General estimate only

This calculator provides general before-tax scenario estimates only. It is not financial, tax, legal, accounting, mortgage or investment advice. It does not predict sale price, replace contractor quotes, assess permits, guarantee financing or recommend a property.

How this house flipping calculator works

The calculator totals purchase, renovation, contingency, buying, financing, holding and other project costs. It then deducts selling costs from the expected sale price to estimate net sale proceeds and before-tax profit.

Purchase, renovation and contingency assumptions

Renovation contingency is added to the renovation budget before profit is calculated. The overrun scenario shows what happens if renovation costs rise by another contingency amount.

Financing, holding and selling costs

Financing interest uses a simple monthly interest estimate over the holding period. Holding costs cover recurring carrying costs while the project is owned. Selling costs are deducted from the sale price.

Break-even sale price

Break-even sale price estimates the sale price needed to cover project costs and selling costs. It depends on both fixed selling costs and the selling-cost percentage entered.

What this calculator does not include

This calculator does not predict sale price, replace contractor quotes, assess permits, model tax, guarantee financing, estimate legal risk or recommend any property. It is a general before-tax scenario calculator.

Key terms and assumptions

  • Total project cost: Project cost includes purchase, renovation, contingency, buying costs, financing costs, holding costs and other project costs.
  • Selling costs: Selling costs are deducted from expected sale price rather than included in project cost.
  • Financing interest: Financing interest uses a simple monthly interest estimate over the holding period.
  • ROI definition: ROI is estimated profit divided by total project cost in this version.
  • Overrun scenario: The overrun scenario adds another renovation contingency amount to show sensitivity to higher renovation costs.
  • General estimate: The calculator does not predict sale price, replace contractor quotes, model tax, guarantee financing or recommend a property.
