A Free Net Worth Calculator That Runs on iPhone and Mac With No App

The App Store has dozens of net worth tracking apps. Most are free to download but charge $5-15/month for any useful feature, and almost all require linking your bank accounts to a third party. If you want to track your net worth on iPhone or Mac without those trade-offs, the simplest option is to skip the app store entirely and use a browser-based tool.

The free net worth calculator runs in Safari (or any browser) on iPhone, iPad, and Mac. No App Store. No Apple ID. No subscription. Add it to your home screen and it works like an app — including offline after the first load.

The 30-Second Setup

On iPhone:

1. Open Safari and visit the free net worth calculator.
2. Tap the share button (the box with the up arrow).
3. Tap "Add to Home Screen."
4. Confirm. The icon appears on your home screen like any other app.

On Mac:

1. Open Safari and visit the same URL.
2. From the Share menu, choose "Add to Dock."
3. The site becomes a standalone app in your Applications folder.

From now on, opening the icon launches the calculator like a native app. There is no install, no permissions request, no Apple ID prompt.

How It Saves Your Data

The calculator uses your browser's local storage to remember your assets, liabilities, and totals between sessions. This means:

• Your data is saved on your iPhone or Mac, not on any server
• It persists when you close the browser and reopen it later
• It is private — only accessible to the same browser on the same device
• Clearing your browser data also clears the saved net worth (so back it up if you care about historical data)

For users who want to track on multiple devices (iPhone + Mac), the simplest workflow is to manually re-enter the latest numbers on each device when you update. Or, copy your numbers to a notes app or password manager that syncs across devices.

Why "No App" Is the Better Default

App Store apps for net worth tracking have several downsides browser tools avoid:

Subscription pressure. Most net worth apps follow a freemium model — basic features free, real features behind a $5-15/month subscription. Browser tools are free forever.

Data sharing. Apps that link your bank accounts share your data with their backend. Even apps that promise "we never sell your data" still process and store it on their servers, where it is subject to subpoena, breach, or policy change. Browser tools that run locally have no server to send data to.

App abandonment. Net worth apps come and go. The popular Personal Capital iPhone app was rebranded to Empower. Mint shut down entirely. Apps you depend on can disappear with little notice. A browser tool with local storage works as long as the website exists, and you can save the data offline as a backup.

OS-specific lock-in. An iPhone app does not work on a Mac, an Android phone, or a Windows laptop. A browser tool works on all of them with the same URL and interface.

Working Offline

After loading the calculator once, you can use it offline. The first visit downloads the page (the JavaScript that runs the calculation lives entirely in your browser, not on a server you have to call). After that, you can launch the home screen icon, add or update entries, and see your totals — all with airplane mode on.

This is useful for travel, for users who do not always have internet, or for users who prefer to use the tool without their device pinging any server in the background.

When You Need More

The browser tool covers the net worth tracking case. For other features, you may want additional tools:

• Spending tracking by category: A real budgeting app like YNAB or Monarch is better.
• Investment performance analytics: Your brokerage's built-in tools or a free service like Morningstar.
• Bank account aggregation: Apps that connect to all your accounts (with the privacy trade-off).
• Bill reminders: Calendar app or a dedicated bill reminder app.

For just the net worth picture — your total wealth, your trajectory, your debt-to-asset ratio — the browser tool is the simplest and most private option for iPhone and Mac users.

Frequently Asked Questions

Will the data sync between my iPhone and Mac?

Not automatically. Browser local storage is per-device and per-browser. To use both devices, manually re-enter the numbers on each, or save them to a synced notes app.

What if I get a new iPhone?

Your data lives in the old phone's browser storage. Before you switch, export your numbers (write them down or save to a note that syncs via iCloud), then re-enter on the new phone after setup.

Does it work on iPad?

Yes. Same URL, same setup. Add to home screen from Safari and it works as a standalone app on iPad.
