Everything you owe: mortgage, loans and balances.

Annual Spending in Retirement Help

What you expect to spend per year once work is optional, in today's dollars.

This net worth & wealth calculator runs on the standard FIRE model: yearly spending divided by a safe withdrawal rate sets the target, and savings compound monthly at the return you enter.

Explanation

Your net position today, how leveraged it is, and how long it alone funds current spending.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Add up everything you own at current market value.

Assets = investments + cash + property + valuables
Total assets:$350,000
Result: $350,000 in assets
Step 2

Add up everything you owe, including the full mortgage balance.

Debts = mortgage + loans + balances
Total debts:$120,000
Result: $120,000 in debts
Step 3

Subtract debts from assets for net worth, then express it as ratios.

Net worth = assets − debts
Assets:$350,000
Debts:$120,000
Result: $230,000 net worth · 65.7% equity
Final Answer
$230,000

Annual Spending in Retirement:$60000

Calculation

1. Add up everything you own at current market value. → $350,000 in assets 2. Add up everything you owe, including the full mortgage balance. → $120,000 in debts 3. Subtract debts from assets for net worth, then express it as ratios. → $230,000 net worth · 65.7% equity

Result

Your Net Worth: $230,000

Interpretation

Your net position today, how leveraged it is, and how long it alone funds current spending.

Understanding Your Result

Your Result: Your Net Worth: $230,000

Typical range: Median US household net worth is roughly $200,000 — but the only comparison that matters is your own trajectory.

What This Means

Your net position today, how leveraged it is, and how long it alone funds current spending.

Why It Matters

Net worth $230,000 ($350,000 assets − $120,000 debts); 65.7% equity; 3 years 10 months of spending runway.

Professional Interpretation

Net worth $230,000 ($350,000 assets − $120,000 debts); 65.7% equity; 3 years 10 months of spending runway.

How this is calculated

Subtracts everything owed from everything owned for the single scoreboard figure, then expresses it as equity ratios and months of spending runway.

What drives the result

Compound growth means each year's gains earn their own gains the next year. Over a decade that curve looks gentle; over two or three it goes nearly vertical. That is why starting early beats investing more later, and why projections over 20+ years show growth overtaking contributions — the money starts working harder than you do.

Recommendations

  • •Recalculate quarterly — trends beat snapshots for motivation and planning.
  • •Grow the gap from both ends: every debt dollar repaid and every asset dollar added counts once.

Educational Content

Introduction

Wealth is what compounds when spending stays below income and the difference is invested. Net worth is the scoreboard, growth projections are the forecast, and goal timelines turn the forecast into a plan. This page connects all three with one consistent compounding model.

Concept Explanation

Compound growth means each year's gains earn their own gains the next year. Over a decade that curve looks gentle; over two or three it goes nearly vertical. That is why starting early beats investing more later, and why projections over 20+ years show growth overtaking contributions — the money starts working harder than you do.

Applications

▸Projecting savings and contributions decades into the future
▸Setting a wealth goal and solving for the monthly deposit that hits it
▸Tracking net worth as the single scoreboard of financial health
▸Comparing the first million (slow) with the second (fast)

Benefits

  • •Separates what you put in from what compounding created
  • •Turns deadlines into required monthly figures you can automate
  • •Makes net worth trends visible quarter after quarter
  • •Shows why time in the market beats timing the market

Limitations

  • •Fixed-return projections hide volatility — actual paths zigzag around the smooth curve
  • •Nominal figures overstate spending power; inflation takes roughly 2–3% a year
  • •Taxes and fees are not modelled unless you lower the return to allow for them
  • •Past market averages do not guarantee future returns

Best Practices

  • •Use 6–7% nominal (4–5% real) for stock-heavy projections, not recent bull-market returns
  • •Keep fund fees under 0.2% — a 1% fee erases roughly a quarter of long-run growth
  • •Recalculate net worth quarterly and projections yearly
  • •Increase contributions with every raise before lifestyle absorbs it

Common Misconceptions

Myth: The first million takes as long as the second
Truth: The first million is mostly contributions; the second is mostly compounding and usually arrives far faster.
Myth: You need high returns to build wealth
Truth: Consistent contributions at average returns beat erratic contributions chasing high returns.

Practical Tips

  • •Recalculate quarterly and chart the trend
  • •Grow the gap from both ends: assets up, debts down
  • •Value property conservatively — optimism here hides risk
  • •Separate FI portfolio from total net worth mentally

Common Mistakes

Counting gross assets only
Debts are real; net of them or the figure lies.
Using purchase prices
Assets count at today's market value, not what was paid.
Checking too often
Monthly wobbles obscure the yearly trend that matters.

Assumptions

This calculator makes the following assumptions to provide estimates:

Market values current: Assets reflect saleable value today, not purchase price.
All debts included: Mortgages, loans and balances are all counted.
Runway is illustrative: Spending runway assumes assets could actually fund spending.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Fixed-return projections hide volatility — actual paths zigzag around the smooth curve
Limitation: Nominal figures overstate spending power; inflation takes roughly 2–3% a year
Limitation: Taxes and fees are not modelled unless you lower the return to allow for them
Limitation: Past market averages do not guarantee future returns

Frequently Asked Questions

Answers to common questions about this calculator.

Should home equity count?
Yes for net worth, no for FI progress — it is wealth you live in, not wealth that pays bills.
How often should I calculate it?
Quarterly. Trends motivate; daily noise does not.
What is a good debt ratio?
Under 30% of assets is comfortable, 30–50% watchful, above 50% fragile.
Who uses the net worth calculator?
It is used by savers planning independence, by advisers checking a client's number before big decisions, and by anyone tracking progress toward work-optional living. It sits in the Net Worth & Wealth group of the FIRE & Financial Independence section of Atlascalcs.
How accurate is the net worth calculator?
Every figure follows directly from the inputs using standard compounding and withdrawal mathematics, so it is accurate to the quality of the values you enter. Markets are volatile and inflation varies, so treat the output as a living plan and re-run it yearly with fresh figures.

Should I use nominal or inflation-adjusted returns?
This calculator uses the nominal return you enter. For spending power, either enter a real return (nominal minus ~2–3% inflation) or read long-horizon totals as nominal dollars that will buy less than today.
Does this account for taxes and fees?
Not automatically — lower the expected return by roughly your fee drag plus the tax bite (often 0.5–1.5 points combined) to approximate after-tax, after-fee results.
How often should I revisit my net worth plan?
Yearly, and whenever income, spending or the timeline changes materially. The inputs move slowly but compounding means small updates compound too.
