What House Flip Profit Calculator does and how it behaves

A proposed flip is evaluated as one complete buy-renovate-hold-sell transaction. Enter the purchase price, planned renovation spending, ownership-period holding costs, expected selling costs, and projected after-repair value (ARV). The calculator compares the expected resale value with those project costs to estimate profit. It is most useful for checking whether a deal still works after expenses beyond construction are included. The common mistake is treating ARV as guaranteed proceeds. ARV is a projection, and the actual sale price may be lower.

How the result is produced

1

Build the project cost

The purchase price, renovation costs, and holding costs describe what it takes to acquire, improve, and carry the property. Selling costs account for the expense of exiting the deal. Together, these entries form the cost side of the flip. Costs left out of the entries are also left out of the resulting profit estimate.

2

Compare cost with ARV

After-repair value supplies the projected resale amount for the completed property. Projected profit is the ARV remaining after the entered purchase, renovation, holding, and selling costs are deducted. Changing ARV tests sale-price risk, while changing renovation or holding costs shows how overruns or delays affect the deal's expected margin.

Good uses

  • Screening a property before making an offer by comparing its asking price and estimated rehabilitation budget with a supportable after-repair value.
  • Revising a flip budget after contractor bids arrive to see whether higher renovation spending leaves enough projected profit to continue.
  • Stress-testing a delayed resale by increasing total holding costs or reducing ARV, then comparing the weaker scenario with the original deal estimate.

Limits and checks

  • ARV is an estimate of the property's finished resale value, not a promise that a buyer or appraiser will accept that amount. Review the result again with a lower ARV.
  • Holding expenses depend on time. If an estimate is monthly, convert it to the expected project total unless the field explicitly requests a monthly amount and holding duration.
  • Projected flip profit is not automatically taxable profit, cash-on-cash return, or cash available at closing. Financing, taxes, unpaid obligations, and omitted transaction expenses can produce different figures.

Common questions

Which expenses belong in holding costs?

Use costs caused by owning the property between purchase and resale, such as financing charges, insurance, property taxes, utilities, routine maintenance, and security when applicable. Enter project totals rather than monthly estimates unless the field says otherwise. Do not repeat an expense already included under renovation or selling costs, because double-counting understates profit.

Does the projected profit equal my taxable profit?

No. This estimate compares the entered project costs with projected resale value; it does not establish tax basis, deductible treatment, income classification, or tax due. Those amounts can depend on facts outside the calculator and on current tax rules. Keep invoices and closing records, and use appropriate tax guidance or professional advice for the actual transaction.
