Up to three subscriptions, your monthly total and your yearly total, in English and in euros. Everything is calculated in your browser and no account is needed.
Unlimited subscriptions, all seven language versions and six currencies, the full five-year projection with an adjustable inflation rate, PDF and CSV export, and saved history synced to your account.
Translations and multi-currency totals take ongoing work to keep accurate. Keeping them in Pro lets us offer a genuinely useful free plan without ads, tracking or an account.
Yes. On the free plan your subscriptions stay in your own browser and are never sent anywhere. With Pro they are stored in your account so you can reach them from other devices, and only you can read them.
No. Open the page, enter your subscriptions and the totals appear immediately. An account is only needed for Pro features such as saved history.
Yes, at any time — your existing rows carry straight over. Pro is billed monthly or yearly through Stripe and can be cancelled whenever you like; access runs to the end of the paid period.
