The answer will change how you optimize.
People optimize the expenses they can see.
The real leverage is usually where they never look.
The Situation
Fixed expenses are set commitments: rent, loan payments, insurance premiums. Variable expenses flex month to month: groceries, dining, entertainment. Most budgeting advice focuses on cutting variable costs — but the largest opportunities are often in renegotiating fixed ones.
Cutting your daily coffee saves you $1,500 a year. Renegotiating your rent saves you $6,000. Both matter. The order matters more.
— Worthune Decision Framework
The Framework · Steps 1 & 2
Rent/mortgage, car payment, insurance, loan minimums, subscriptions, memberships. Calculate the total. This is your financial floor — the minimum your life costs each month.
Know your floorGroceries, dining, gas, entertainment, clothing, personal care. Use 90-day averages, not single months. Variable costs are deceptive in any one-month snapshot.
Use 90-day averagesThe Framework · Steps 3 & 4
Review every fixed cost annually: can insurance be re-quoted? Can subscriptions be downgraded or cancelled? Can service plans be renegotiated? Fixed savings compound monthly.
Audit annuallyWithin variable expenses, focus on the highest-spend categories first. A 20% reduction in a $600/month variable category saves more than eliminating a $20 subscription.
Target by sizeThe Framework · Steps 5 & 6
Not all fixed costs are bad — some buy time, convenience, or security. The question isn't 'can I cut this?' but 'does this cost justify its permanent claim on income?'
Justify each oneEvery 6 months, check for costs that have quietly increased: streaming services, software, insurance, gym memberships. Passive increases compound silently.
Review for creepAfter the Work
After mapping your fixed vs variable split:
Your fixed floor is manageable. Focus shifts to variable optimization.
Large fixed costs limit your ability to save or respond to income changes.
You have optimization available without changing your lifestyle.
Optimize the big fixed costs first. The daily habits second.
