Disposable income

GlossaryAugust 27, 20261 min

What is left once you have paid what you cannot not pay. It is the only figure that says whether a month is liveable — and it is on no statement.

Your account balance does not tell you whether the month will go well. It tells you how much is in there today, which is not the same thing: some of it is already spoken for. Disposable income is what remains once everything that leaves anyway has been taken out.

On $4,400 netAmount
Housing$1,250
Car loan and student loan$610
Subscriptions$96
Phone and internet$85
Insurance$95
Committed$2,136
Disposable$2,264 — 51.5%

Those $2,264 are not free money. Groceries and transport take about $780 of it: they are variable spending, not commitments, but they arrive every month. What is genuinely available is therefore $1,484, a third of the income.

Three figures, three different questions. $4,400 says what you earn. $2,264 says what you control. $1,484 says what you can decide on this month.

Worth keeping. A commitment is not a large expense, it is an expense you cannot skip this month. A $12 subscription is a commitment; a $600 plane ticket is not. The sorting is done on that question, not on the amount.

It is also why the housing ratio decides everything else: the higher housing climbs, the more your disposable income melts, and the more an unexpected bill becomes a debt. Our entry on the housing ratio puts a figure on what a point of mortgage rate is worth in month-end cash.

In Yoseri, the Budget page separates committed from variable on your real transactions, and shows what is left per day until the end of the month.
