The Rent vs Buy Calculator compares the total cost of renting versus buying a home over your planned time horizon. This is one of the most important financial decisions you will make, and the answer depends on your specific circumstances — including how long you plan to stay, local market conditions, and your financial goals.

The analysis considers all costs of homeownership: mortgage payments, property taxes, insurance, maintenance (typically 1% of home value annually), closing costs (both purchase and future sale), and opportunity cost of the down payment. On the rental side, it factors in annual rent increases.

On the benefit side, homeownership provides equity building through both mortgage principal payments and home appreciation. The net buying cost subtracts the equity built from total buying costs, giving a true comparison against total rent paid.

The break-even point is the year at which buying becomes cheaper than renting on a cumulative basis. In most markets, this is typically 3-7 years, though it varies widely. In high-cost markets with slow appreciation, it can be 10+ years. In fast-appreciating markets, it may be just 2-3 years.

Key assumptions that affect the outcome: home appreciation rate (historical average is ~3-4% nationally), rent increase rate (typically matches inflation at 2-3%), and time horizon. If you plan to move within 2-3 years, renting is almost always cheaper due to high transaction costs of buying and selling.

Visual Analysis

How It Works

Total Rent = Sum of monthly rent over the period, with annual increases compounded

Total Buy Cost = Down Payment + Mortgage Payments + Taxes + Maintenance + Insurance + Closing Costs (buy + sell)

Equity Built = Future Home Value − Remaining Mortgage Balance

Net Buying Cost = Total Buy Cost − Equity Built

Savings = Total Rent − Net Buying Cost (positive means buying saves money)

Break-even is the year when net buying cost first falls below cumulative rent.

Understanding Your Results

A positive savings number means buying is cheaper over your time horizon. The break-even year shows when buying overtakes renting. If you plan to move before the break-even point, renting is the better financial choice. Equity built represents your wealth accumulation from homeownership, including both principal payments and appreciation.

Frequently Asked Questions

No. In high-cost markets, with short time horizons (under 3-5 years), or when investment returns exceed home appreciation, renting can be financially superior. The answer depends on your specific situation.

Generally 5-7 years to break even on transaction costs. In high-appreciation markets, it may be 3-4 years. In slow markets, 7-10 years. This calculator shows your specific break-even point.

The national historical average is about 3-4% annually. Use local data for better accuracy — some markets appreciate faster (5-8%) while others grow slowly (1-2%) or even decline.

Maintenance (1-2% of value annually), repairs, appliance replacement, landscaping, HOA fees, higher utility costs, and the opportunity cost of the down payment invested elsewhere.

This basic version does not include mortgage interest deduction. Since the 2017 tax law doubled the standard deduction, most homeowners no longer benefit from itemizing mortgage interest.

If you invest the down payment instead of buying (e.g., in index funds averaging 7-10% returns), the growth represents an opportunity cost of homeownership. This is significant for large down payments.

Rents typically increase 2-4% annually. Over 10+ years, rent compounds significantly — $2,000 rent growing at 3%/year becomes $2,688 after 10 years. This makes buying more favorable over longer periods.

A home is primarily shelter, not an investment. While it builds equity, returns historically trail the stock market. Buy for stability and lifestyle, not purely for investment returns.

Mortgage payments are 'forced savings' — you build equity whether or not you would otherwise save that money. For undisciplined savers, this is a significant behavioral benefit of homeownership.

Buying costs (2-5% of purchase price) and selling costs (5-8%, including agent commissions) are major factors. These transaction costs are a key reason why short-term homeownership is expensive.
