Most solopreneurs subscribe to AI tools hoping they'll save time, but few actually measure the return. This calculator gives you a concrete answer in seconds.
The formula
Monthly savings = hours saved per week × 4.33 × your hourly rate. Subtract the subscription cost to get your net gain. Divide net gain by cost to get ROI as a percentage. Payback period tells you how many days of savings it takes to cover one month's subscription.
What counts as "hours saved"?
Count any task the tool handles faster than you would manually: writing drafts, editing video, generating code, scheduling meetings, designing graphics. Be conservative. If a tool cuts a 2-hour task down to 30 minutes, that's 1.5 hours saved per occurrence.
Choosing your hourly rate
If you bill clients by the hour, use your rate. If you're salaried, divide your annual compensation by 2,080 (40 hours × 52 weeks). Freelancers and founders should factor in what their time is worth when redirected toward revenue-generating work.
