ADHD tax calculator: tally everyday extra costs

The "ADHD tax" is a popular name for the everyday extra costs that can come from forgetting, losing or rushing things. Think of a late fee, or a subscription you meant to cancel. It has nothing to do with income tax. Pick a month or a year, type what you think you spent, and see the total. Guesses are fine.

Anyone can use this. It doesn't check for ADHD or diagnose anything.

These amounts are for:

We'll multiply by 12 for a yearly figure.

  • Fees or interest from paying a bill after the due date. Example: a late fee on a card.

    Count interest only if it came from paying late.

  • Charges for something you meant to cancel or stopped using. Example: an app you haven't opened in months.

    Count only the months you didn't use it.

  • Buying something again because it went missing or broke. Example: a second phone charger or new keys.

    Count it even if the first one turned up later.

  • Paying more because something was left late. Example: overnight shipping or a pricier last-minute ticket.

    Count only the extra over the normal price.

  • Things bought in the moment that you wouldn't buy again. Example: a gadget you never used.

    Skip anything you're glad you got.

  • Things paid for ahead that went unused. Example: a class you signed up for and didn't attend.

    If you counted it under subscriptions, skip it here.

  • Fees for a missed or late-canceled appointment. Example: a no-show fee at the dentist.

    Count the fee only.

  • Money you could have gotten back before a deadline passed. Example: a return window that closed.

    Use your best guess of what you would have gotten back.

  • Other costs from something slipping through. Example: a parking ticket or a replacement ID card.

    Leave it blank if nothing comes to mind.

Type an amount in any box to see your total. Leave the rest blank.
