Back-to-School Budget Calculator
Sums back-to-school categories, adds a contingency percent, and compares the total with a budget cap.
Limitation: This calculator does not pull school-supply lists or district fees.
How to Build a Back-to-School Budget
Start from teacher lists and known fees, then add a contingency.
Enter supplies, clothing, fees/tuition, technology, transportation, and other.
Separate recurring tuition if needed
If tuition is already in a monthly education budget, keep only incremental seasonal fees here.
What the Back-to-School Result Means
The total includes contingency on the category subtotal. Remaining compares that total with your cap.
Back-to-School Examples

Entered school-season categories
Total with contingency
Subtotal 1,300 plus 130 contingency leaves 70 under a 1,500 cap.
Over-cap tech upgrade
Entered school-season categories
Total with contingency
Negative remaining means the plan exceeds the seasonal cap.
Buy from the list twice
Do a second pass after the first week of class when teachers add surprise materials.
