Real estate investment calculators.

Successful real estate investing starts with accurate numbers. Whether you're evaluating your first fix-and-flip deal or underwriting your hundredth, having reliable calculators eliminates guesswork and protects your margins.

Our free tools cover the four core calculations every house flipper needs: After Repair Value (ARV) estimation, Maximum Allowable Offer (MAO) using the 70% rule, rehab cost estimation, and comprehensive profit analysis. Each calculator is designed by investors, for investors.

The ARV calculator helps you determine what a property will be worth after renovations by analyzing comparable sales in the area. The MAO calculator applies the industry-standard 70% rule to tell you the most you should pay. The rehab cost estimator breaks down renovation expenses room by room so you don't miss hidden costs. And the flip profit calculator ties everything together with holding costs, financing, and closing costs to show your true net profit and ROI.

These tools are completely free — no signup, no credit card, no catch. For investors who want to take their analysis to the next level, Vortonic's full platform offers AI-powered ARV modeling, automated deal screening, and real-time market analytics across every market in the country.
