When this calculator helps

  • Capex-heavy SaaS (implementation, migration, integration consulting).
  • Tools where the value ramp takes 60-90 days (sales tools, CRMs).
  • Justifying a multi-year commitment to a CFO.

When to look elsewhere

  • Subscriptions with zero implementation cost, payback is immediate if monthly net value is positive.
  • Tools where value is non-linear (e.g. a security tool that prevents a single $1M breach).

Frequently asked questions

What's a good payback period for SaaS?

Under 12 months is excellent, 12-18 months is normal for enterprise SaaS, 18+ months requires a strong strategic case to defend.

Should I include opportunity cost?

If the upfront capital could earn 5%+ elsewhere (e.g. money-market yield), add that as a discount to year-1 net. For most SMB decisions this is rounding error.
