Utilities inflation seasonal bills basics
Heating and cooling seasons change usage. Working from home can change daily patterns. Price plans or tariffs can shift. One-off adjustments or credits can distort a single month. Averaging smooths these swings.
Pick a sensible monthly average
A 3 month average is quick and recent. A 12 month average smooths seasonality. Choose the window that best reflects your current situation.
| Average type | When it helps | Tradeoff |
|---|---|---|
| 3 month | Recent view when habits changed recently. | Less season smoothing. |
| 12 month | Smooths winter/summer swings. | Less sensitive to very recent changes. |
Avoid mixed months and false signals
- Do not mix winter bills with summer bills without averaging.
- Watch for one time credits or catch up charges.
- Keep groceries and utilities separate.
- If you moved recently, use the most relevant months.
