Family Net Worth Calculator

Your net worth is the single number that tells you where you stand financially — total assets minus total liabilities. This calculator breaks it down across home equity, retirement accounts, college savings, and every category of debt, then shows how your investable assets compare to Fidelity's retirement benchmarks for your age and income.

What your net worth number actually means

Net worth is the baseline — the scorecard of your financial life to date. But the number alone tells you less than its composition. Two families with identical $800,000 net worths are in very different situations if one has $750,000 in a paid-off house and $50,000 in liquid savings, while the other has $250,000 in equity and $550,000 in investable accounts.

For families in the $150,000–$500,000 income range, the relevant breakdown is:

• Home equity. Real wealth, but illiquid. Can be accessed via HELOC or refinance — but it can't pay college tuition or fund retirement directly without being sold or borrowed against.
• Investable assets. Retirement accounts + taxable brokerage + cash. This is the pool that will actually fund retirement and major goals. Fidelity's benchmarks (below) apply specifically to this number, not your total net worth.
• 529 accounts. Earmarked for education — counts toward college goals but not retirement. Including it in "investable assets" would overstate your retirement readiness.
• Other assets. Cars depreciate; business equity varies widely; life insurance cash value is accessible but usually slowly. These support the net worth number but shouldn't be counted on for retirement funding.

Fidelity retirement savings benchmarks — what they are and how to use them

Fidelity's widely-cited guidelines give a savings-multiple target by age. These apply to your retirement account balances (401k, IRA, Roth) — not total net worth or investable assets. They assume retirement at 67 and roughly 45% pre-retirement income replacement from savings (supplemented by Social Security).¹

Fidelity's five published benchmarks. The calculator interpolates linearly for ages between these points.

Limitations of the benchmark: The multipliers assume a single salary that remains constant. A dual-income household earning $280K combined — say $180K + $100K — has a more complex picture than a single earner at $280K. Also, these benchmarks assume roughly 45% income replacement from savings; if you plan to spend more aggressively in retirement (travel, second home, supporting adult children), you need more. A fee-only advisor can run the actual projections for your household's numbers and spending plan.

How to improve your net worth position

Net worth grows through two levers: increasing assets and reducing liabilities. For families in the $150K–$500K income range, the most efficient path runs through tax-advantaged accounts — every dollar you put into a 401(k) or Roth IRA reduces your tax bill and grows your asset base.

Priority order for accumulation

1. Capture full employer 401(k) match. This is an immediate 50–100% return on your contribution. No other move beats it.
2. Max HSA family contribution ($8,750 in 2026) if you have an HDHP. Triple tax advantage.
3. Max both Roth IRAs ($7,500/person in 2026, or use backdoor Roth above the phase-out). Tax-free growth forever.
4. Max 401(k) contributions ($24,500 in 2026, or $32,500 if 50+) — reduces current-year taxable income.
5. Fund 529 accounts to hit your college savings targets (see college cost calculator).
6. Taxable brokerage for any remaining surplus — no contribution limits, fully liquid.

Managing the liability side

Not all debt is equal. High-interest debt (credit cards, personal loans above 7–8%) should be paid off aggressively before investing beyond the 401(k) match. Low-rate debt (most mortgages, many student loans) is mathematically worth carrying while investing the difference at expected market returns. The mortgage payoff vs. investing calculator and student loan repayment guide can model this tradeoff for your specific rates.

Deferred tax on retirement accounts

The retirement account balance shown in this calculator — and in Fidelity's benchmarks — is a pre-tax number. When you withdraw from a traditional 401(k) or IRA in retirement, you'll owe income tax on the distributions. A $1,000,000 traditional 401(k) balance is worth roughly $700,000–$800,000 after tax, depending on your retirement income tax rate.

The after-tax value of your retirement accounts depends on:

• The mix of pre-tax vs. Roth balances (Roth withdrawals are tax-free)
• Your expected retirement income tax bracket
• Whether you'll be subject to RMDs (Required Minimum Distributions begin at age 73 for most; age 75 if born 1960 or later under SECURE 2.0)

A fee-only advisor can project the after-tax value and help you decide how much Roth conversion to do before Required Minimum Distributions begin — particularly in the years between retirement and Social Security claiming. See the Roth conversion strategy guide for the mechanics.
