Real Estate Investor Calculators
Every calculator here is free, ungated and works without an email address. Each one shows its arithmetic rather than a single flattering number, because the figure that matters is usually the one the industry rounds off.
01
Sizing up a deal
What it is worth, what it needs, and what you can pay for it.
- ARV CalculatorAfter-repair value as a range, with comp disagreement shown.
- Maximum Allowable Offer CalculatorThe 70% rule against the offer your own costs support.
- BRRRR CalculatorCapital recovered and cash flow after the refinance, side by side.
- Fix & Flip CalculatorProfit, and how far the ARV can miss before it disappears.
- Scope of Work CalculatorA rehab budget built line by line instead of guessed at.
- Cash Offer CalculatorA cash offer against listing — net proceeds, not headline price.
