Your monthly fees feel small, but where do they lead? Predict your total wealth drain over the next 1,000 days.
Visualize how small monthly expenses (like a $15 streaming sub) accumulate into thousands of dollars over a 3-year window.
Calculations are performed 100% in-browser. We don't use external APIs, bank links, or account registration.
Subscription services are designed to feel negligible on a monthly basis. A $15/month streaming service seems like a minor expense, but over 3 years, that single service costs you $540. When you stack 5 or 10 such services, you are looking at thousands of dollars in "invisible" wealth drain.
Subscription Simulator allows you to visualize the long-term impact of your current recurring costs. By projecting your expenses over a 36-month window, we help you make informed decisions about which "small" monthly fees are actually worth their long-term price tag.
We don't need your bank login. We don't store your data on a server. Every calculation, from addition to the Chart.js visualization, happens exclusively in your browser memory.
「サブスク将来支出シミュレーター」は、現在の月額課金が1年後、2年後、そして3年後に合計いくらになるのかを瞬時に計算します。
月々1,000円のサービスも、3年間使い続けると36,000円になります。複数のサブスクを契約している場合、その総額は驚くほど高額になることが珍しくありません。このツールを使って将来の支出を「見える化」し、本当に必要なサービスを厳選するきっかけにしてください。
