Cash flow and net worth answer different questions
Cash flow says how much room this month leaves. Net worth says where you stand overall. A plan needs both.
All tracks and lessons
Know where you stand before you plan
Income, spending, what you own and what you owe — the four numbers every plan starts from.
In this lesson you will
- List income, spending, assets and debts in one place
- Calculate monthly cash flow and net worth
- Spot which debt costs the most from its APR
Most money advice starts with what to do next. That only works once you know where you are. Taking stock is a snapshot, not a judgement: four lists, made from numbers you can look up, that together show how much room each month leaves and where you stand overall.
The four lists
- Income: take-home pay from every regular source, after tax and deductions.
- Spending: one full month of what actually went out, from receipts, orders and bills.
- What you own: checking, savings, retirement and investment balances, plus major assets at a realistic value.
- What you owe: every card and loan, with its balance, interest rate (APR), minimum payment and due date.
Two numbers come out of it
Monthly cash flow is income minus spending. It tells you how much room the month leaves, and it is what a budget plans. Net worth is what you own minus what you owe. It tells you where you stand overall, and it is what goals and debt payoff move over time.
A negative net worth early on is common. Student loans and car loans often outweigh savings for years. The useful question is not whether the number is good, but which direction it is moving.
Why the APR belongs on the list
Two debts with the same balance can cost very different amounts. A $3,000 card balance at 24% costs about $60 a month in interest; a $3,000 loan at 6% costs about $15. Writing the rate next to every balance shows which debt is actually expensive, which is the first decision in any payoff plan.
Make it a habit, not a project
Write the figures down with the date, then repeat the snapshot every three to six months. Comparing two snapshots shows progress that a single month never will: debt shrinking, savings growing, spending settling into a pattern you chose.

Three ideas to keep
Direction beats the starting value
A net worth of −$250 that was −$2,000 six months ago is real progress. Compare snapshots, not yourself to others.
The rate is part of the balance
Interest per month is roughly balance × APR ÷ 12. Writing it down shows which debt is expensive to keep.
Do it in 5 steps
Gather take-home pay
Use a typical month after tax, including side income and benefits.
Capture one month of spending
Scan receipts and forward email orders so the month is complete.
List balances on one date
Every account you own and every debt you owe, with APR, minimum and due date.
Calculate and date it
Own minus owe, income minus spending. Write the date beside both numbers.
Book the next snapshot
Put a reminder three to six months out and compare.
A first snapshot: slightly negative, and a clear starting point
An illustrative early-career picture. Savings are growing, but loans still outweigh them.
| Item | Own or owe | Amount |
|---|---|---|
| Checking | Own | $1,850 |
| Savings | Own | $2,400 |
| Retirement account | Own | $6,500 |
| Credit card (24% APR) | Owe | −$3,000 |
| Car loan (6% APR) | Owe | −$8,000 |
| Net worth | −$250 |
$10,750 owned minus $11,000 owed. The card is the smaller debt but costs about $60 a month in interest, against about $40 for the car loan — so it is the first target.
Where this usually goes wrong
- Using gross salary instead of take-home pay
- Valuing a car or home at what you paid rather than what it would sell for
- Leaving out small debts such as store cards or buy-now-pay-later
Write down every debt you have with its APR. Multiply each balance by its APR and divide by 12. Circle the largest number — that is your most expensive debt.

Puzzle
You own $900 checking, $3,100 savings and a car worth $7,000. You owe $2,500 on a card and $6,000 on the car loan. What is your net worth?
Show the answer
$2,500
Owned: $900 + $3,100 + $7,000 = $11,000. Owed: $2,500 + $6,000 = $8,500. $11,000 − $8,500 = $2,500.
