Methodology
The per-line formula behind every cell of the calculator, the source list, the refresh cadence, and what this site will not infer.
Per-line formulae
// formula.monthly_total{"gateway_fee": "vendor-specific (see below)","per_call": "calls × published per-million rate", // tiered where the vendor tiers"egress": "calls × 5 KB × $0.09/GB", // AWS-equivalent"add_ons": "portal_seats × $30 + mTLS_uplift", // illustrative; varies per vendor"ops_fte": "fte × $14,583/mo", // $175k loaded / 12"support": "(gateway_fee) × support_multiplier" // 0 / 3 / 10 percent}
The annual-at-commit cell applies a flat 20% discount to the annual list. This is the defensible anchor; real EA discounts will vary. See /pricing-models/annual-commit-and-ea.

For every line above, the calculator renders quote. We do not fabricate a number to fill the cell. This is the site's editorial position.
Sources
Vendor pricing pages and primary docs. Each numeric claim links inline with a forest-green tick. The full registry lives in src/data/sources.json and the per-vendor source URL is on every vendor reference page.
Refresh cadence
Quarterly. The current verification stamp is 20 June 2026. Vendor pricing changes between refreshes are added to the pricing change log on the date we record them.
Currency, region, tax
All figures USD list. Region uplifts are modelled where vendors publish them. Tax (VAT, GST, US state sales tax) is not included.
