Average seats = (current + future seats) ÷ 2. First year = monthly seat price × average seats × 12 + (monthly add-ons + usage) × 12 + setup + training hours × hourly cost.

Enter your working assumptions
Use the vendor's current quote and your realistic 12-month team size. For a flat plan that already includes users, set both seat counts to 1 and put separately billed users in add-ons.
Reproduce the estimate before using it.
Seat count is assumed to change evenly during year one. Price and monthly extras stay constant; setup and training occur once. These are planning assumptions, not measured vendor costs.
$29 per seat, 5 → 8 seats, $30 add-ons, $20 usage, $500 setup, and 16 training hours at $35/hour: $2,262 + $600 + $1,060 = $3,922. These are illustrative inputs, not a product quote.
With eight seats for the whole second year and unchanged prices, recurring cost is $29 × 8 × 12 + $600 = $3,384. This excludes new implementation work and any price increase at renewal.
If all eight seats are required from day one, set both seat counts to eight; the first-year example becomes $4,444. Set the counts to five for a no-growth case ($3,400). Keep these scenarios separate from actual cash payments.

What this estimate does not include
Add taxes, foreign-exchange costs, payment fees, contract minimums, and exit costs when applicable. Annual prepayment changes cash timing: do not add the same subscription a second time. If seats or usage change unevenly, calculate a separate monthly schedule.
