The formula
Annualization makes mixed billing periods comparable. A monthly average is a budget allocation, not a prediction that the same amount will leave your account every month.
A worked example
A 12 monthly subscription costs 144 per modeled year. Adding a 120 annual service gives 264 annually, or 22 monthly on average.
How to interpret your result
Review individual annualized entries to see how smaller recurring charges accumulate.
Assumptions and limitations
Use the units, timing, and bounds stated beside the inputs. Example values are hypothetical; replace them with your own.
Weekly billing uses 52 payments. Price changes, promotions, fees, and taxes must be included by you.
