Fix and flip calculator.
The full round trip. Purchase, rehab, the cost of the money, the carry, the cost of selling, and what is left.
Rehab is financed in full and the purchase is advanced at the rate below, so the remainder is your down payment. Interest is charged on the drawn balance, since rehab is released in draws rather than handed over at closing. Return on cash counts the down payment, which is why it is a believable number rather than a headline one. The rate below is an assumption you can change rather than a quote, since pricing is set by credit, experience and the deal; buy-side closing near 2% and about 6% to sell are typical market costs rather than my terms.
Net profit
Thin but workable. You are $20,500 above the 70% rule, and still clear $30,058 if the rehab holds at budget.

This sends the numbers above straight to me. You get a written term sheet inside 24 to 48 hours, and a straight answer if it does not work.
How to read it
What the number means.
Most flip calculators stop at after repair value minus purchase minus rehab and call the difference profit. That number has never once been the profit. It ignores the cost of the money, the months of carry, and the six percent or so that leaves on the way out, and those three together are usually the difference between a deal worth doing and a deal that pays you for a job.
This one counts them. Return on cash is calculated against the money you actually put in rather than against the purchase price, which is why it comes back as a believable figure rather than a headline one.
If the answer is thin, the honest response is usually a lower offer rather than a more optimistic finished value. The offer is the only variable you fully control.
Questions
About the arithmetic.
What holding costs should I include?
Taxes, insurance, utilities and anything else that runs whether or not work is happening. They are entered separately from the loan interest because they continue at the same rate whether the project is moving or stalled, which is exactly what makes them dangerous.
How long should I assume for the hold?
Longer than the contractor says. The carry line is the one that punishes optimism, and adding two months to a five month assumption is the cheapest stress test available.
Why is my return on cash lower than I expected?
Usually because it is measured against the cash in the deal rather than against the purchase price, and because the sale costs are counted. Both are real, and a number that excludes them is a number that will not survive a closing statement.
What if the finished value is a guess?
Then the whole answer is a guess. Work the finished value out from comparable sales first with the ARV calculator, then come back.
Method
Where these numbers come from.
How to underwrite a fix and flip before you call a lender
The full pre-application check, in the order a lender will run it. If a deal survives this, it will survive underwriting.
The 70% rule in house flipping, and the deals where it lies to you
The 70% rule is a filter, not an underwriting model. Here is what it assumes, and the four situations where following it loses money.
Holding costs: the line item that quietly eats the profit
Holding costs are small every month and decisive over a project. They are also the number investors most reliably leave out of the model.
Other tools
The rest of them.

This is an estimating tool. It runs arithmetic on the figures you enter using the assumptions stated above, and changing an assumption changes the answer. The result is not a quote, an approval, an appraisal, a valuation, or a prediction of what a property will sell for, and it does not commit anyone to lend. Costs, taxes and market conditions vary by location and change over time. Check the numbers that matter against your own contractor, agent and professional advisers before you commit to a deal.
When the numbers work
Get it priced.
A calculator cannot see your property. Send the deal and you get written terms in 24 to 48 hours, with no credit pull to get a number.
