Should You Include Your 401(k) in Net Worth?

Your 401(k), traditional IRA, 403(b), and other tax-deferred retirement accounts are real assets that you legally own — even though you cannot easily access them before age 59½ without penalty, and even though you will owe income tax when you eventually withdraw. The question is not whether to include them in your net worth (yes, you should) but at what value.

This guide explains the two valid approaches, when each is more useful, and how to track them in the free net worth calculator.

The Two Valid Approaches

1. Full pre-tax value. List your 401(k) at its current statement balance. If your statement says $145,000, your net worth includes $145,000. This is the most common approach and what most personal finance writers recommend.

2. Tax-adjusted value. Estimate the future tax you will owe and subtract it. If you expect a 22% effective tax rate in retirement, a $145,000 traditional 401(k) is "really" worth $145,000 × 0.78 = $113,100. Add this lower number to your net worth instead.

Both are valid. The full pre-tax approach is simpler and matches industry convention. The tax-adjusted approach is more conservative and gives a more realistic picture of "how much will I actually have to spend."

Why Pre-Tax Is the Default Convention

Most financial advisors, accountants, and personal finance tools use the pre-tax value because:

• It matches what your statement shows
• It is easier to track over time without needing tax assumptions
• The future tax rate is genuinely unknown — it depends on tax law changes, your retirement income level, your state of residence, and your withdrawal strategy
• Roth conversions, qualified charitable distributions, and other strategies can reduce the effective tax dramatically — over-discounting now ignores those options

For most people, the pre-tax value is the right default. It is easy, conventional, and not meaningfully wrong as long as you understand it represents the gross value, not the spendable value.

When Tax-Adjusted Net Worth Is More Useful

For specific situations, the tax-adjusted view tells you something important the pre-tax view does not:

You are within 5 years of retirement. The future tax rate is no longer hypothetical — it is the rate you are about to actually pay. Subtracting your expected effective rate gives you the realistic "what I have to live on" number.

You are deciding between traditional and Roth contributions. Comparing $100,000 in a traditional 401(k) to $100,000 in a Roth IRA is misleading because they are not equivalent. The Roth is fully spendable; the traditional is spendable minus future taxes. Tax-adjusting the traditional for an apples-to-apples comparison.

You are doing a "real" retirement readiness calculation. The 4% rule applies to spendable money. Running it against pre-tax retirement balances overstates your sustainable income by 15-25%.

How to Track Both Numbers

Use the free net worth calculator to track the full pre-tax value as your baseline. This is your "official" net worth — the number you compare to benchmarks and track over time.

Once or twice a year, do a separate calculation:

1. List each tax-deferred account at its current value
2. Multiply by (1 minus your expected effective tax rate in retirement)
3. For Roth accounts, do not adjust — they are already after-tax
4. Add all the adjusted values plus your taxable accounts plus other assets minus liabilities

The result is your "tax-adjusted" or "spendable" net worth. It will be lower than your headline number, but it is the more realistic picture for retirement planning.

For your effective tax rate, a rough rule of thumb: if you expect $50,000-$100,000 of annual retirement income, use 12-18% federal effective rate. Above $100,000, use 18-24%. Add your state tax rate (0% for some states, 5-13% for others).

What About Roth Accounts?

Roth IRA and Roth 401(k) accounts are after-tax — you already paid the taxes, and qualified withdrawals are tax-free. Their statement balance is the "spendable" balance.

For pre-tax tracking, list them at their full balance. For tax-adjusted tracking, also list them at their full balance — no discount needed.

This is why Roth accounts are disproportionately valuable in retirement. A $500,000 Roth IRA is worth $500,000 of spending power. A $500,000 traditional IRA is worth roughly $390,000-$425,000 of spending power after taxes. The Roth has 15-20% more usable value.

Frequently Asked Questions

What if I cannot easily look up my 401(k) balance?

Most plan providers have a website or mobile app. If yours does not, your quarterly statement shows the balance — use the most recent one. For monthly net worth tracking, even an estimate based on your contribution rate plus market returns is fine.

Should I include employer match if it has not vested?

No. Unvested funds are not yet yours. Include only the vested portion. Most 401(k) statements show vested balance separately.

What about old 401(k)s from previous employers?

Include them at full balance. Many people forget about old 401(k)s — they are still your assets. If you cannot find them, search the National Registry of Unclaimed Retirement Benefits.
