Most ROI calculators stop at "time saved." That is a mistake. Automation generates value in three distinct categories, and you need to capture all of them to build an accurate business case.

Identify every manual task being automated. Multiply the time per occurrence by frequency per month, then by the fully loaded hourly cost of the person doing it. "Fully loaded" means salary plus benefits, payroll taxes, and overhead — typically 1.3x to 1.5x the base hourly rate.

Manual processes carry error rates of 1% to 5%. Every error has a downstream cost: rework time, customer compensation, compliance penalties, or lost revenue from a frustrated client who does not come back. Quantify how many errors occur per month and what each one costs to fix.

Faster processes generate more revenue. A lead response that drops from four hours to 30 seconds converts at a measurably higher rate. An invoice that goes out same-day instead of next-week gets paid faster, improving cash flow. These numbers are real and trackable.

After deploying automation across dozens of SMB clients, these are the benchmarks I consistently see across four major categories.

I see these errors in nearly every automation business case that crosses my desk.
