Sales tool ROI calculator
Vendor ROI calculators take the best result any customer ever reported and apply it to your whole team. The number is always large and nobody believes it. This calculator starts from your own inputs, cuts every vendor claim before it counts, separates time saved from revenue gained, and shows how much of the ROI depends on the least certain assumption.

How to use it
- 1
Use your own baselines
Pull opportunity volume, win rate, and average deal size from your CRM for the segment the tool will serve. Use the vendor's numbers only for the claimed improvement, and label them as claims.
- 2
Haircut every claim
Cut each claimed improvement before it enters the formula. Half is a reasonable default rule of thumb; use a smaller cut only when you have pilot data from your own team.
- 3
Count only redirected time
Hours saved are worth something only if they go back into selling. Apply a redirection rate, and present the result as capacity unless a cost actually goes away.
- 4
Value revenue at gross margin
Extra deals are revenue, not profit. Multiply by gross margin so the benefit compares fairly with the tool's cost.
- 5
Run the sensitivity check
Remove the conversion lift and recalculate. If the ROI collapses, the case rests on the least certain assumption, and a pilot with a control group should come before a full purchase.
Frequently asked questions
How do you calculate ROI for a sales tool?
Add the value of redirected selling time and the gross margin on extra deals won, subtract the year-1 cost including implementation and internal time, and divide by the year-1 cost. Use your own baselines and cut vendor claims before they count.
What is a conservative haircut in an ROI calculation?
A reduction applied to a claimed benefit before it is counted, to allow for the gap between a vendor's best customers and your team. Half is a common rule of thumb; use your own pilot data to set it where you can.
Should ROI include time saved?
Include it, but label it as capacity rather than cash and only count the share that goes back into selling. Show the ROI with and without it so reviewers can see how much the case depends on it.
