Fixed vs variable expenses

Explore why fixed costs are easy — lock them in.

In this lesson

Fixed vs variable expenses is part of Income and Expenses. This preview shows how budgeting connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Today’s money mission

Imagine this situation: School bus fee: 3000 in local currency/month (same every month). Snack spending: varies 500 in local currency–2000 in local currency.

What you need to know

Fixed costs are easy — lock them in. Variable costs require active attention because they can creep up unnoticed.

Real-life example

Real-life money moment: Monthly income: 15000 in local currency. Fixed: school fees 4000 in local currency, transport 3000 in local currency. Variable: food 2000 in local currency–4000 in local currency, entertainment 500 in local currency–2000 in local currency.

Progress Penguin connection

Open your withdrawal history for the past 4 weeks. Which transactions appear at a similar amount every week? Those are your fixed expenses. Which amounts vary significantly? Those are your variable expenses. Knowing the difference is the first step to controlling both.
