Software costs
Team Software Cost Calculator
Estimate team software cost across seats, plan price, billing cadence, and projected seat growth. Useful for budgeting SaaS subscriptions across a growing team. Per-seat price and seat count are user-entered; preset tables are intentionally avoided because vendor plans change.
Formula
- Monthly base = Seats * Price per seat + Add-ons monthly
- Annual base = Monthly base * 12
- Annual with discount = Annual base * (1 - Annual discount / 100) when cadence is Annual
- Year-2 seats = Current seats * (1 + Seat growth)
- Year-2 annual (informational) = Year-2 seats * Price per seat * 12 (without re-applying discount)
- Year-2 with discount = Year-2 annual * (1 - Annual discount / 100) when cadence is Annual
Examples
- 10 seats at $15/mo each, monthly billing, no add-ons: $150/mo, $1,800/year.
- Same on annual with 17% discount: $1,494/year.
- Growing from 10 to 12 seats (20% growth), annual with 17% discount: year-2 $1,792 with the discount applied.
When to use this calculator
- Annual SaaS budget for the whole team.
- Project year-2 SaaS cost from projected seat growth.
- Compare monthly vs annual billing on team subscriptions.
Common mistakes
- Forgetting add-ons. SSO, audit logs, and premium support often add 20-50% to base price.
- Skipping annual discount on tools your team uses continuously.
- Modeling growth linearly; teams often add seats in step changes (new hire batches).
Frequently asked questions
What does this calculator estimate?
Annual team software cost from seats, monthly price per seat, billing cadence, add-ons, and projected year-2 seat growth. The output is year-1 annual cost and year-2 projected annual cost.
Why no preset vendor list?
SaaS pricing changes too often to maintain as a reliable preset table. This calculator uses your own price-per-seat input so the result stays accurate without code updates. For AI-specific stacks, see the AI Tool Stack Annual Cost Calculator, which models multiple AI tools in one view.
What add-ons should I include?
SSO (often $5-$15/seat extra), audit logs, premium support, additional storage, advanced analytics, custom integrations. Sum all add-ons into the monthly add-ons field.
How does annual billing discount work?
Most vendors offer 10-25% discount on annual billing vs monthly. The default 17% reflects a common two-months-free pattern. Set this to your actual vendor discount.
Should I model seat growth?
Yes if you expect to add seats. A 20% annual seat growth on a $1,800/year stack adds about $360/year in year 2 at the same per-seat price. Compounding seat growth on multiple tools can outpace budget assumptions quickly.
Are taxes modeled?
No. US state sales tax on SaaS varies (some states tax SaaS, others do not). VAT applies in EU and UK. Currency conversion for non-USD billing is also not modeled. Add the appropriate tax rate to your final budget.
How does this compare to AI Tool Stack Annual Cost?
AI Tool Stack Annual Cost focuses on a small fixed set (3 tools by default) typical of an AI stack. Team Software Cost is generic per-seat math: pick any single SaaS vendor (Slack, Notion, Linear, Figma, GitHub) and model seats + growth + add-ons. Use AI Tool Stack for AI-specific budgeting; use this for the broader SaaS stack on a per-vendor basis.
What about per-feature pricing or usage-based billing?
This calculator models per-seat pricing only. Usage-based pricing (Sentry, Datadog, Vercel by traffic) requires different math. For those, model the monthly usage cost separately and add it to the team software annual total.

Sources and assumptions
- Per-seat pricing is the most common SaaS model; flat-fee and usage-based pricing exist but are not modeled here.
- Add-ons can include extra storage, premium features, audit logs, SSO, etc. These often differ by vendor; enter the total monthly add-on cost.
- Annual discount default 17% reflects a common two-months-free pattern.
- Seat growth projects year-2 cost. Real growth is rarely linear; treat the year-2 number as a planning band.
- NOT modeled: per-feature pricing, custom enterprise discounts, multi-year contracts, taxes, currency conversion, or onboarding/implementation services.

Team software cost is largely user-input. Vendor plan tables change too often to maintain as presets. This calculator uses your own price-per-seat input so it stays accurate without preset maintenance.
