The advertised seat price is where license cost starts. This tool reconciles the quote with what you will pay: base seats by class, required add-ons and edition upgrades priced on the seats they touch, usage fees spread across seats for comparison, minimum seat commitments and renewal uplift. It also lists shelfware (bundled modules you do not use) as negotiating leverage. Its figures feed TCO (total cost of ownership) and Contract Risk, where the full picture comes together.
Every formula, constant and a worked example are in the published method.

Each line's share of the hidden annual. A single recurring line above 80% of the recurring license cost is flagged, because it likely has the wrong pricing type.

What it means · the platform seat-equivalent is a comparison figure
The quoted seat price covers the base seat. A production-ready license also carries required add-ons, edition (tier) upgrades, usage-based charges, support packages, minimum seat commitments and renewal uplift, and this model separates each one. Across 150 billable seats the $125 quote becomes $185 once required per-seat modules and edition upgrades are added, and $185 per seat-equivalent once usage fees are spread across seats. That is a 48% premium, worth $108K a year. The hidden annual amount is not automatically waste. It is the part of platform cost the quote did not show.
That hidden annual breaks down as $108K required add-ons, $0 tier upgrades, and $0 usage fees. Each is negotiated differently. Co-term add-ons (end them on the same date as the master agreement) and lock their rates, confirm the scope of edition upgrades, and cap or commit usage fees. Keeping the three apart keeps each lever visible.
Storage / Archival, Premium Support / TAM are bundled but unused, known as shelfware. Use them to challenge whether the tier fits, request credits, secure implementation concessions or negotiate future module access. It is not recoverable savings: count it as cash only if the vendor confirms a price reduction in writing.
Use this to budget the real platform baseline and to negotiate before you sign: get the price of every required module and edition upgrade in writing, co-term add-ons to the master agreement, cap usage fees, and lock the rate for the seats you expect to add within eighteen months. Treat the quote as the vendor's opening position.
