What moves the number most
The result responds to School Dinner Cost, Packed Lunch Cost, School Days Per Year, and Number of Children. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
The formula behind this
School days × children × cost difference. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Why run the calculation
Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.
What this doesn't capture
Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.
School lunch options produce annual cost based on the inputs provided.
