Fixed vs variable expenses: what is the difference?

Fixed expenses stay about the same every month. Variable expenses change from month to month. Knowing which is which helps you plan, because fixed costs can be planned exactly and variable costs need a target.

Fixed expenses

Examples include rent, home loan or car EMI, school fees, insurance premiums, internet and subscriptions. The amount is known in advance, so you can take it out of your salary first.

Variable expenses

Examples include groceries, fuel, eating out, medicines, clothes and travel. These change with the month. Set a monthly target for each one rather than an exact amount.

Why the split matters

When fixed costs are high, there is less room for variable spending and savings. Compare the two totals each month to see whether your plan still works.

  • Fixed: known and repeating each month
  • Variable: changes and needs a target
  • Plan fixed costs first
  • Review variable costs every month
