opportunity cost of a down payment?
The investment return you give up by putting that money into a home instead of, for example, index funds — the calculator models this.
From the tool guide Ask a follow-upIs this financial advice?
No, it is a planning estimate based on the numbers you enter — consult a financial advisor for personal advice.
From the tool guide Ask a follow-upDoes it account for tax deductions?
It focuses on cash costs; mortgage interest deductibility varies by country and situation and is not automatically applied.
From the tool guide Ask a follow-upWhat if home prices fall?
Try a lower or negative appreciation rate to see how the comparison changes.

Buying a home is not just the mortgage payment versus the rent — it includes a down payment, closing costs, property tax, maintenance, insurance and eventual selling costs, weighed against what your money could earn if invested instead of tied up in a down payment. This calculator takes your rent, home price, mortgage rate and term, expected home appreciation and investment return, and works out the total cost of each path over your chosen number of years.
How to use it, step by step
- Enter your monthly rent and the home price you are comparing.
- Enter the mortgage rate, term and down payment.
- Add property tax, maintenance and expected appreciation.
- Read the net cost comparison and break-even point.
Tips from the guide
- Include realistic maintenance costs — 1% of home value per year is a common rule of thumb.
- Do not ignore closing and selling costs; they can offset several years of savings.
- Run the numbers at a few different time horizons, since buying usually favours longer stays.
- Compare against your actual likely investment return, not an optimistic guess.
Common mistakes to avoid
- Comparing only the monthly mortgage payment to rent, ignoring tax, maintenance and insurance.
- Assuming home prices always rise at the same rate.
- Forgetting the opportunity cost of the down payment and closing costs.
Who uses it
- First-time home buyers. Decide whether buying makes financial sense right now.
- Renters considering a move. Compare the true cost, not just the headline monthly payment.
- Financial planners. Model different rate and appreciation scenarios for clients.
How to ask a question people can answer
A good thread on the Rent vs Buy Calculator saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
