Rent vs Buy: The Complete Guide
The rent vs buy decision is one of the most significant financial choices you will make. The conventional wisdom that buying is always better than renting is wrong. The right answer depends on your specific numbers, time horizon, local market conditions, and opportunity cost of your capital.
This calculator accounts for the factors most people miss: the opportunity cost of your down payment (what it would earn if invested in the stock market instead), rising rent costs over time, home appreciation, equity buildup through mortgage payments, and the full cost of ownership including maintenance, taxes, and insurance.
When Buying Usually Wins
Buying tends to win when you plan to stay for 5+ years (amortizing the high upfront costs), when the price-to-rent ratio is below 15 (meaning buying is relatively cheap compared to renting in your area), when mortgage rates are low relative to investment returns, and when you are in a market with strong appreciation potential.
When Renting Usually Wins
Renting tends to win when you plan to move within 3-5 years (not enough time to offset buying costs), when the price-to-rent ratio exceeds 20 (very expensive to buy relative to rent), when you can invest the down payment at high returns, or when you are in an overheated market with risk of price correction.
The Real Estate Investor Perspective
For real estate investors, this calculator is also useful for analyzing whether to buy a primary residence or continue renting while investing your capital in rental properties. Many successful investors rent their primary residence and deploy their capital into cash-flowing investment properties where the returns are higher.
