How We Calculate SaaS Costs

What goes into an estimate, the formulas we use, and where the limits are.

Where the data comes from

We compile plan prices, usage limits, and extra fees from vendors' public pricing pages and documentation. Each tool page shows when its pricing was last checked, only when we have recorded that date. Vendors change prices often, so treat every figure as a starting point and confirm it on the vendor's site before you buy.

Prices that are quote-based (“contact sales”) are not something we can know. We do not guess them.

How an estimate is built

  1. 1

    Plan price

    The listed price of the plan, at the monthly or annual-equivalent rate you choose. Per-seat plans are multiplied by your seat count, respecting any minimum seats.

  2. 2

    Overages

    If your usage exceeds a plan's limit and we have a documented overage rate, we charge the excess at that rate. If the limit is a hard cap, we move you to the cheapest plan that fits.

  3. 3

    Recurring documented fees

    Extra monthly costs that apply when a documented trigger is met (for example, premium apps or add-ons). These are added to the monthly estimate.

  4. 4

    One-time costs

    Implementation, setup, and similar costs are shown separately. They are never added to a monthly figure.

Hypothetical example (not a real vendor)

A plan lists $20 per seat per month. You enter 5 seats. A documented add-on adds $10/mo, and there is a $500 one-time setup fee.

Monthly estimate = ($20 × 5) + $10 = $110/mo. The $500 setup fee is shown separately as a one-time cost.

Comparisons and alternatives

Comparison and alternatives pages use each tool's advertised price plus its recurring documented fees, on illustrative default assumptions. We only call one option cheaper when the estimated monthly gap is at least 5%. Tools in different categories are not like-for-like, and those pages say so.

What our estimates are not

  • They are not quotes, and they are not guaranteed to match your invoice.
  • We have not measured their accuracy against real customer bills, so we do not publish an accuracy percentage.
  • Taxes, currency conversion, negotiated discounts, and promotions are not included unless stated.
  • Usage-based costs depend entirely on the numbers you enter.
