RENT VS BUY

Rent vs Buy Calculator

Compare renting with buying a similar home over the number of years you expect to stay. The model includes upfront cash, the loan, rent, ownership costs, future home value, selling costs and money that could stay invested.

YOUR ASSUMPTIONS

Compare two complete housing paths

1. Home, down payment and loan

Use the purchase price and rent for homes that are reasonably comparable in location, size and quality.

2. Renting and how long you expect to stay

3. Future assumptions

These are assumptions, not forecasts. Small changes can materially change the result.

SIDE-BY-SIDE RESULT

See what builds wealth and what is simply paid out.

Loan principal is not treated as a pure cost because it reduces debt and builds home equity.

HOW THE COMPARISON WORKS

Give both paths the same resources.

The comparison avoids a common bias: assuming the renter invests every saving while the buyer never invests anything after the loan becomes cheaper or finishes.

Calculation sequence

  1. Start both paths with the same available housing cash: the larger of the buyer's and renter's upfront requirements.
  2. Each path pays its own upfront requirement. Any unused starting cash is invested.
  3. For each month, calculate the full housing outflow for buying and renting.
  4. Use the larger monthly outflow as the shared housing budget. The cheaper path invests the difference at month end.
  5. Grow the home value, rent, other housing costs and investments using the assumptions you entered.
  6. At the selected horizon, subtract selling costs and the remaining loan from the home value, then compare net wealth.

FAQ

Questions about renting versus buying

Does the calculator treat the full loan payment as a cost?

No. Interest is a financing cost, while principal reduces the loan balance and becomes part of home equity.

Why does the renter invest unused upfront cash?

Both paths start with the same available housing cash. If renting needs less cash upfront, the difference remains available to invest instead of disappearing from the comparison.

Can the buyer invest money later too?

Yes. Every month, whichever path has the lower housing outflow invests the difference. That includes the buyer after the loan is repaid if buying becomes cheaper.

Does this calculator tell me whether I should buy?

No. It compares financial paths under your assumptions. Stability, flexibility, location, maintenance responsibility and other life factors still matter.
