Rent vs Buy: The Complete Financial Analysis
The decision to rent or buy is one of the biggest financial choices you'll make. This calculator helps you compare the true cost of each option by accounting for factors that simple online calculators often miss: home appreciation, the opportunity cost of your down payment, maintenance expenses, and how rents increase over time.
What makes this calculator different?
Most rent vs buy comparisons only look at your monthly payment. This calculator includes the wealth-building side of buying: equity gained through mortgage paydown, home appreciation, and the opportunity cost of having your down payment tied up in real estate instead of invested in the stock market. It also accounts for maintenance costs, property taxes, and annual rent increases.
When does buying become cheaper than renting?
In many markets, you need to stay in a home for 5-7 years before buying becomes financially superior to renting. Before that point, the transaction costs (down payment, closing costs, and maintenance) outweigh the savings. However, if you're planning to stay long-term and home prices are appreciating, buying can be significantly cheaper and builds equity instead of paying a landlord.
Should I include opportunity cost?
Yes. Your down payment is money that could be invested in the stock market or bonds. By including a realistic investment return rate (historically 8-10% for stocks), you see the true financial cost of locking that capital into real estate. This is why a larger down payment sometimes looks worse in a rent vs buy analysis—but it can reduce your monthly payment.
