A fixed expense stays the same each month, while a variable expense changes depending on how much you use or spend.

Quick Scoop

What is a fixed expense?

A fixed expense is a cost that doesn’t change regularly over a set period, such as every month or every year.
It’s usually tied to a contract or an ongoing agreement, so you pay roughly the same amount each time.

  • Common fixed expenses:
    • Rent or mortgage payments
    • Car loan payment
    • Subscription services with a set fee (like a streaming service)
    • Insurance premiums (health, auto, renter’s)

Example of a fixed expense:

  • Your apartment rent is 1,200 each month and doesn’t change from month to month under your current lease.

What is a variable expense?

A variable expense is a cost that changes from period to period based on usage, behavior, or circumstances.
You still expect these expenses to show up, but the amount is not the same each time.

  • Common variable expenses:
    • Groceries
    • Electricity or water bill (based on how much you use)
    • Gas for your car
    • Eating out, entertainment, and shopping

Example of a variable expense:

  • Your grocery bill is 180 one month, 220 the next, and 150 after that, depending on what and how much you buy.

Easy way to remember

  • Fixed expense → “Same every time” (like your rent).
  • Variable expense → “Changes every time” (like your groceries or utility bill).

TL;DR:

  • Fixed expense = regular, predictable amount (example: monthly rent).
  • Variable expense = fluctuating amount (example: monthly groceries).
