How the calculator decides what to flag

The calculator does not decide that a subscription is waste. It only marks a row for review when you label the tool as Rarely used and its importance as something other than Essential. That is deliberately conservative: a rarely used annual tax tool, compliance product or emergency backup can still be worth keeping.

Cost scenario: model keep/remove/change decisions with the AI Stack Cost Calculator.
Next step: plan upcoming decisions with the AI Subscription Renewal Planner, map shared jobs with the AI Tool Overlap Calculator, or use the AI Subscription Overlap Checker to investigate duplicated jobs, or work through the 10-minute audit checklist before cancelling anything.

AI subscription audit calculator FAQ

Does the calculator guess subscription prices?

No. Enter the amount you actually pay. Unknown prices stay unknown.

Does a review flag mean I should cancel a subscription?

No. It is only a prompt to investigate a subscription that you marked as rarely used and not essential.

Where is my calculator data stored?

Your entries are stored in your browser with local storage so you can return to them on the same device. No account is required.

Can I enter annual subscriptions?

Yes. Choose Annual and enter the real annual amount. The calculator converts it to a monthly equivalent for the total.

What should I do after I calculate my spend?

Review rarely used subscriptions first, then check whether their jobs are already covered elsewhere. Use the StackDiet audit to compare keep, cut, replace and overlap decisions in context.
