How to Calculate Your Net Worth at 30 (Free Spreadsheet Template)

Most people in their 30s have a rough idea of their salary and maybe what's in their checking account. Very few have sat down and calculated their actual net worth — the full picture of where they stand after accounting for every asset and every debt.

That number matters more than your income. Someone earning $150k a year with $200k in student debt, a car loan, and no savings can have a lower net worth than someone earning $60k who's been quietly investing for eight years. Income flows through you; net worth is what stays.

This guide walks you through the full calculation, gives you a free spreadsheet template to do it yourself, explains what the result means at your age, and shows you the levers to pull if you want to change it.

Why net worth beats every other financial metric

Income tells you how much is coming in. Your bank balance tells you how much you have right now. Net worth tells you how much you've actually kept — and how much of what you "own" you actually own versus what the bank owns.

Net worth also compounds as a motivator. Once you see the number, you want to watch it grow. It turns abstract financial goals ("save more money") into a single trackable number that moves visibly over time with the right habits.

Step 1 — List all your assets

An asset is anything you own that has monetary value. This sounds simple, but most people either miss things or overvalue things. Go through each category carefully.

Step 2 — List all your liabilities

A liability is anything you owe. This is where people often undercount — it's psychologically uncomfortable to add it all up, so they avoid it. Don't. The whole point of this exercise is to see reality clearly.

Step 3 — Calculate and interpret the number

Once you have both lists, the math is simple subtraction. Here's a worked example for a typical 30-year-old:

That's a positive net worth of $42,100. Is that good? Bad? Average? That depends — and we'll get to benchmarks in a moment. But the key thing is: now you know. This person earns their income, drives a car, carries student loans, and has been investing consistently. The number reflects all of that at once.

The free spreadsheet template (Google Sheets)

Rather than building this from scratch, use the template below. It's a Google Sheets file with all asset and liability categories pre-filled, automatic totals, and a simple chart that tracks your net worth over time as you update it monthly.

Build it yourself in 5 minutes

If you prefer Excel or want to build from scratch, here's the structure:

COLUMN A          | COLUMN B
------------------|-----------
ASSETS            |
Checking          | [your value]
Savings           | [your value]
Roth IRA          | [your value]
401(k)            | [your value]
Brokerage         | [your value]
Home value        | [your value]
Car (KBB)         | [your value]
Other assets      | [your value]
TOTAL ASSETS      | =SUM(B2:B9)
                  |
LIABILITIES       |
Mortgage          | [your value]
Student loans     | [your value]
Auto loan         | [your value]
Credit cards      | [your value]
Personal loans    | [your value]
Other debt        | [your value]
TOTAL LIABILITIES | =SUM(B12:B17)
                  |
NET WORTH         | =B10-B18

What's a good net worth at 30?

The most cited benchmark comes from the book The Millionaire Next Door, which suggests your net worth should be roughly your age multiplied by your gross annual income divided by 10. At 30 earning $70k, that would be 30 × $70,000 / 10 = $210,000.

That sounds like a lot — and for most 30-year-olds, it is. But it's worth knowing that this formula was designed for people further into their careers. For someone who graduated with debt and has been working for 5–8 years, a more realistic range is:

What if your net worth is negative?

First: this is not unusual at 30. Student loans alone push millions of people into negative net worth territory for years after graduation. A negative number is information, not a verdict.

What matters is whether the trajectory is improving. Here's what to do:

How to grow your net worth in your 30s

Your 30s are the most important decade for building wealth. The decisions you make between 30 and 40 compound more powerfully than any other decade — there's enough time ahead for investments to grow, but also enough working years left to meaningfully increase income.

How often should you recalculate?

Once a month is the sweet spot for most people. It's frequent enough to see the trend clearly, but not so frequent that market fluctuations make it feel like a rollercoaster.

Pick a specific day — the first of the month is easy to remember — log into your accounts, update the spreadsheet, and you're done. The whole process takes about 10 minutes once the template is set up.
