Sales Training ROI Calculator
Vozah's sales training ROI calculator helps you build a training business case you can defend. You enter the cost, then state your assumptions about the benefit. The calculator separates revenue, contribution, cash savings and time so nothing is counted twice. It runs in your browser, needs no signup and saves nothing.
Sales Training ROI Calculator
Runs in your browser. Nothing is saved.Opens on a hypothetical 10-rep team with zero assumed lift, so you see the cost before any benefit. Change every number to match your team.
Net contribution after cost
-$14,000
ROI on program cost
-100.0%
Payback
Not within the period
- Total program cost ($2,000 + $1,000 × 12 months)$14,000
- Incremental revenue credited (9 benefit months)$0
- Contribution at 60% margin$0
- Cash savings from stopped spend$0
- Break-even lift (what you would need to believe)1.30%
How the calculation works
| Step | Formula | Unit |
|---|---|---|
| Benefit months | analysis period − months before lift appears | months |
| Total program cost | one-time cost + program cost per month × analysis period | $ |
| Credited revenue per month | reps × revenue per rep × lift % × attribution % | $ / month |
| Incremental revenue | credited revenue per month × benefit months | $ |
| Contribution | incremental revenue × contribution margin % | $ |
| Cash savings | existing spend stopped per month × analysis period | $ |
| Net contribution | contribution + cash savings − total program cost | $ |
| ROI | net contribution ÷ total program cost × 100 | % |
| Payback | first month where cumulative contribution plus savings ≥ cumulative cost | month |
| Break-even lift | the lift % at which net contribution is zero | % |
The ROI formula follows the standard training ROI approach: net program benefits divided by program costs, × 100. It is described in the ROI Institute's ROI Basics chapter.
Four kinds of value, kept separate
- Incremental revenue is the top-line effect of your assumed lift. It is never treated as profit.
- Contribution is what that revenue is worth after variable costs. It's the only revenue-based figure in ROI.
- Cash savings is spending you will actually stop, such as a cancelled vendor contract. Planned savings that never leave the budget don't count.
- Time capacity is manager hours released minus rep hours spent in training. It's shown in hours and dollars but excluded from ROI. Time only becomes cash if you cut cost, and any revenue it produces is already in the lift.
Assumptions the model makes
- The lift applies equally to every rep in the program, starting after the delay you set.
- Attribution is a single percentage. If pricing, territories or hiring also change, lower it.
- Costs and benefits are not discounted for the time value of money.
- Quota carry, meaning the revenue each rep is expected to produce, enters only through "closed revenue per rep today." The calculator does not change quotas.
Worked example (hypothetical)
Click Load the worked example in the calculator to reproduce these numbers. The team and every input are invented for illustration. The 2% lift is an assumption, not a measured result.
Inputs: 10 reps; $1,000 per month program cost; $2,000 one-time setup; 12-month period; lift starts after 3 months; $40,000 closed revenue per rep per month; 2% assumed lift; 50% attributed to training; 60% contribution margin; $0 stopped spend; 4 manager hours released per month; 2 rep hours per rep per month; $75 and $50 loaded hourly costs.
- Total program cost: $2,000 + $1,000 × 12 = $14,000
- Credited revenue per month: 10 × $40,000 × 2% × 50% = $4,000
- Incremental revenue: $4,000 × 9 benefit months = $36,000
- Contribution: $36,000 × 60% = $21,600
- Net contribution: $21,600 + $0 − $14,000 = $7,600
- ROI: $7,600 ÷ $14,000 = 54.3%
- Payback: month 7. By then, cumulative contribution is $2,400 × 4 = $9,600 and cumulative cost is $2,000 + $7,000 = $9,000.
- Break-even lift: 1.30%. Below that lift, the program loses money under these assumptions.
- Time capacity (not in ROI): 4 manager hours − 20 rep hours = −16 hours per month, valued at $300 − $1,000 = −$700 per month
The zero-lift case
The calculator opens with the same inputs and 0% lift. Net contribution is −$14,000, ROI is −100%, and the program never pays back within the period. Break-even lift is still 1.30%. Before you sign, ask whether you have evidence for at least that much lift.
A fully loaded variant
Some ROI methods count participants' time as a program cost. To do that, add the rep time cost to the monthly program cost. In this example, that's 20 hours × $50 = $1,000, so enter $2,000 per month. Total cost becomes $26,000, net contribution becomes −$4,400, ROI drops to −16.9%, payback does not happen within 12 months, and break-even lift rises to 2.41%. If you use this variant, don't also count the time line separately.
Inputs and validation
- Every field needs a number of zero or more. Blank or negative entries show an error, and results are hidden until they're fixed.
- Lift, attribution and margin must be between 0 and 100.
- Reps, period and delay must be whole numbers. The period can run from 1 to 60 months, and the delay can't be longer than the period.
- With zero total cost, ROI shows as not defined instead of dividing by zero. Payback shows as immediate.
- If margin, attribution, reps, revenue per rep or benefit months is zero, no lift can cover the cost. Break-even lift then shows as not reachable.
How to choose a lift you can defend
Use evidence from your own team where you can. That could be a pilot group compared with a similar group that didn't get the training, or a before-and-after comparison that accounts for other changes. How to measure training effectiveness covers how to set that up. Sales training ROI walks through building the business case. Vendor claims, including Vozah's, are not evidence of what will happen on your team.
