Rent vs. Buy Calculator
Execute a comprehensive 30-year lifecycle financial comparison between purchasing a home and renting, determining the exact break-even timeline in years.
• Break-Even Horizon: In the early years, buying has high upfront closing and transaction fees. Over time, equity buildup and fixed mortgage payments overcome compounding rent inflation.
• Opportunity Cost: Capital difference (down payment vs. security deposit) is modeled growing in alternative investments at your designated return rate.

Your Information
Buying is cheaper if you stay for 4.9 years or longer. Otherwise, renting is cheaper.
Based on your upfront capital of $110,000, estimated 30-yr mortgage of $2,573/mo, property tax, maintenance, and 5% investment return.
Average Monthly Cost Trajectory (Buying vs. Renting)
Notice how buying starts high due to closing fees, drops steadily as equity grows, while renting rises with rent inflation.

Rent vs. Buy: The Core Financial Trade-offs
Deciding whether to rent or buy is rarely just a comparison between a monthly rent check and a monthly mortgage payment. It involves evaluating upfront friction, ongoing maintenance, equity growth, tax deductions, and investment opportunity costs.
1. Transaction Friction
Buying a home involves 2%–5% in buyer closing costs and 6%–8% in seller closing commissions. This is why buying rarely makes sense for horizons under 3–5 years.
2. Fixed Principal & Inflation Hedge
A 30-year fixed mortgage locks in your principal & interest payment for 3 decades, whereas rental rates historically compound upward at 3% to 5% annually.
3. Investment Opportunity Cost
A $100,000 down payment invested in a balanced stock index fund at 7%–10% compounding return represents a significant alternative wealth engine that renters can leverage.

Rent vs. Buy Calculator — Frequently Asked Questions
Q1 What is the Rent vs. Buy break-even point? ▾
The break-even point is the number of years you must live in a purchased home for the total net financial cost of buying (including closing fees, mortgage interest, property taxes, and maintenance minus equity gains) to become less than the total net cost of renting (including compounded rent and opportunity cost of capital).
Q2 Why is buying usually more expensive in the first 1 to 3 years? ▾
In the initial years, buyers pay heavy upfront closing costs (2%–5% buyer fees upon purchase and 6%–8% seller agent commissions upon sale), and early mortgage payments consist almost entirely of interest rather than principal equity.
Q3 How does opportunity cost affect the decision to rent or buy? ▾
When you buy, significant liquid cash is locked in your down payment and closing costs. If you rent, that capital can be invested in the stock market or other assets to generate compound growth over time.
Q4 How does inflation affect renters vs. homeowners? ▾
A fixed-rate mortgage locks in your principal and interest payment for up to 30 years, protecting against inflation. Renters, conversely, face compounded annual rent hikes that steadily increase monthly housing costs.
Q5 What ongoing homeownership costs are often overlooked? ▾
Prospective buyers often forget property taxes (1%–2% of home value/yr), home insurance, HOA fees, and routine maintenance/repairs (budgeted at 1%–2% of home value annually).
