Try a worked example
1. Set a common basis

Use the same team size for both options.

Include the full period you are committed to pay for.

All amounts in this currency. No conversion.

Option A

For an annual quote, divide the yearly seat price by 12.

Include migration, onboarding and your estimate of internal setup work.

Minimum seats and monthly extras

Use 0 if there is no minimum. We bill the larger of team size and minimum.

A flat total for add-ons, support, platform fees or expected usage.

Option B

For an annual quote, divide the yearly seat price by 12.

Include migration, onboarding and your estimate of internal setup work.

Minimum seats and monthly extras

Use 0 if there is no minimum. We bill the larger of team size and minimum.

A flat total for add-ons, support, platform fees or expected usage.

Blank optional fields count as zero. Leave them blank only when those costs do not apply. Inputs appear in the result URL; use amounts only, without confidential details.

How the estimate works

  1. Paid seats = the larger of team size and minimum paid seats.
  2. Monthly cost = paid seats × monthly seat price + other monthly costs.
  3. Estimated total = monthly cost × months + one-off costs.

Use the monthly equivalent of an annual quote, and include the full committed term. For a flat or usage-based quote, enter zero as the seat price and use its estimated monthly total as other monthly costs.

The calculation assumes constant rates and seats. Add your own estimate of training and migration to one-off costs. Include tax consistently if it belongs in your estimate; no tax rate is applied automatically.
