Warnings to note

  • This is a before-tax estimate and excludes local tax, legal, permit and accounting rules.
  • Expected sale price is an assumption, not a prediction or valuation.
  • The estimate is positive, but the profit margin is below 10%. Cost overruns, delays or a lower sale price could change the result.

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.

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.
Region settings
Region settings change defaults, labels and currency formatting only. They do not convert exchange rates or create country-specific results.

FAQs

What is house flipping profit?

It is the estimated sale proceeds after selling costs minus the purchase, renovation, financing, holding and other project costs entered.

Is this the same as a fix-and-flip calculator?

Yes. House flipping and fix-and-flip are similar labels for a short-term buy, renovate and sell scenario. The calculator uses the costs and sale price assumptions entered.

Why include a renovation contingency?

Renovation projects can overrun. A contingency shows how extra costs could affect the result.

What is break-even sale price?

It is the estimated sale price needed to cover the project costs and selling costs entered.

Does this include tax?

No. It is a before-tax estimate.

Does this include permits or inspections?

Only if you include them in other project costs.

Why do holding costs matter?

Longer projects can add insurance, utilities, rates or taxes, loan interest and other carrying costs.

Is ROI based on cash invested or total project cost?

This version uses estimated profit divided by total project cost and labels the result that way.

Is this investment advice?

No. It is a general scenario calculator based on the values entered, not financial, tax, legal, accounting, mortgage or investment advice.
