๐ก Rent vs Buy Calculator
Make the rent-or-buy decision with real numbers. Compare the total cost of renting against buying over your expected time horizon to see which saves you more.
What is this tool?
The decision to rent or buy a home is one of the largest financial choices most people will ever make, and it is far more complex than simply comparing a monthly rent payment to a monthly mortgage payment. Buying involves a down payment, closing costs, property taxes, insurance, maintenance and repairs โ while renting offers flexibility and requires no up-front capital. The right choice depends on how long you plan to stay, local market conditions, interest rates and your overall financial situation.
This calculator takes a holistic view of both options. On the buying side, it accounts for the down payment, mortgage payments, property taxes and maintenance costs over the time horizon you specify. On the renting side, it simply totals the monthly rent over the same period. The result shows you which option costs less in total over your chosen timeframe.
While no calculator can capture every factor โ such as the emotional value of ownership, the flexibility of renting, or future home price appreciation โ this tool gives you a solid quantitative foundation for the decision. All calculations happen locally in your browser.How it works
The total cost of renting is calculated as Total Rent = Monthly Rent ร 12 ร Years. This is the straightforward sum of all rent payments over the time horizon.
The total cost of buying is the sum of several components: the down payment (an up-front cost), all monthly mortgage payments over the period, annual property taxes, and annual maintenance costs. The mortgage payment uses the standard amortisation formula. The calculator totals all buying costs and compares them against the total rent. The difference tells you which option is less expensive in pure dollar terms. Note that this simplified model does not account for home price appreciation, the tax deductibility of mortgage interest or the opportunity cost of investing the down payment โ it provides a clear baseline comparison.How to use

Frequently Asked Questions
Is it always better to buy if you plan to stay long-term?
Not necessarily. Even over long periods, buying can be more expensive than renting if home prices are very high relative to rents (a high price-to-rent ratio), if property taxes and maintenance costs are significant, or if mortgage rates are high. Use the calculator with local numbers to see which is truly cheaper in your market.
What costs does this calculator include for buying?
It includes the down payment, all mortgage payments (principal and interest), property taxes and maintenance over the time period. It does not include closing costs, homeowners insurance, HOA fees or the potential return on investing your down payment elsewhere. For a more complete picture, add those costs manually.
Does the calculator account for home price appreciation?
No. This simplified model compares out-of-pocket costs only. If home prices rise, the buyer may build equity that offsets some of the costs, which would make buying more favourable. Conversely, if prices fall, buying becomes more expensive. For a full analysis, consider potential appreciation separately.
How long do I need to stay for buying to make sense?
The break-even point (the number of years at which buying becomes cheaper than renting) varies enormously by location and market conditions. In some markets it is 3โ5 years; in others it can be 10 or more. Run the calculator with your local numbers and your expected stay to find your personal break-even.

Tips & Advice
The rent-versus-buy decision is as much about lifestyle as it is about money. Renting gives you flexibility to move for career opportunities, avoids the risk and hassle of maintenance, and frees up your down payment for other investments that may earn a higher return. Buying builds equity over time, protects you from rent increases and offers the emotional satisfaction of ownership, but it also concentrates your net worth in a single illiquid asset. When using this calculator, be honest about how long you realistically plan to stay โ transaction costs alone (closing costs to buy and agent commissions to sell) often total 6โ10 percent of the home value, meaning you need several years just to break even on those costs. Property taxes and maintenance are ongoing costs that many first-time buyers underestimate: budget at least 1โ2 percent of the home value per year for these. Finally, remember that a mortgage payment is fixed for decades while rent typically rises with inflation, so buying becomes relatively more attractive the longer you stay.
