The Only Real Estate Flip Calculator You'll Ever Need (Free Google Sheets)

The Only Real Estate Flip Calculator You'll Ever Need (Free Google Sheets Template)

As a real estate investor, I've analyzed hundreds of potential flips. The biggest time sink?
Rebuilding the same spreadsheet calculations over and over.

I finally built a simple 6-input Google Sheets template that gives me profit, ROI, and max
allowable offer in under 30 seconds. And it's completely free.

What it calculates automatically:

• Total Investment (purchase + rehab + holding costs)
• Gross Profit (ARV minus total investment)
• ROI percentage (returns on your cash invested)
• Max Allowable Offer using the 70% rule

The formula that matters most:

Profit = ARV - Purchase Price - Rehab Budget - (Holding Months × Monthly Costs)

That's it. Six inputs, one instant result.

Why the 70% rule matters:

If a property will be worth $250,000 after repairs, never pay more than:
$250,000 × 70% = $175,000 minus $40,000 rehab = $135,000 max purchase price

What's your go-to metric for analyzing flips? I'm partial to ROI over 20% with a 4-month max hold.
