Calculate net profit after holding and selling costs. The paid version adds five-deal comparison and sale-price/hold-time downside scenarios with a maximum purchase price at your target.

Current sample workbook view. Read the buyer guide for definitions, setup and limitations.
Potential gross is a scenario, not money earned. Set targets you can justify, account for implementation costs, and compare actual results with your saved starting point. Annualized amounts use an unchanged monthly run-rate; no income or timeline is promised.
The free Lite version is the single-deal analyzer. The full version adds a five-deal compare and a pricing guide.
Analyzer: modeled net, ROI, break-even, holding limit and a verdict against your target profit.
Compare: up to five deals, each with its own target. Incomplete deals cannot return a healthy verdict.
Downside: base, 5% lower sale price, and 5% lower sale plus 30 extra holding days. Includes a pricing guide and PDF buyer guide.
Purchase price, recon, fees, and what you'll realistically sell it for.
Days to sell, holding cost per day, and your pack/fees.
Net profit, ROI, break-even and a GO / PASS against your target profit.
Compare it to other cars, or walk. Every day past your estimate costs you — the tool shows how much.
Use your own product mix and enter zero for required categories with no activity. Review every unavailable result.
