How to track net worth monthly
One number, once a month, on the same day. After a year you have a chart that tells you more than any budget.
Why monthly
A budget shows where money went this month. Net worth shows whether all those months are adding up. Checking it once a year hides the pattern; checking it every day makes you react to market noise. Once a month is enough to see the trend and catch a problem early, such as a card balance that keeps growing.
The 15-minute routine
- Pick a fixed day: the 1st, or the day after your last paycheck of the month.
- Log in to each account and write down the balance: cash, investments, retirement, every loan and card.
- Update the home and car values only every three or six months; they do not need monthly precision.
- Look at the change from last month and write one line about why it moved.
That last line is the useful part. "Down 900: paid the car insurance and markets dipped" tells you the month was fine. "Down 900: card balance up again" tells you something needs to change.
What moves the number
- What you save: money moved to savings or investments.
- Debt paid down: every principal payment lowers liabilities.
- Market changes: investments and retirement accounts go up and down on their own.
- Depreciation: cars lose value every year.
- Big purchases: a new car on a loan can drop net worth even though you now own more.
Split the change into "what I did" (saving, paying debt) and "what the market did". The first part is the one to judge yourself on.
Example with made-up numbers
January 1: net worth 75,400
February 1: 76,350 (+950: saved 600, paid 450 of principal, investments −100)
March 1: 77,880 (+1,530: saved 600, principal 460, investments +470)
Reading the trend
After three months, look at the average monthly change. After twelve, you have a year-on-year number. Watch the debt-to-asset ratio too: if it falls month after month, you own more of what you have, even in a month when markets pulled the total down.
Setting a 2027 goal
Take your average monthly change from what you control (saving plus principal paid) and multiply by 12. That is a realistic starting goal for December 31, 2027. Raise it if a debt ends mid-year and that payment moves to savings. A goal tied to your own actions is more useful than a round number you saw online.
Common mistakes
- Changing how you value things month to month.
- Leaving out a debt because it feels small.
- Comparing yourself with averages by age instead of with your own past.
- Stopping after a bad month. A down month in the chart is normal; a gap in the chart is the real loss.

Frequently asked questions
How often should I track my net worth?
Once a month is a good rhythm: often enough to see the trend and catch problems, not so often that market noise drives decisions.
Why did my net worth go down when I saved money?
Markets may have fallen, a car lost value or you paid a large bill. Split the change into what you did (saving, debt paid) and what the market did.
What is a realistic net worth goal for a year?
Average your monthly saving plus debt principal paid over the last few months and multiply by 12. Adjust it when your income or debts change.
