Forgotten Subscriptions Tracker ·

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

To hit $30k ARR you need 500 paying users at $5/mo - doable but Rocket Money is free, your bank probably already does this, and you'll burn $20k getting there; honest expected take-home year 1 is negative.

Market size (TAM)

$52.0M

~260M US adults × ~8% willing to pay for a dedicated sub-tracker (vs. free Rocket Money/bank-native tools) × $5/mo avg = ~$62M ceiling; discounted to $52M for realistic addressable slice

Year-1 ARR range

$6k - $160k

midpoint $32k

Gross margin

80%

Investment to production

$20k

Dev: $9k for Plaid/email-parsing integration, auth, billing, cancellation flows. Design: $3k for onboarding UX (trust is everything in finte

Probability of success

10%

P(reaching mid case in 12 months)

Expected take-home Y1

probability-weighted, after investment

Go-to-market motion

App store + SEO ('cancel forgotten subscriptions') → personal finance subreddits and YouTube/TikTok PF creators → freemium hook (show 3 subs free, pay to see all and 1-click cancel).

Key risks

Rocket Money (10M+ users, backed by Rocket Companies) and most major banks now offer this feature free - the core value prop is already commoditized before you ship
Plaid API costs ($0.30-$0.50/connected account/month) compress margins badly at the price points consumers tolerate; email-parsing alternative requires OAuth scraping that Gmail/Outlook actively fights
One-and-done churn: users link accounts, see subs, cancel the bad ones, then never open the app again - LTV collapses unless you build ongoing value (budgeting, alerts) which expands scope massively
