Anything that is one search away stays free: the calculators, the benchmarks, the thresholds. We charge only where the tool does real work on your numbers, the kind of math a buyer would otherwise pay an advisor for.
Every tool is verified against the current SBA SOP 50 10 8 and the live Procedural and Policy Notices. When a rule changes, the tools change, which is more than most free SBA calculators can say.
