Is your form tool paying for itself?
Plug in leads, close rate, customer value, and cost. See payback period and return over any horizon, so the next form budget conversation takes 30 seconds.

How it works
ROI is a story, not a number, and this calculator tells both
Form ROI is the horizon over which the tool pays for itself, plus how much surplus it generates on top. It's the number you bring to the next budget review, not to brag, but to steer.
The unglamorous truth: most lead-capture tools pay back in the first month. Where ROI gets interesting is the compound effect: small A/B test lifts on the form itself, stacked over 12 months, often outrun the tool cost by 30×+.
Methodology
The four lines of arithmetic
Formula
ROI = (Leads × Rate × Value × Months − Cost × Months) / (Cost × Months) × 100
- Leads × Rate
- Customers per month.
- × Value
- Revenue per month.
- × Months
- Horizon (typical: 12). Stretches revenue AND cost.
- − Cost × Months
- Subtracts the total tool spend over the horizon.
Budget tips
How to avoid the nice-number trap
- 1
Include the full cost, not just the tool. Time your team spends on setup, maintenance, and response triage is real money.
- 2
Use conservative close rates. If marketing says 30% and sales says 18%, the ROI number you want to believe uses 18%.
- 3
Break payback into months, not years. Investors and CFOs both want to know when money stops leaving and starts arriving.
- 4
Run the calc per form, not just per account. A pricing form and a trial-signup form have wildly different economics.
- 5
ROI below 200% is marginal. Above 500% the number stops being credible, so double check your inputs.
Run the math once. Run the form forever.
