Enterprise software licensing cost goes beyond the sticker price. Annual licence fee is the base; add 18-22% for annual maintenance/support, 5-10% for version upgrades, and implementation costs. Total cost of ownership over 5 years typically runs 2.5-4x the initial licence quote.
100 licences × 500/year each = 50,000 annual licence. 20% support = 10,000. 5% upgrade = 2,500. Total 62,500/year. Per-licence TCO: 625 vs 500 sticker. Over 5 years: 312,500. Many procurement teams only see the 50k/year quote; the full TCO is 25% higher before implementation.
SaaS vs perpetual licence comparison: SaaS includes support and upgrades in subscription (no separate line items). Perpetual licences seem cheaper year 1 but total cost over 5 years often matches SaaS once support contracts are added. SaaS wins on flexibility; perpetual wins on control.
Run it with sensible defaults
Using number of licences of 100, annual cost per licence of 500, support of 20%, upgrade of 5%, the calculation works out to 62,500.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Number of Licences, Annual Cost per Licence, Support %, and Upgrade % — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
How the math works
Total = licences × per-licence × (1 + support % + upgrade %). The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
What the score tells you
Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
100 × £500 £ + 20% support + 5% upgrade = $62,500.00.
