Enter your monthly subscriptions. See the true compounded cost over your career.
Are subscriptions really that costly? $46/mo sounds fine. But $46/mo × 35yr at 7% = $80,000+ in opportunity cost. The issue is subscriptions multiply silently — most households underestimate their total by 40%.
Methodology: Calculations use standard financial mathematics — Future Value of Annuity (FV = PMT × ((1+r)n − 1) / r), standard loan amortization for debt payoff, and the historical ~7% real S&P 500 return for opportunity-cost projections. All formulas are deterministic and identical to those used by Certified Financial Planners.
This calculator totals the annual cost of all your streaming subscriptions and shows the lifetime wealth equivalent of that combined spend — what it would be worth if invested over 10, 20, or 30 years. It's for anyone who has added subscriptions gradually and never totaled them up, or anyone wondering why their discretionary budget feels tighter than expected.
Monthly cost × 12 = annual subscription spend. That annual amount, treated as an ongoing investment at your chosen return rate, compounds into the future value using the annuity formula: FV = C × [(1+r)^n − 1] / r. A household paying $80/month for streaming ($960/year) at 7% over 20 years represents $49,800 in foregone investment wealth — for services they may use only occasionally.
Subscription creep is among the most common causes of budget leakage. A 2023 C+R Research study found the average American spends $219/month on subscriptions — while estimating they spend only $86/month. The $133 monthly underestimation gap means most people are carrying over $1,500/year in subscriptions they don't consciously track. Auditing subscriptions annually is one of the highest-ROI financial hygiene habits.
