SaaS ROI Calculator
A SaaS ROI calculator shows whether a software tool pays for itself. Enter what the tool costs and the value it creates (time saved, revenue gained), and it returns your return on investment (ROI %), net annual gain and payback period.
Total yearly subscription + add-ons.
Optional — any additional measurable benefit.

How the saas roi calculator works
- 1 Add up the true annual cost of the software (subscription + add-ons + fees).
- 2 Estimate the value it creates — hours saved across the team, plus any revenue or retention gains.
- 3 The calculator converts time saved into money and compares it to the cost.
- 4 You get ROI %, net annual gain, and how many months until the tool pays for itself.
ROI % = (Annual benefit − Annual cost) ÷ Annual cost × 100, where Annual benefit = (Hours saved × 12 × Employees × Hourly cost) + Other gains.
Worked example
A 40-person operations team adopts a workflow tool costing 18,000 a year. Each person gets back about five hours a month, and the team also retires a 6,000-a-year reporting subscription it no longer needs.
- ·Annual software cost: 18,000
- ·Employees affected: 40
- ·Hours saved per employee per month: 5
- ·Fully loaded hourly cost: 32
- ·Other annual gain: 6,000
- 1. Hours recovered a year = 5 × 12 × 40 = 2,400 hours
- 2. Value of that time = 2,400 × 32 = 76,800
- 3. Total annual benefit = 76,800 + 6,000 = 82,800
- 4. Net gain = 82,800 − 18,000 = 64,800
- 5. ROI = 64,800 ÷ 18,000 = 360%
- 6. Payback = 18,000 ÷ (82,800 ÷ 12) = 2.6 months
ROI 360%, net gain 64,800 a year, payback in 2.6 months.
The number that matters here is not the 360% — it is the 2,400 hours. ROI this high is entirely a claim about whether recovered time turns into work that is actually worth 32 an hour. If the team simply absorbs the slack, the benefit is real for the people doing the job but never reaches the accounts. Treat the payback figure as the honest one: even if only a third of the time converts, the tool still pays for itself inside eight months.
Frequently asked questions
What is a good ROI for SaaS software?
Most teams target an ROI above 100% within the first year, meaning the tool returns more than it costs. Anything with a payback period under 12 months is generally considered a strong investment.
How do you calculate ROI on software?
Subtract the annual software cost from the annual benefit it creates (time saved valued in money, plus revenue or churn gains), divide by the cost, and multiply by 100 to get a percentage.
What is payback period?
The payback period is how long it takes for the cumulative benefit to equal what you spent. A 6-month payback means the tool covers its own cost in half a year.
Should I include implementation and training costs?
Yes. For an accurate picture, include one-time costs like setup, migration and training in the total cost — or use our TCO calculator for the full lifetime cost.
How do I value time saved?
Multiply hours saved per employee per month by 12, by the number of employees, and by their fully-loaded hourly cost (salary plus benefits and overhead).
What counts as a benefit in a software ROI calculation?
Three things, in descending order of reliability. Cash you stop spending — a licence retired, a contractor no longer needed — is certain. Cost you avoid, such as penalties or rework, is likely but needs an estimate. Time saved is the largest number and the least certain, because it only becomes money if the hours are redeployed into something valuable. Keep them separate so a reviewer can discount the soft part without redoing the whole sum.
Should I use salary or fully loaded cost for the hourly rate?
Fully loaded — salary plus employer taxes, benefits, equipment and a share of overhead. It is typically 1.25 to 1.4 times base salary. Using bare salary understates the value of recovered time by a quarter or more, which makes a genuinely good investment look marginal.
Why is payback period more useful than ROI to a finance team?
ROI compresses a whole year into one percentage and hides when the money actually arrives. Payback answers the question a CFO asks first: how long is our money at risk? A tool with 200% ROI and a two-month payback is a far easier approval than one with 400% ROI that takes nine months to turn, because the second carries three more quarters of execution risk.
What ROI is high enough to approve a purchase?
There is no universal threshold, and treating a big percentage as self-justifying is how bad purchases get approved. What matters is the comparison: the return has to beat the next best use of the same money, and the payback has to be short enough that the assumptions behind it are still true when it lands. A modest, well-evidenced return usually survives scrutiny better than a spectacular one built on estimated time savings.
