Rent vs Buy Calculator — Find Your Breakeven Year

The single most important variable is how long you'll stay in the home. Buying carries large one-time costs — closing fees (3–6% of price), moving, furnishing, immediate repairs — that are spread over your ownership period. Sell after 2 years and those costs eat any equity gain; sell after 10 years and they become trivial.

A reasonable rule: don't buy unless you're confident you'll stay 5+ years. Job stability, relationship status, family plans and city affordability all factor in. The Rent vs Buy Calculator computes the breakeven year explicitly — if it's longer than your realistic stay, renting wins regardless of how 'cheap' the monthly payment looks. Buying a home you sell in 3 years is one of the most expensive financial mistakes Americans routinely make.

The mortgage payment is only the start. Annual property taxes range from 0.4% (Hawaii) to 2.5% (New Jersey) of home value. Homeowners insurance adds $1,000–$3,000/yr. Maintenance averages 1% of home value annually — a $400k home means $4,000/yr in repairs, replacements and upkeep over time. Add HOA fees ($200–$700/mo for many condos), and total monthly cost is often 40–60% above just principal and interest.

The Rent vs Buy Calculator factors all of these in. The most common mistake is comparing 'rent vs mortgage payment' — that comparison favours buying every time and is wrong. The right comparison is total monthly cost of buying (PITI + maintenance + opportunity cost of down payment) vs total monthly cost of renting (rent + renter's insurance). On that basis, renting is often cheaper than people assume — especially in high-cost cities and at high mortgage rates.

A $100k down payment isn't 'free' just because it stops being cash and becomes equity. That same $100k invested in a diversified index fund at 7% real return grows to ~$200k in 10 years — money you don't have if it's locked in your home. Home appreciation has historically averaged 3–4% real (after inflation), meaningfully lower than equity returns over the same period.

This doesn't mean buying loses — leverage works in homeowners' favour. A $100k down payment on a $500k house benefits from appreciation on the full $500k, not just the $100k. But the math only works if you stay long enough for appreciation to outpace the opportunity cost. The calculator runs both sides honestly — investing the down payment in markets vs building equity in real estate — and shows the net wealth difference at each year. The answer is often closer than either camp claims.

Some legitimate reasons to buy even when renting wins financially: stability for kids' schools, ability to renovate to your taste, no risk of landlord-mandated moves, psychological security of ownership, hedge against rent inflation in your specific market. These are real values that don't appear on a spreadsheet — and for many people they're worth a 5–10% financial penalty.

The corresponding reasons to rent even when buying narrowly wins: career flexibility (the average US job tenure is now under 4 years), unwillingness to deal with maintenance, freedom to relocate for opportunities, ability to invest the down payment instead. The Rent vs Buy Calculator gives you the financial truth; you make the lifestyle call. The worst path is buying because 'renting is throwing money away' — that aphorism has cost more young families than any other piece of financial folk wisdom.
