Most Americans have a rough sense of what they earn, but far fewer know what they're actually worth.
A net worth calculator can answer that question in about the time it takes to brew coffee, and the number it spits out often surprises people in both directions.
The math itself is simple: add up everything you own, then subtract everything you owe.
What trips people up is deciding what counts.
Your checking and savings accounts, retirement balances, brokerage accounts, and the market value of your car all belong on the asset side.
So does your home's estimated value if you own one.
On the debt side go your mortgage, car loan, student loans, credit card balances, and any personal loans.
One common mistake is leaving out the small stuff.
A $40,000 retirement account feels real, but so does the $2,300 sitting on a credit card you keep meaning to pay off.
Skip those balances and your result looks better than reality, which defeats the whole purpose.
Pull up every account statement in one sitting so nothing gets missed.
Another tip: use conservative estimates for things like your car and home.
Kelley Blue Book and sites like Zillow give quick ballpark figures, but remember that selling a house comes with fees and your car loses value every month.
If you're within a few thousand dollars, that's close enough for tracking purposes.
Net worth swings around with the stock market, so checking it daily can drive you crazy.
Most financial planners suggest recalculating every three to six months.
That's often enough to spot trends without overreacting to a bad week on Wall Street.
It's watching the direction it moves over a year or two.
A negative net worth at 29 isn't a crisis, especially if student loans are the main culprit.
A net worth that shrinks three calculations in a row, though, is a signal worth investigating.
Keep a running list of account logins somewhere secure so you're not hunting for passwords every time.
Track your credit card balances separately from month to month, since that's where small leaks tend to show up.
And if you're married or partnered, decide together whether you're calculating joint or separate numbers, because mixing the two produces confusing results.
Finally, don't compare your figure to the national averages you see online.
Those numbers include everyone from 22-year-olds with negative balances to retirees with paid-off homes.
Your comparison point should be your own number from six months ago. **The bottom line:** A net worth calculator is less about scoring yourself and more about seeing the full picture in one place.
Ten minutes twice a year is enough to catch problems early and confirm that your quiet, boring saving habits are actually working.
