Liability

A liability is a claim someone else has on your money. It exists whether or not a payment is due this month, and it counts in full: the whole loan balance, not the installment; the whole card balance, not the minimum. A liability is measured by the balance it would take to make it go away today, however small the payment that keeps it quiet, which is why a $9,500 car loan with a $220 payment and a $9,500 savings balance cancel each other exactly on a net worth sheet. Only the principal part of a payment shrinks it; the interest part pays for another month of owing it.

In a sentence

• "The car loan is a liability of $9,500, even though only $220 of it is due this month."
• "A card you pay in full every month is still a liability on the day you measure, at whatever that day's balance is."
• "This month's electric bill is an expense. The mortgage is a liability."

How it works

One test decides whether something is a liability: someone could require you to pay it, and paying it would take a definite amount. That amount is the payoff balance today, not the payment, the original loan or the limit on a line of credit.

Left out: this month's bills that are not yet due, which are expenses rather than debts, and the rest of a lease, which is a commitment rather than a balance. An undrawn credit limit is not a liability either; only what has been borrowed is.

Balance after a payment = balance before + interest charged − payment

Every payment splits into the interest for the month and the principal that comes off the balance, and only the principal reduces the liability.

An example

Three debts over one month, with the interest rates as the example's assumptions.

The liability side of this household's net worth is $29,400, not the $490 that leaves checking each month. After one month it is $29,089: $311 of the $490 came off the balances and $179 paid for the month of owing them. The card barely moves, because two-thirds of its payment is interest, while the car loan, at a lower rate with a payment set to clear it, falls by $165. These are the three debts in the net worth example, where $53,400 of assets leave the household $24,000 ahead.

Why it matters

The liability side is where a household's real position hides. A checking balance that looks the same all year while a card balance grew is a falling net worth, and the payment that keeps the card current says nothing about the balance behind it. Reading every debt at its full balance turns "the payments are affordable" into "this is what I owe," the figure that decides whether the debts can be cleared and in what order. It also settles the direction of net worth: every dollar of principal paid is a dollar kept, the same as a dollar saved, so a month whose savings balance never moved can still have been a good one.

Liability versus expense

A liability is a balance that persists until it is paid; an expense is a cost that belongs to a month. The electric bill is an expense, counted in this month's cash flow and then gone; it becomes a liability only if it goes unpaid past its due date and turns into a balance owed. Paying a liability is only partly an expense. The interest part of a loan payment is spent, like rent; the principal part comes off the balance and stays in your net worth, the same as a deposit into savings. See How paying off debt raises your net worth.

Common questions

Is a mortgage a liability? Yes, at its remaining principal, on the liability side of net worth. The house it bought is an asset on the other side, at a realistic estimate of today's sale price, and the difference between the two is your home equity. A mortgage is usually the largest liability a household has and the slowest to move.

Is a credit card a liability if I pay it in full every month? Yes, at whatever the balance is on the day you measure. Paying in full keeps the balance from charging interest, but the purchases already made are owed until the payment clears, and leaving them out overstates net worth by that month's spending.

Is a car lease a liability? No. A lease is a commitment to keep paying for something you do not own, so it is neither an asset nor a liability; it is a bill in the budget, like rent. A 401(k) loan is a liability at its balance, and a HELOC is one at the amount drawn rather than its limit. See How to count a 401(k) loan, a HELOC, or a car lease in net worth.

Is a liability the same as debt? Nearly. Every debt is a liability, and in personal finance the two words are used interchangeably. Liability is the wider word: it also covers taxes owed and money owed to a person with no loan agreement.

Where it shows up in Zypper

Zypper keeps every liability at its balance and charts the total. Credit cards and loans, including mortgages and auto, student and personal loans, connect alongside checking and contribute their balances to the liability side of net worth, updating as payments post, so the balances falling by the principal each month show as a line rather than a set of statements; a loan that cannot be connected is added as a manual account whose balance you update when the statement arrives. Net worth is computed from every account, assets minus liabilities, and charted over time. See Net worth tracking and Supported account types, or get started with Zypper to see what you owe on one line.
