Subscription Price Change History
Keep a dated history of subscription prices. Record increases, free periods and unknown amounts, then see how they affect projected renewal charges.
How can I track subscription price increases?
Save each new price with the date it takes effect. The history compares consecutive recorded prices and calculates a percentage change when the earlier price is known and above zero. Calendar and savings projections use the price effective on each scheduled charge date. Correct earlier records or export a CSV without private notes.
