At a glance
How the subscription cost calculator works
- 1 Enter the per-seat monthly price and how many seats you need.
- 2 Add the annual-billing discount (many vendors give ~2 months free for paying yearly).
- 3 Set expected seat growth so the 3-year figure reflects your team scaling.
- 4 See monthly, discounted annual, and 3-year totals — plus what annual billing saves.
Monthly = Price × Seats. Annual = Monthly × 12 × (1 − discount%). 3-year cost compounds seat growth each year.
Frequently asked questions
How much do you save with annual billing?
Most SaaS vendors offer 10–20% off for annual billing — often framed as "2 months free". On a $15/seat plan for 20 seats, a 17% discount saves roughly $600 per year.
How do I budget for subscription growth?
Project seat growth (new hires, expansion) year over year. This calculator compounds your growth rate across three years so your budget reflects scaling rather than today's headcount.
What is per-seat pricing?
Per-seat (or per-user) pricing charges a fixed amount for each person who uses the software. Total cost = price per seat × number of seats × billing period.
Monthly vs annual billing — which is better?
Annual billing is cheaper if you're confident in the tool and your seat count is stable. Monthly billing costs more but keeps flexibility if you might churn or change tools.
