Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Annual growth rate | Total net worth growth |
|---|---|---|
| $100k to $200k over 5yr | 14.87% | 100.00% |
| $50k to $250k over 10yr | 17.46% | 400.00% |
| $300k to $800k over 12yr | 8.52% | 166.67% |
| $25k to $40k over 3yr | 16.96% | 60.00% |
How This Calculator Works
Enter your net worth at the start and end of the period, with the years between them. The calculator finds the compound annual growth rate, the steady yearly pace that connects the two balances.
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
A net worth rising from $100,000 to $200,000 over 5 years is an annual growth rate of about 14.9%. Total growth is 100%, but the annual rate is what compares against past periods, market returns, and savings benchmarks.
Key Insight
Net worth growth bundles two engines — money you save and returns your existing portfolio earns. Early on it is mostly savings; later, compounding does more of the work. Tracking the split between the two clarifies whether to focus on the income or the investment side.
Net worth: the right calculation
Net worth = Total ASSETS minus Total LIABILITIES. Sounds simple, but the right inclusion list matters. ASSETS to include: cash and HYSA, brokerage and taxable investments, retirement accounts (401k, IRA, Roth IRA), home equity (current market value minus mortgage balance), other real estate (rental properties, land), business interests (private companies you own equity in), vehicles (titles), valuables (jewelry, art, collectibles — at FMV).
LIABILITIES to include: mortgage balance (matches the home asset side), auto loans, credit card balances, student loans, personal loans, HELOC balances, business debts (if you own a business directly), any unpaid taxes.
Items often forgotten: future Social Security benefits (NOT included — they're a future income stream, not a current asset), pension benefits earned but not yet collected (debatable — include present value if eligible, or just track when collecting), expected inheritances (NEVER include — too uncertain). Be conservative: include only assets you control and could theoretically convert to cash today.
Benchmarks: where you should be by age
Fidelity's age-based net worth benchmarks (oft-cited rough targets): age 30: 1× annual salary saved. Age 35: 2×. Age 40: 3×. Age 45: 4×. Age 50: 6×. Age 55: 7×. Age 60: 8×. Age 67: 10×. These are 'savings' targets (retirement + brokerage) not full net worth — many people also have home equity beyond.
Comparison to US median: by age 40, median US household net worth is ~$135,000 (per Federal Reserve Survey of Consumer Finances, SCF 2022). For top quintile (~top 20%): ~$430,000 by 40. The Fidelity '3× salary' benchmark at 40 ($75k salary → $225k saved) is moderate — achievable for disciplined savers, harder for lower incomes.
Don't anchor on US median if you're earlier-career. Median 35-44-year-old has $135k net worth but that includes home equity. The same age range's retirement accounts alone median: $30,000 — concerningly low. The Fidelity targets are realistic AIMS, not averages. If you're not there yet, focus on increasing savings rate (target 15-20% of gross income) rather than panic-comparing to medians.
Tracking growth: 10% annual is a great benchmark
Net worth GROWTH rate combines two things: (1) market returns on existing investments (averaging ~7-10% nominal long-term for diversified portfolio), and (2) new contributions from earnings ('savings rate'). The combination determines your annual net worth growth.
Worked example: $100k net worth at start of year. $80k salary, save 20% = $16k contributed. Mid-year average net worth: $108k. 7% return on that average: ~$7,560. End of year: $100k + $16k contributions + $7,560 growth = $123,560. Annual growth: 23.6%. As your net worth grows relative to contributions, the GROWTH RATE will SLOW toward the underlying return rate.
Long-term math: by year 20-30 of working, your accumulated portfolio dominates new contributions. A 50-year-old with $1M net worth contributing $20k/year has growth of: ~$70k (7% on $1M) + $20k = $90k = 9% growth. By 65 with $2M: ~$140k + $20k = $160k = 8% growth. As balance grows, growth rate naturally converges toward the underlying return rate (~7%).
Net worth benchmarks by age (Fidelity targets)
Suggested net worth at salary multiples by age. These are 'retirement savings' targets — home equity, college savings, etc. additional.
| Age | Salary multiple | On $50k salary | On $80k salary | On $150k salary |
|---|---|---|---|---|
| 30 | 1× | $50,000 | $80,000 | $150,000 |
| 35 | 2× | $100,000 | $160,000 | $300,000 |
| 40 | 3× | $150,000 | $240,000 | $450,000 |
| 50 | 6× | $300,000 | $480,000 | $900,000 |
| 60 | 8× | $400,000 | $640,000 | $1,200,000 |
| 67 (full SS age) | 10× | $500,000 | $800,000 | $1,500,000 |
These are GUIDELINES, not requirements. They assume the 4% safe withdrawal rule provides about 25-30% of pre-retirement income from savings (with Social Security covering the rest). Lower-savings retirees lean more on SS; higher-net-worth retirees retire on savings alone.
Frequently Asked Questions
What is a net worth growth rate?
It is the compound annual rate at which net worth has grown — the per-year pace that links the starting and ending balance.
Should I include home equity?
Net worth conventionally includes home equity. For a 'liquid' or 'investable' net worth, exclude it and rerun the figure — the two often grow at different rates.
Why use an annual rate?
Total growth depends on how long you measured. Annualizing it lets you compare against market returns, prior periods, and other households on equal footing.
What is a good growth rate?
It depends on stage and income. Early earners with low balances can post very high rates from saving alone; later, growth tends to converge toward market returns on the portfolio.
How is this different from investment return?
Investment return measures only what your portfolio earned. Net worth growth includes savings, debt paydown, and price changes in everything you own — savings often outweigh returns in the early years.

Methodology & Review
The growth rate is the compound annual rate between net worth at the start and end of the period. It is a net figure — savings plus investment returns minus debts paid down or taken on — and does not separate the contributing forces.
