How to calculate your net worth: free balance-sheet template
A personal balance sheet is a dated snapshot of everything you own, everything you owe, and the difference between them—your net worth.
Worked example

Calculate your net worth
Use one currency and one valuation date. Enter debts as positive amounts. The example starts in euros; you can replace every amount with your own currency.
- Assets
- 380,000
- Debts
- 170,000
- Net worth
- 210,000
Amounts in your chosen currency. Recalculate after changing inputs. Values stay in this page’s memory and are not saved or sent to analytics.
The one formula you need
Net worth equals total assets minus total liabilities. Assets are things you own that have a measurable value. Liabilities are amounts you still owe.
Net worth = assets − liabilities
How to create a personal balance sheet
- 01
Choose one valuation date. Values move at different times, so record the date beside every amount. Consistency matters more than false precision.
- 02
List your assets. Include cash, bank accounts, investments, pensions, property, vehicles, business interests, crypto, and valuable possessions you would genuinely count in your wealth.
- 03
List your liabilities. Include mortgages, personal and vehicle loans, credit-card balances, taxes due, and other outstanding debts.
- 04
Use current values. For liquid investments, use the value on your chosen date. For property and other illiquid assets, record the estimate source and use a consistent method.
- 05
Convert currencies consistently. Pick a base currency and use exchange rates from the same date. Keep the original currency so the source amount is not lost.
- 06
Add and subtract. Total each side, subtract liabilities from assets, and save the dated result for future comparison.
Worked example
| Item | Type | Value |
|---|---|---|
| 01Cash and bank accounts | Asset | €15,000 |
| 02Investments and pension | Asset | €75,000 |
| 03Home | Asset | €280,000 |
| 04Vehicle | Asset | €10,000 |
| 05Mortgage | Liability | €160,000 |
| 06Other debt | Liability | €10,000 |
Result: €380,000 of assets minus €170,000 of liabilities gives a net worth of €210,000. The numbers are illustrative, not a recommendation about what anyone should own.
Common mistakes to avoid
- 01Counting an asset but forgetting the debt attached to it.
- 02Mixing purchase prices, tax values, and current estimates without recording the method.
- 03Using exchange rates from different dates in the same snapshot.
- 04Updating easy accounts while leaving property, pensions, or loans stale for years.
- 05Treating a short-term market move as proof that a long-term plan is working or failing.
Personal balance sheet FAQ
Is a personal balance sheet the same as a budget?
No. A budget follows income and spending over a period. A balance sheet shows assets, liabilities, and net worth on a particular date.
How often should I update it?
Monthly is useful for active tracking. Quarterly is often enough when most values change slowly. Use the same routine each time.
Should I include my home and pension?
Include them if they belong to you and you can make a reasonable estimate. Record the method and date, and include any related debt separately.
What if my net worth is negative?
The formula does not change. A negative result means liabilities currently exceed assets. A consistent history can still show whether the gap is narrowing.
How do I update my net worth each month?
Choose a monthly check-in date, update each asset and debt from a current source, and save a dated snapshot. Keep the same reporting currency and valuation method so you can explain what changed. A monthly routine is a starting point, not a requirement to revalue every possession every month.
- Preserve the previous snapshot. Duplicate your spreadsheet tab or save a dated copy before editing. In Wealth Watcher, record new dated values so the earlier check-in remains part of your history.
- Refresh assets and debts together. Use statements or balances from the same date where possible. Record an older source date when a fresh value is unavailable. Include newly acquired assets, sold items and any new or repaid debts.
- Review estimates without inventing precision. Keep the last supported home or collection estimate if there is no new evidence, and note when it was last checked. Use the home’s full estimated value and the outstanding mortgage separately. Do not subtract the mortgage from home equity a second time, or count both collection items and their total.
- Keep currency conversion consistent. Record each original balance, then compare totals in the same display currency. In a spreadsheet, record the date and source of conversion rates. See the multi-currency example.
- Reconcile the movement. Check deposits, withdrawals, debt repayments, valuation revisions and exchange-rate effects before interpreting the new total. Revisit which assets fund your goal if your plans or access have changed.
A second month for the four-entry example
| Entry | 31 August | 30 September | Effect on net worth |
|---|---|---|---|
| Cash | €15,000 | €15,500 | +€500 |
| Investments | €25,000 | €25,200 | +€200 |
| Collection | €9,000 | €9,000 | €0 |
| Loan owed | €12,000 | €11,700 | +€300 |
| Net worth | €37,000 | €38,000 | +€1,000 |
Here cash rose by €500 after all transactions, investments were revalued up by €200 with no contributions or withdrawals, and loan principal fell by €300. The collection estimate stayed unchanged. These movements explain the €1,000 increase; they do not establish a portfolio investment return.
Paying €300 of loan principal out of existing cash would reduce cash and debt equally, leaving net worth unchanged before interest or fees. Do not add a repayment to net worth while ignoring where the cash came from. The table already uses closing balances after payments.
Use the free balance-sheet CSV and the Google Sheets formula walkthrough to try it yourself. For individual possessions, follow the collection workflow. You provide the estimates; the app does not automatically appraise them.
