What Is Your Housing Really Costing Your Wealth?

Housing is almost everyone's largest expense — and almost no one has calculated what it's truly costing them in wealth-building terms. The monthly payment is only part of the story. The real cost of housing includes the opportunity cost of capital tied up in a down payment, equity that could be invested elsewhere, interest paid that disappears, and the hidden costs of ownership that renters never see. The Housing Opportunity Cost Calculator doesn't just compare rent vs. buy — it models the full 10-year financial picture for your specific situation. It calculates the true cost of ownership (mortgage interest, property taxes, insurance, maintenance, and transaction costs) against the true cost of renting (rent payments, foregone appreciation), then computes the wealth differential: what you'd have if the capital tied up in your home were instead invested in the market. This isn't an argument for renting or buying. It's a tool for understanding the real number — the dollar figure your housing decision is costing or contributing to your net worth over the next decade. Most people who run this calculation are surprised by how different it is from their intuition.
