Fixed vs variable expenses: distinguish them to manage better

When talking about budgets, we often mix everything together: rent, groceries, subscriptions, outings. Yet, not all expenses behave the same way. Distinguishing fixed from variable expenses is the first step to regaining control.

Fixed expenses: predictable and incompressible

Fixed expenses are those that come back every month for a stable amount:

  • Rent or mortgage
  • Insurance
  • Subscriptions (phone, internet, streaming)
  • Loan repayments

They often represent 50 to 60% of the budget. You can't easily reduce them, but you can anticipate them perfectly.

Variable expenses: this is where the margin is

Variable expenses change from month to month:

  • Groceries
  • Gas or transportation
  • Outings and leisure
  • One-off purchases (clothes, gifts)

This is where you have room to maneuver. It's also where budget overruns happen.

Exceptional expenses: the invisible trap

There's a third category often forgotten: exceptional expenses.

Car repairs, medical fees, vacations, taxes... These expenses don't come every month, but they represent a significant budget over the year. Not anticipating them guarantees a tough month when they arrive.
