Budget monitoring

Making a budget is only half the job. The other half is checking, month after month, whether the household actually stuck to it. This checking is called budget monitoring.

It means writing down what was actually earned and spent, then comparing this to what the budget planned. The gap between the two — not the budget figure itself — is what tells you whether the plan is realistic and whether it is being followed.

Monitoring has to be done on a continuous basis, not once at year-end. The workbook suggests an end-of-month review as the minimum, with a mid-month review possible if expenses are being noted down regularly.

When actual spending keeps missing a budgeted figure, the workbook's guidance is not to ignore it: either the budget figure needs to be raised to match reality, or the household's behaviour needs to change to bring spending back in line. Left unmonitored, small month-to-month misses compound into a much larger shortfall in savings by year-end.

The Rao household in Chennai budgets Rs 4,000 a month for conveyance. After three months of monitoring, their actual average conveyance expense comes to Rs 6,000 — a consistent miss of Rs 2,000 every month, or Rs 24,000 over a year if left unchecked.

Monitoring catches this early. The Raos have two choices: raise the conveyance budget line to Rs 6,000 and cut Rs 2,000 from somewhere else, or change their mode of travel to bring the actual cost back toward Rs 4,000. Either way, monitoring is what surfaced the gap — without it, the Raos would have kept assuming they were saving Rs 2,000 a month that, in reality, was going to unbudgeted travel.

Chapter 3, section 3.5, 'Monitoring budgets and provision for savings', works through the conveyance example above and sets out a step-by-step approach — such as raising the savings rate by a set percentage, like 10%, and diverting lump-sum receipts straight to savings — for closing a persistent gap. Expect a question distinguishing budget preparation (section 3.2) from budget monitoring (section 3.5) as two separate steps of the same process.

• Monitoring is not the same activity as preparing a budget — a candidate who only recognises section 3.2 (preparation) will miss questions specifically on section 3.5 (monitoring).
• A budget that is never compared to actuals gives no useful signal — the workbook stresses that monitoring, not the budget document itself, is what enables corrective action.
• The end goal of monitoring is not just accuracy, but preserving the savings figure — a persistent overspend anywhere in the budget eats directly into the amount left over to invest.
