Rent vs. Buy Calculator
Compare the true cost of renting versus buying a home over time
What is the Rent vs. Buy Calculator?
Buying a home is often described as "building equity" and renting as "throwing money away." Neither framing is quite right. The Rent vs. Buy Calculator runs the actual numbers for your situation: your local housing prices, rent costs, mortgage rates, expected home appreciation, and opportunity cost of the down payment. The result is a break-even point — the number of years after which buying becomes cheaper than renting. This is the tool to use before making one of the biggest financial decisions of your life, and it's especially useful in high-cost markets like San Francisco, New York, or Seattle where the math is genuinely close.
How Does It Work?
The calculator compares total costs of renting against total costs of buying over a specified period, adjusting for equity built, appreciation, investment returns on the down payment, and tax deductions.
Net Cost to Buy = Mortgage Payments + Taxes + Insurance + Maintenance − Equity Gained − Appreciation
Net Cost to Rent = Monthly Rent × Months + Foregone Investment Return on Down Payment
Monthly Rent and rent escalation rate are the core rental inputs. Purchase Price, down payment, interest rate, property tax rate, and annual maintenance costs drive the buying side. The calculator also factors in how the down payment could grow if invested in index funds instead.
How to Use CalciHub's Rent vs. Buy Calculator
1. Enter your local home price and expected rent for a comparable property.
2. Input down payment amount, mortgage rate, and loan term.
3. Add property tax rate, home insurance cost, and estimated annual maintenance.
4. Enter your expected home appreciation rate and investment return rate.
5. Set how long you plan to stay in the home.
6. Tip: The break-even point is usually 4–7 years in most US cities. If you plan to move sooner, renting typically wins on pure financial grounds.
A Quick Example
Sarah is deciding between renting a two-bedroom apartment in Austin for $2,200/month or buying a similar home for $380,000 with 10% down at 6.8% interest.
Monthly mortgage payment: ≈ $2,236. Add property taxes ($480/month), insurance ($120/month), and maintenance ($316/month). Total monthly cost to own: ≈ $3,152 vs. $2,200 to rent.
The calculator factors in equity accumulation and 3.5% annual home appreciation. Break-even point: approximately 6 years.
If Sarah plans to stay in Austin for 7+ years, buying starts making financial sense. If she might move in 3 years, renting is the smarter call.
Frequently Asked Questions
No. Whether buying or renting is better depends on your timeline, local price-to-rent ratios, and personal circumstances. In cities where home prices are very high relative to rents, renting and investing the difference can outperform buying over a 5–7-year horizon. The calculator gives you the actual answer for your specific numbers.
