Rent vs. Buy Calculator

Compare monthly cash and projected net worth when renting versus buying — under the same starting resources, allocated differently.

Neither strategy is assumed to win. Results are arithmetic under your assumptions, not advice.

How this works

The 1% figure is only a starting-dollar helper. After entry, this amount grows with general inflation — not with home-price appreciation.

Legal fees, inspections, land-transfer taxes, and similar upfront buyer costs.

    Buyer net worth includes net realizable home equity after estimated selling costs, plus investments.

    Positive = buying ahead · Negative = renting ahead

    Mortgage payoff — final payment means the last mortgage payment occurs at that point; mortgage cash requirements fall the following month.
