What Is This?
The ADHD Tax Calculator quantifies the true annual financial cost of living with ADHD — covering late fees, impulse purchases, forgotten subscriptions, lost items, productivity loss, and missed income — giving you a clear number and actionable recommendations.
Why It Exists
The 'ADHD tax' is real, measurable, and consistently underestimated. Most people with ADHD know money leaks exist but have never added them up. Seeing the actual annual figure creates the clarity needed to prioritise system changes and stop the bleed.
Who It's For
- ▸Adults with ADHD who feel financially disorganised but can't pinpoint why
- ▸High earners who can't understand why money disappears despite good income
- ▸Anyone who wants to quantify the financial impact of executive dysfunction and make targeted improvements
How It Works
You input monthly amounts across six categories: late fees, impulse purchases, unused subscriptions, lost item replacement, estimated productivity loss percentage, and missed income opportunities. The calculator annualises every figure and returns your total ADHD Tax with a category breakdown.
You get:
- ▸Your total estimated annual ADHD Tax
- ▸A breakdown by category
- ▸Prioritised recommendations for where to plug the biggest leaks first
What Makes It Different
This isn't financial advice — it's financial visibility. All processing happens locally; no data is stored. The output is designed to motivate targeted action, not induce shame.
