Three steps to model multi-year software TCO
Lock a common evaluation horizon
Evaluate both vendors across the same seat count and 1-to-5 year contract term using effective monthly rates.
Include platform, onboarding, and add-on costs
Capture base platform fees, mandatory implementation packages, premium support, integration connectors, and annual renewal uplifts.
Price data migration and contract exit
Model a one-time exit and export cost so low year-one promotional pricing does not mask high switching friction.
Multi-year TCO formula and contract assumptions
Year n recurring cost = 12 × (seats × monthly seat price + monthly platform fee) × (1 + annual increase ÷ 100)^(n − 1) + annual extras. Total = all yearly recurring costs + setup + exit.
Worked 3-year SaaS cost example
For 10 seats at $25 per seat/month ($0 platform fee), year-one subscription cost is $3,000. With a 5% annual renewal uplift, subscription cost rises to $3,150 in year two and $3,307.50 in year three. Adding $600/year in annual extras ($1,800 over 3 years), $1,500 one-time onboarding, and $500 exit migration yields a 3-year TCO of $13,257.50 ($36.83 effective monthly cost per seat).
Licensing assumptions and model boundaries
This calculator models nominal multi-year contract cash outflows, not a live vendor price quote. Seat count remains fixed across the selected horizon. The annual percentage increase compounds on per-seat and monthly platform fees starting in year two, while annual extra costs remain flat. One-time setup and one-time exit costs are added once. Usage overages, mid-term seat expansions, taxes, and time-value discounting are not calculated automatically.

Software pricing, renewal caps, and TCO modeling FAQ
How should I compare annual upfront billing with monthly billing?
Enter the effective monthly rate for each quote. For example, if a vendor quotes $240 per user per year, enter $20 as the monthly price per seat. The calculator compares total nominal spend over the term.
Which fees compound when I enter an annual price increase?
The annual price increase percentage compounds on the per-seat subscription and monthly platform fee starting in Year 2. Annual extra costs stay flat unless you adjust them manually.
What belongs in Annual extra costs vs One-time setup cost?
Put recurring support tiers, sandbox environments, SSO add-ons, or annual compliance packages in Annual extra costs. Put initial onboarding, data migration, and initial training in One-time setup cost.
Why include an exit cost when evaluating a new software purchase?
Exporting historical records, rebuilding workflows, and running parallel systems during a future transition require time and vendor assistance. Pricing exit friction upfront prevents vendor lock-in surprises.
Does this calculator upload or store our vendor pricing quotes?
No. All TCO calculations execute strictly inside your browser session. No pricing inputs are sent to any server. Use Export comparison CSV to save your scenario locally.
