This tool models the schedule and price you enter. The live amount spreads each subscription period's price across that period for visualization. Actual provider charges, refunds, taxes, trials, and renewal rules may differ.
The counter uses your device's local time, so daylight-saving changes may alter clock-hour rates. No currency conversion occurs.
How does the subscription cost live counter work?
Current-period allocation equals period price multiplied by elapsed period time divided by total period time. Lifetime allocation adds completed historical period prices, the current fractional price, and any one-time fee.
Why are scheduled charges and allocated cost different?
Start-of-period timing includes the current period's full price immediately. End-of-period timing waits until its boundary. The allocation model spreads the price gradually; neither value confirms bank transactions.
Is every four weeks the same as monthly?
No. Four weeks is always 28 calendar days. Monthly recurrence advances from the original anchor date and clamps independently in shorter months.
How are price changes handled?
A change applies to the first billing period starting on or after its effective date. An active period is never split between prices.
