Most people do not know exactly how much they spend each month. They know the big number — rent, mortgage — but overlook the dozens of small expenses that silently accumulate: subscriptions they no longer use, food deliveries, bank fees. Without that clear map, it is impossible to calculate your emergency fund, know how much you could invest, or understand why money disappears each month.
Expenses fall into two main types:
- Fixed expenses: They repeat identically every month. Rent, mortgage, insurance, subscriptions, loan instalments. They are easy to list — the hard part is remembering all of them.
- Variable expenses: They change from month to month. Food, transport, leisure, clothing, restaurants. These are the hardest to track because they involve many small transactions.
'Silent leaks': One of the most common findings is discovering active subscriptions for services you no longer use, recurring expenses that 'seemed small' and that silently add up to $55–$110 per month. Identifying those leaks is money recovered without reducing your quality of life.
Someone thinks they spend about $1,320 per month. On reviewing their statement they find: $11 for an app they no longer use, $15 for a gym they rarely go to, $39 in food deliveries, $13 for a duplicate subscription. Just those items: $78 per month — $937 per year that could go towards the emergency fund or investing.
