About this tool
How to use it
- Review the default recurring services or add your own custom streaming, SaaS, fitness, and delivery subscriptions.
- Select the billing frequency (Monthly, Annual, or Weekly) and input the recurring charge amount.
- Flag rarely used or forgotten services to isolate your monthly 'Zombie Spend' candidate total.
- Adjust the expected annual investment return rate (5%, 7%, 10%) to model 5, 10, and 20-year compound wealth opportunity costs.
Why it matters
Micro-subscriptions silently drain thousands of dollars from household budgets over time due to status quo bias and automatic renewal billing. Converting low-usage monthly subscriptions into index fund investments generates substantial compound wealth.
When to use it
Conduct this audit quarterly, during annual financial reviews, or when evaluating new streaming services and software memberships.
Common questions
What is a zombie subscription?
A zombie subscription is an active recurring charge for a product or service that you rarely or never utilize, such as an unattended gym membership or duplicate cloud storage plan.
How is the 10-year opportunity cost calculated?
It uses the future value of a monthly annuity formula: FV = P * (((1 + r/12)^(12*t) - 1) / (r/12)), where P is your monthly subscription outlay, r is the annual compound return (e.g. 7%), and t is years.
Is annual billing always cheaper than monthly?
Most software and media platforms offer 15% to 20% discounts for paying annually upfront, but only commit if you are confident you will actively use the service for the full 12 months.
