Why does it not include revenue improvement?

Because we cannot substantiate it. Calculators that multiply an assumed conversion lift by your revenue produce impressive numbers that no one can verify. This counts only what you can check against invoices.

What is the biggest driver of the difference?

Headcount growth. Per-seat pricing adds cost every time you hire; a flat plan with unlimited users does not. Over three years with a team doubling, that single difference dominates everything else.

Does this include migration cost?

No, and that counts against us. Migration takes two to four weeks of parallel running and some retraining. Neither is in the model.

ROI calculator — three-year platform cost

Q: How is this ROI calculation done?

It compares three years of platform cost as a team grows. The stack side is a flat $28,000 a year plus $3,400 per person for seat-priced tools. The Marketing Titan side is a flat plan with unlimited users. Only cost is modelled.

What this does and does not model

read before quoting it

Cost only. No claimed revenue lift.

Most vendor ROI calculators multiply an invented conversion improvement by your revenue and produce an enormous number. We are not doing that, because we cannot substantiate it and neither can they.

What is counted

A flat platform component of $28,000 a year plus $3,400 per person for seat-priced tools, against a flat Marketing Titan plan with unlimited users.

What is not counted

No conversion lift, no revenue increase, no time savings. Also no migration effort and no retraining — both real costs on our side of the ledger.

Where it could be wrong

If you negotiated hard, or run fewer seat-priced tools than the model assumes, the gap narrows. Substitute your own per-seat figure and re-read it.

“Any calculator that multiplies a made-up conversion lift by your revenue will tell you what you want to hear. That is what it was built to do.”
Why this one only counts cost

The cost of a platform is decided by the team you will have, not the one you have.
