ROI & payback
SaaS payback period calculator
Short answer
Enter monthly cost and monthly net value, get the exact number of months until break-even. Pairs with the ROI calculator when you need to defend a longer payback to finance.
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.
