SaaS ROI calculator

Test whether a SaaS subscription can pay for itself. Turn team size, realistic time savings, labor cost, adoption, subscription fees, and setup cost into a first-year business case.

Model the first year

Use a conservative estimate of the time your team will actually save.

Loaded hourly cost can include salary, payroll taxes, benefits, and overhead. Adoption rate discounts the claimed time savings to a more realistic realized value.

First-year business case

Benefits and costs are annualized over 52 weeks and 12 months.

Transparent math

How SaaS ROI is calculated

Annual value equals team members × hours saved per user per week × 52 × loaded hourly cost × adoption rate. First-year cost equals 12 months of subscription fees + one-time implementation cost.

ROI is (annual value − first-year cost) ÷ first-year cost × 100. Break-even time saved reverses that formula to show the minimum hours each user must save per week for the first year to cover its cost.

What the result includes

  • Realized labor value after discounting for expected adoption
  • Twelve months of recurring subscription cost
  • One-time implementation, migration, or training cost
  • A separate payback test for the upfront setup investment

Keep the estimate honest

Use realized value, not vendor claims

Start with a conservative hours-saved estimate and lower it with the adoption rate. This model does not include revenue lift, avoided risk, taxes, financing, contract escalators, or the opportunity cost of implementation unless you add those costs to the setup figure. It is a planning estimate, not a purchase recommendation.

Check the price first

Use a source-linked subscription cost

ROI is only as reliable as the price entered. TierDrift records public SaaS plans with billing cadence, source links, and observation dates so you can start from a verifiable cost.
