Net Worth Tracker vs Spreadsheet: Which Should You Use?
Spreadsheets are free and flexible, but they go stale. Here is an honest comparison of tracking your net worth in a spreadsheet versus a dedicated tracker.
For years, the spreadsheet was the only free way to track your net worth. It still works, and millions of people rely on one. But a dedicated net worth tracker now does the same job with far less upkeep — and many are also free. This is an honest comparison so you can pick the right tool for how you actually behave, not how you wish you behaved.
The Case for a Spreadsheet
Spreadsheets have real strengths:
- Total flexibility. You can model anything — custom categories, formulas, projections, scenarios.
- Free and universal. Google Sheets and Excel are everywhere, and you fully own the file.
- No dependencies. Nothing can shut down or change pricing on you.
For someone who enjoys building systems and only checks occasionally, a well-made spreadsheet is genuinely good.
The Hidden Cost of a Spreadsheet
The problem is not capability — it is maintenance. A net worth spreadsheet is only as accurate as the last time you manually updated every value. And asset values never stop moving:
- Crypto prices change every second.
- Stocks move all day, every trading day.
- Gold and silver shift daily.
So your spreadsheet is correct the moment you finish updating it and slowly drifts out of date every minute after. Keeping it accurate means manually re-entering dozens of prices on every check — which is exactly why most net-worth spreadsheets are abandoned within a few months. The flexibility is real, but so is the friction.
There are formula tricks to pull live prices (GOOGLEFINANCE, third-party add-ons), but they are fiddly, often break, rarely cover crypto and metals well, and require ongoing upkeep of their own.
What a Dedicated Tracker Does Differently
A net worth tracker automates the part that makes spreadsheets fail: live valuation. You enter each holding once, and the tool keeps its value current automatically. The trade-off is less open-ended flexibility — you work within the tool's structure rather than a blank grid.
A good tracker also adds things a spreadsheet cannot easily do: allocation visualisations, performance over time, and analysis like risk and diversification scoring.
A Free Tracker That Keeps Spreadsheet-Style Ownership
The usual objection to trackers is that they cost money or require an account. WalletLens avoids both: it is free, needs no account, and — like a spreadsheet file — stores everything locally on your device rather than on a company's servers. You get automatic live pricing across crypto, stocks, gold, cash and FX, plus allocation and AI analysis, while keeping the privacy and ownership that make spreadsheets appealing. You can import an existing spreadsheet via CSV to get started, and export a backup code at any time, so you are never locked in.
Which Should You Choose?
- Choose a spreadsheet if you value total customisation, enjoy maintaining it, hold only a few slow-moving assets, and check infrequently.
- Choose a dedicated tracker if you hold assets whose prices move constantly (crypto, stocks, metals), want an always-current number without manual updates, and value built-in allocation and analysis.
Many people end up using a free local-first tracker for the day-to-day live picture and a spreadsheet only for long-term projections or scenarios the tracker does not model.
> Educational note: Both approaches are informational tools, not financial advice. Whatever you choose, keep one durable backup so a lost file or cleared browser never erases your records.
Conclusion
A spreadsheet is free and infinitely flexible, but it goes stale the instant prices move and dies by manual upkeep. A dedicated tracker trades some flexibility for an always-accurate number and built-in analysis. The old reason to prefer a spreadsheet — privacy and ownership — no longer requires the trade-off, because a free, local-first tracker like WalletLens keeps your data on your device while updating values automatically. Pick the tool that matches how often you will actually maintain it; the best net worth tracker is the one you will still be using a year from now.
