SaaS True Cost Open calculator

ROI & payback

SaaS ROI calculator

Short answer

Plug in a tool's monthly cost and the monthly value it returns, and see ROI %, annual net gain, and the break-even tipping point. Built for procurement defending a renewal to finance.

Simple ROI model. Assumes value-per-month is steady. For bursty value (e.g. seasonal sales tools), divide annual value by 12 first.

When this calculator helps

  • Defending a SaaS renewal to finance or procurement.
  • Modeling whether a higher-tier upgrade pays for itself.
  • Comparing tool A vs tool B on a value-not-cost basis.

When to look elsewhere

  • Tools where value is impossible to quantify (security, compliance, brand).
  • Pilots under 30 days, too little data on actual value delivered.
  • Bundled deals where individual-tool value can't be isolated.

Frequently asked questions

What ROI is good for a SaaS tool?

Procurement teams typically want 200%+ first-year ROI for new SaaS, and 100%+ for renewals. Lower than 50% is a strong signal to renegotiate or replace.

Should implementation cost be included?

Yes for year-1 ROI. Many tools pay back fine in year 2+ but year-1 ROI dies once you add migration, training, and integration consulting.

How do I estimate monthly value?

Three approaches: (1) hours saved × loaded labor cost, (2) revenue directly attributable to the tool, (3) cost of the next-best alternative (or zero tool) minus this tool's cost.
