Bill gets paid for the first time on the last day of June. He has spent the whole of June the way most people spend the weeks before their first salary: without a plan, with a general sense that 900 euro on its way is enough for anything reasonable.
The evening the salary lands, he checks his account. He expected to have spent most of it. He has 495 euro left from the month, on top of what was already there.
He is surprised. Not because 495 is a large number, but because he had no target and still ended up with a surplus. He did not budget. He did not track. He just lived, and the structure of his situation, no rent, no mortgage, meals at home, did the work for him.
Budget variance analysis measures the difference between what was planned and what actually happened. A positive variance means reality was better than the plan. A negative variance means it was worse. Bill had no plan, which means his variance is unmeasured, and an unmeasured variance is not a success. It is a gap in the system.
He got lucky this month. His costs were low because his life is simple. The 495 surplus is real, but it is not the result of a decision. It is the result of a situation. Situations change. Decisions compound.
The ledger records the surplus. It does not record the luck.
The tip
A surplus without a plan is not evidence that the plan is working. It is evidence that you have not written one yet.
