How to build the budget and cash-flow slide

Start with after-tax income

The budget has to work on take-home pay, not gross salary. If take-home pay is provided, use it. If it is missing, state your assumption and be conservative.

Separate fixed, variable, and goal spending

VariableGroceries, gas, eating out, entertainmentOften funds the first round of recommendations.
GoalsEmergency fund, retirement, college, car replacementNeeds automatic transfers and clear targets.

Find the surplus

If the case does not list every expense, build a reasonable placeholder budget. Judges usually want to see that you noticed the missing information and made disciplined assumptions.

Use the budget to fund the plan

Every recommendation should name its funding source. A plan that requires $800 per month but only finds $150 of surplus is not credible.
