Fixed and variable household expenses: a complete list
Fixed expenses repeat every month for a similar amount (rent, utilities, installments, subscriptions); variable ones change with what you do (groceries, going out, clothes). Separating them tells you what you need every month no matter what, and where there is room to save.

The list
| Fixed | Variable |
|---|---|
| Rent or mortgage | Groceries |
| Building fees | Going out and delivery |
| Power, gas, water | Clothes and shoes |
| Internet and phone | Transport and fuel |
| Health insurance | Gifts |
| School or tuition | Home repairs |
| Insurance | Pharmacy |
| Subscriptions | Trips |
| Card installments | Treats |
Why separate them
Fixed costs are your floor: what you need each month even if you stay home. They are the base for the emergency fund (3 to 6 months of fixed costs). Variable costs are where the room is, and where budgets per category help most.
Fixed costs can come down too
Review them once a year: a cheaper phone plan, a subscription you don’t use, a better insurance deal. You do it once and save every month.
