📖 How To Use This Rent vs Buy Calculator

This tool compares the true long-term cost of renting versus buying, including opportunity cost of your down payment money, home appreciation, tax benefits from mortgage interest, and inflation on costs and rent.

Important Concepts

Opportunity Cost

The return you could have earned by investing your down payment money in the stock market instead of using it for a home purchase. This is one of the biggest hidden costs of buying.

Break-Even Point

The number of years you need to stay in the home before the total cost of buying becomes lower than renting. After this point, buying is usually the better financial decision.

🧮 How Costs Are Calculated

Monthly Ownership Cost (Buying)

Mortgage payment (P&I) + Property Tax/12 + Insurance/12 + Maintenance/12 + HOA/12 − Tax Savings from mortgage interest deduction

Monthly Renting Cost

Monthly Rent + Renter's Insurance + (Annual increases applied over time)

Net Cost of Buying

Includes opportunity cost on down payment + all ownership expenses − home equity built + home appreciation benefit when sold.

⭐ Key Factors That Influence the Decision

  • How long you plan to stay — Longer stays (7+ years) usually favor buying.
  • Home appreciation rate — Strong local markets make buying more attractive.
  • Investment returns — If you can earn high returns in the market, renting may be better financially.
  • Interest rates — Low rates favor buying; high rates increase the break-even period.
  • Tax situation — Higher tax brackets benefit more from mortgage interest deduction.
