AI Tool ROI Calculator
Determine if your AI tool subscription is worth it by calculating ROI based on time saved.
I subscribe to multiple AI tools and wanted to know if they actually save me money. This calculator forces you to put real numbers on the time saved versus the subscription cost — the answer is not always what you expect.
AI Tool ROI Calculator
- Click Use on any tool in the benchmark table to pre-fill its cost and typical time savings.
- Enter your hourly rate — what an hour of your time is worth to you or your employer.
- Adjust working days if needed, then click Calculate ROI.
These ranges are illustrative starting points, not verified per-tool benchmarks — actual time saved depends heavily on your role and how you use the tool. Click Use on a row to load them into the calculator below, then adjust to match your own experience.
| Tool | Monthly Cost (USD list) | Typical Time Saved | Best For | Load |
|---|---|---|---|---|
| ChatGPT Plus | $20/mo | 30–60 min/day | Writing, research, Q&A | |
| Claude Pro | $20/mo | 30–60 min/day | Long docs, analysis | |
| GitHub Copilot | $10/mo | 45–90 min/day | Developers | |
| Cursor Pro | $20/mo | 60–120 min/day | AI-first coding | |
| Microsoft Copilot 365 | $30/mo | 30–60 min/day | Office suite users | |
| Notion AI | $24/mo | 20–40 min/day | Docs & notes | |
| Grammarly Pro | $30/mo | 15–30 min/day | Writing & editing | |
| Perplexity Pro | $20/mo | 20–40 min/day | Research & search |
Time-saved ranges are illustrative, not independently verified for every tool — treat them as a starting point to adjust, not a guarantee. The two most solid published figures: OpenAI's own 2026 survey found workers save roughly 40–60 min/day on average with ChatGPT, and GitHub's 2022 controlled study found developers completed a coding task 55% faster with Copilot. Figures for the other tools come from vendor-published or anecdotal sources and are weaker evidence. Costs are standard monthly plan prices as of 2026, quoted in USD as most providers price internationally — UK customers typically pay the GBP equivalent, sometimes plus VAT.

The AI Tool ROI Calculator tells you whether your AI subscription is genuinely paying for itself. Enter the monthly subscription cost, the minutes it saves you on a working day, how many days a month you use it, and what an hour of your time is worth. You get the monthly value, the annual net gain, and the ROI as a percentage. Most people subscribe to AI tools on a hunch. This turns it into arithmetic. A tool saving 30 minutes on each of 22 working days is 11 hours a month, which at £25 an hour is £275 of time against a £20 subscription. The same sum runs the other way too: a £100 a month tool that saves ten minutes a day is buying you 3.7 hours, worth about £92, and is losing money. Use it when you are reviewing what you pay for, making the case for a tool at work, or choosing between a free tier and a paid one. It works the same way for a personal subscription and for a team rollout, where both the cost and the time saved scale with the number of seats.
Working Out Your AI Tool ROI Calculator
The AI Tool ROI Calculator is designed to give you an accurate answer in seconds. Follow these steps:
- 1Enter your monthly subscription cost. ChatGPT Plus is roughly £16 to £20 a month depending on whether the price you are shown includes VAT, and GitHub Copilot Pro is around £8 to £10.
- 2Enter the time saved on a typical working day, in minutes, then how many working days a month you actually use the tool. Twenty-two is a normal month. Track your real usage for a week first, and only count time genuinely saved rather than time the app was open.
- 3Enter your hourly rate. If you are salaried, divide your gross annual salary by 1,950 (37.5 hours a week over 52 weeks), or by 2,080 if you are on a 40-hour contract. If you are freelance, use your billing rate.
- 4Your monthly value, annual net gain and ROI percentage appear straight away, with a verdict on whether the subscription pays for itself.

The Maths Behind AI Tool ROI Calculator
Monthly ROI = (Hours Saved × Hourly Rate) − Monthly Cost | ROI % = (Net Return ÷ Cost) × 100
Formula: Monthly Value = (Minutes Saved Per Day ÷ 60) × Working Days × Hourly Rate Monthly Net = Monthly Value − Monthly Cost ROI % = (Monthly Net ÷ Monthly Cost) × 100 The value of the tool is the time it gives back, priced at your hourly rate. Subtract what you pay for it to get the net. Divide that by the cost and multiply by 100 for the percentage. Example: a £20 a month subscription saving 30 minutes a day across 22 working days, at £25 an hour. Hours saved = 30 ÷ 60 × 22 = 11 hours Monthly value = 11 × £25 = £275 Monthly net = £275 − £20 = £255 ROI = £255 ÷ £20 × 100 = 1,275% The soft number here is hours saved, and everything else depends on it. Time saved on a task is the difference between doing it with the tool and doing it without, not the time the tool was open. Most people get this wrong in one of two directions: counting every session as productive, or forgetting how long something used to take. Track a week honestly before you type a figure in, and if the answer comes out close to break-even, halve your estimate and see whether it survives. One thing the percentage does not capture: an hour saved is only worth your hourly rate if the hour goes somewhere useful. For a freelancer who bills it, that is real money. For a salaried employee it is real only if the time moves to work that matters rather than dissolving into the day.
Frequently Asked Questions
Is ChatGPT Plus worth it?
ChatGPT Plus costs UK customers somewhere around £16 to £20 a month, depending on whether the price you are quoted includes VAT. Take £20 and an hourly rate of £25: it needs to save about 48 minutes a month to break even, which is a shade over two minutes on each working day. Anyone using it regularly for writing, research, coding or summarising clears that without noticing. Someone who opens it a few times a month probably does not. Put your own usage in rather than trusting the headline, because the answer is entirely personal.
How do I calculate the ROI of an AI tool at work?
Work out the hours saved per month across everyone using it, multiply by the fully-loaded hourly cost of an employee, meaning salary plus employer National Insurance and pension divided by working hours, then subtract what the tool costs for the whole team. That last part is where these sums usually go wrong: most business tools are priced per seat, so ten people on a £25 seat is £250 a month, not £25. If each of those ten saves two hours a month and their loaded cost is £30 an hour, the value is 10 × 2 × £30 = £600, the net is £350, and the ROI is 140%. That is the version a finance team will accept.
What is a good ROI for a productivity tool?
Any positive figure means the tool earns more than it costs, but the sensible bar sits above zero because the hours-saved estimate is the least reliable input. A 100% ROI means you get back double what you pay. Individual AI subscriptions often produce very large ratios, in the hundreds of percent, simply because £20 is small next to an hour of professional time, so the number flatters the tool. The useful test is not the size of the percentage but whether it holds when you halve your time estimate. If it does not, keeping the subscription is a preference rather than a financial decision, which is fine as long as you know that is what you are doing.
What hourly rate should I use if I'm salaried?
Divide your gross annual salary by your contracted hours for the year. A UK full-time contract of 37.5 hours a week over 52 weeks is 1,950 hours, so a £35,000 salary works out at about £17.95 an hour. Use 2,080 hours instead if you are on a 40-hour week. If you want the figure your employer sees rather than the one you see, use total employment cost, salary plus employer National Insurance and pension contributions, over the same hours. Freelancers should use their billing rate, which reflects what the market pays for the time rather than what it costs.
