How to Track Your Net Worth in 10 Minutes a Month

Net worth is everything you own minus everything you owe. It is the single number that tells you whether your finances are moving forward, because it captures saving, investing and paying down debt at once. A budget tells you where this month's money went; net worth tells you whether any of it stuck.

It is also the easiest financial habit to keep, because it only needs updating once a month.

What to count

Leave out furniture, clothes, electronics and anything else you would struggle to sell for a meaningful price. Including them inflates the figure without telling you anything useful.

Use resale value, not purchase price. A car bought for $30,000 is worth what a dealer would pay today. For a home, a sensible approach is the most recent estimate minus about 6–8% for selling costs.

Retirement accounts count at their balance, even though you would owe tax to withdraw them. Some people discount pre-tax accounts by their expected tax rate; that is more precise but not necessary, as long as you are consistent.

How often to update it

Monthly is right for most people. Weekly updates mostly show market noise, which is discouraging in a bad week and meaningless in a good one. Quarterly is fine if monthly feels like too much. Pick a fixed date, such as the first Sunday of the month, so it becomes routine.

What matters is the direction over a year, not any single reading. A figure that is negative but rising, which is normal for anyone with student loans, is a better sign than a positive one that is falling.

Three ways to track it

1. A spreadsheet. Free and fully under your control. List each account in a row, add a column for each month, and total the two sides. It takes about ten minutes a month once set up. Our net worth tracker template has the layout ready.

2. A free dashboard. Some brokerages and free apps will link your accounts and total them. They are good for investments but often weaker on loans and property.

3. A paid app. Apps such as Monarch link every account, update the figure daily and chart it over time. The advantage is that it never goes stale; the cost is a subscription.

Reading the number

Compare yourself with yourself. National averages are skewed upward by a small number of very wealthy households, and medians vary hugely by age. The Federal Reserve's Survey of Consumer Finances publishes both if you are curious, but your own trend line is more useful.

Watch what moved it. Each month, note whether the change came from saving, from paying down debt or from the market. The first two are under your control; the third is not, and it will reverse at some point.

Use it to set a target. The 25x rule turns annual spending into a net worth goal for financial independence, which gives the monthly number a destination.

Common mistakes

• Counting the home at its listing-site estimate. Those figures can be well off; use a conservative number.
• Forgetting small debts. A store card or a buy-now-pay-later balance is still debt.
• Updating too often. Daily checking turns a planning tool into a source of anxiety.
• Stopping when it falls. A market drop is exactly when the record is most useful, because it shows how much of your progress was saving rather than luck.

Common questions

What is a good net worth for my age?

There is no single right number, and averages are skewed by very wealthy households. A more useful test is whether your net worth is rising year over year.

Should I include my home in net worth?

Yes, at a conservative value minus likely selling costs, with the mortgage balance counted as a liability. Some people also track a second figure without the home to see their liquid position.

Can net worth be negative?

Yes, and it is common for people with student loans or early in their careers. What matters is that it is moving upward.

How often should I calculate my net worth?

Once a month on a fixed date suits most people. Quarterly also works. Weekly or daily updates mostly show market noise.
