How This Net Worth Calculator Works
Net worth is calculated as assets minus debts. The value in this tool comes from organizing inputs by category and providing optional equity estimates for common items like a home or vehicle.
Quick Example (Illustrative Only)
Suppose a snapshot includes cash $6,500, investments $12,000, retirement $35,000, and a home valued at $320,000 with a mortgage balance of $250,000. Debts include credit cards $2,400 and student loans $18,000.
- Estimated home equity = 320,000 − 250,000 = $70,000
- Total assets = 6,500 + 12,000 + 35,000 + 70,000 = $123,500
- Total debts = 2,400 + 18,000 = $20,400
- Net worth = 123,500 − 20,400 = $103,100
Inputs Checklist (Common Mistakes)
- Double counting real estate: enter equity (value − loan) rather than the full property value if you also include the mortgage balance.
- Mixing values and balances: assets are values you own; debts are balances owed. Keep categories consistent.
- Using wildly different valuation sources: consistency matters more than precision for trend tracking.
- Ignoring smaller debts: small balances still count if the goal is accuracy.
What the Breakdown Shows
- Total assets: sum of all asset categories, plus optional estimated equity.
- Total debts: sum of all debt categories.
- Asset mix: a simple percentage breakdown by category.
- Debt mix: highlights where balances concentrate.

Limits & Assumptions
Results are estimates based solely on the values entered. Asset values, balances, rates, and assumptions can change over time. This calculator does not account for taxes, fees, penalties, timing differences, or provider-specific terms. Outputs are for informational comparison only and should not be relied upon as a decision-making basis.

What Counts as Net Worth (And What People Often Miss)
Net worth is a simple formula, but the quality of the number depends on how consistently you define what you include. Two people can use the same calculator and get very different results because they categorize items differently or mix “values” with “balances.” The goal of this page is to help you build a clean, repeatable snapshot so that changes over time are easier to interpret.
Assets vs. Debts: Keep the Definitions Clean
In basic personal accounting, assets are things you own that have value, and debts are amounts you owe. Where people get tripped up is combining full market values on the asset side with related loan balances on the debt side without being consistent.
- Values: what something may be worth today (cash balance, investment value, estimated resale value).
- Balances: what you still owe (credit card balance, loan principal, mortgage balance).
- Equity: the difference between a value and its related balance (estimated value − loan balance).
How to Handle Homes, Cars, and Other “Financed Assets”
When an item has both a market value and a related loan, many people prefer to track equity instead of tracking the full value on the asset side and the full balance on the debt side. Either approach can work as long as you’re consistent. The Breakdown mode supports equity by letting you enter a value and a related balance to produce an estimated equity figure.
Equity Consistency Checklist
- If you track equity for your home, avoid also listing the full home value as a separate asset.
- If you track a vehicle’s equity, avoid also listing the full vehicle value separately.
- If you track full market values, consider whether you’re also counting the related loan as a debt (so the math nets out).
Common Categories and Where They Usually Fit
Categories are just a way to keep your snapshot organized. If you use the same categories each time, you’ll usually get a cleaner trend line even if your numbers aren’t perfectly precise.
- Cash & savings: checking, savings, cash reserves.
- Investments: brokerage holdings and other taxable investments.
- Retirement accounts: 401(k), IRA, and similar accounts.
- Property/vehicle equity: estimated equity when a loan is involved.
- Other assets: items you choose to count for your own snapshot rules.
- Credit cards: outstanding revolving balances.
- Student/personal loans: installment balances owed.
- Other debts: any other balances you include consistently.
Why Net Worth Can Change Without You “Doing Anything”
A net worth change doesn’t always mean you saved more or spent less. Some components fluctuate on their own. That’s why snapshots are most useful when you compare them over the same time intervals using the same inputs and valuation approach.
- Market movement: investments can rise or fall independently of deposits.
- Debt amortization: some loan balances decline over time as payments are applied.
- Interest and fees: balances can grow if interest accrues or fees are added.
- Valuation changes: resale values can shift for homes and vehicles.
Snapshot vs. Breakdown vs. Tracker
This calculator offers three ways to work depending on how detailed you want your snapshot to be:
- Snapshot: fastest method when you already know your total assets and total debts.
- Breakdown: category-based entry with optional equity estimates for common financed items.
- Tracker: saves dated snapshots locally in your browser so you can compare changes over time on this device.
Privacy Note for Saved Snapshots
If you use Tracker mode, snapshots are stored only in your browser storage on this device. If you clear browser storage or use a different device, your saved entries may not be available. Export is provided so you can back up your saved snapshot file for personal reference.
Net Worth Calculator FAQ
Does this calculator store my data?
No. The calculator runs locally in your browser. If you choose to save snapshots, they are stored only in your browser on this device (localStorage) and are not transmitted to FinFormulas.
Is the result exact?
No. Results are estimates based on the numbers you enter. Real outcomes can differ due to valuation changes, timing, fees, taxes, interest, and provider pricing.
Should I include my home as an asset?
This is a personal accounting choice. Many people use equity (estimated value minus mortgage balance) rather than the full value to avoid double counting. This tool supports that approach via the equity estimate fields.
How often should I save a snapshot?
Many people update monthly or quarterly. Consistency helps you see trends over time even when values fluctuate.
Will this tell me what I should do with my money?
No. This tool provides arithmetic outputs from your inputs so you can track and compare snapshots. It does not provide individualized guidance or recommendations.
