Buy vs Rent: The Full Cost Compared
The honest question isn't whether your mortgage beats your rent — it's what your total wealth looks like on each path over the years you'd actually stay, once you count what the down payment could have earned, what selling really costs, and what a home really costs to keep up. Enter your numbers for the net position on each path, the year buying overtakes renting, and what's driving it.
These move the result more than anything else — how long you stay most of all.
Pre-filled with realistic values — they default to reality, not to whatever makes buying look best.
Renting has fewer cost levers — the comparison assumes you invest the difference each month.
These decide whether buying gives you any tax benefit at all — for most middle-class buyers in 2026, it's essentially zero.
The 30-year picture
Total wealth on each path at the end of every year — home equity net of selling costs plus any invested surplus (buy), versus the down payment and monthly surplus invested (rent). The higher number is ahead; the highlighted row is where buying overtakes renting.
| Year | If you buy | If you rent + invest | Difference | Ahead |

What's driving it
How this is calculated: each figure is total wealth on that path over your stay — for buying, home equity net of selling costs plus any invested surplus (after capital-gains tax); for renting, the down payment, closing costs, and monthly surplus invested (after tax). Whichever path is cheaper in a given year invests the difference, so the comparison is symmetric. Resale is taken net of selling costs at the home's appreciated value, and maintenance, property tax, insurance/HOA, and PMI (when down payment is under 20%) are all counted. The horizon and mortgage run 30 years; appreciation, rent growth, and investment returns use long-run averages — real outcomes vary. Tax picture (2026): the standard deduction is $16,100 (single) / $32,200 (married filing jointly), per the IRS. The SALT deduction cap follows current law — $40,400 through 2029, reverting to $10,000 in 2030 as written (Congress could extend it) — so the modeled buy-side tax benefit steps down in the projection's fifth year. The high-earner SALT phaseout begins above ~$505,000 of income, above this calculator's range, so it isn't modeled. Default figures current as of June 2026. These are transparent assumptions, not forecasts — adjust them to your situation. Not financial, tax, or real-estate advice.
