When Buying Wins
- You plan to stay 5+ years (closing cost recovery)
- Local price-to-rent ratio under 20
- You have stable income and emergency fund
- Mortgage payment is similar to or less than rent
- Strong appreciation market
When Renting Wins
- You may move within 3-4 years
- Price-to-rent ratio is over 25 (very expensive market)
- You have better investment opportunities for the down payment
- Job/income uncertainty
- You want flexibility without maintenance responsibility
Break-Even Rule of Thumb
Many financial advisors cite 3-5 years as the break-even point where buying becomes cheaper than renting. In expensive markets it's often 7-10 years. The calculator above shows the exact crossover point for your specific numbers.

Rent or Buy? The Break-Even Math
Zillow's 2023 Rent vs. Buy analysis across the 50 largest U.S. metros found renting was cheaper than buying in 47 of 50 metros on a monthly-payment basis — a reversal from 2019 when buying won in 39 of 50. The median monthly mortgage payment on a typical home hit $2,188 versus $1,747 for a typical rental, a 25% premium that the 7%+ mortgage rates amplified.
The crossover point depends on holding period. The New York Times buy-vs-rent calculator model (based on Case-Shiller appreciation + rental-parity theory) finds that at 6.8% rates, 3% rent inflation, and 3.5% annual home appreciation, a median buyer needs to stay 7.4 years to break even versus renting and investing the difference — up from 3.9 years in 2019.
Transaction costs dominate short-hold scenarios: closing costs average 2-5% of purchase price on the buy side, and agent commissions (typically 5-6% under pre-2024 norms, shifting after the NAR settlement) plus repairs eat into proceeds when selling. On a $400,000 home, that's $8,000-$20,000 in closing plus $20,000-$24,000 in sale-side costs — $28,000-$44,000 in round-trip friction that must be recouped before ownership pays off.

Methodology & Assumptions
This calculator implements standard formulas drawn from primary-source authorities. Values are point-in-time estimates; consult a licensed professional for high-stakes decisions. See the per-input definitions and source citations below.
How this works
Computations are deterministic and run client-side — no inputs leave your
browser. Formulas are derived from
standard published formulas for the calculator's domain (mortgage,
taxes, energy, conversions, etc.). When the underlying agency publishes
updated rates or thresholds we refresh defaults and update the page's
lastmod timestamp.
