Choose a spreadsheet if you want complete control over data, formulas, and scenarios. Choose Beacon if you want a simpler manual workflow that keeps the core FI inputs and projected date in one purpose-built view.
A spreadsheet can be a brilliant financial tool. It can also become a fragile project that needs regular repairs. The right choice is about the amount of flexibility you need and the amount of maintenance you want to own.

When a spreadsheet is the better fit
Spreadsheets are ideal for highly personal models. You can include tax rules, multiple properties, family cash flow, custom categories, a detailed investment ledger, or scenarios that no finance app anticipates. You also control the format, formulas, and where the file lives. Google Sheets, Excel, and similar tools can support collaboration, templates, calculations, and charts, but the capabilities depend on how you build the model.
The trade-off is responsibility. A wrong formula, a stale input, or a hidden copied cell can alter a forecast. Build checks into any spreadsheet: keep assumptions separate, show the date of each balance update, and test key formulas with simple examples.
When Beacon is the better fit
Beacon is for people who do not need an all-purpose workbook. It makes the key FI relationship explicit: current investable assets, savings, spending, expected return, and withdrawal rate determine the projected path. You update the figures manually and can see how changing an assumption affects the date.
That focus can reduce noise. It also avoids treating every balance-sheet item as retirement capital. Track total net worth elsewhere if useful, then use the investable assets that can support spending for the FI plan.
A practical way to choose
- Use a spreadsheet when a custom model is part of the value you want, not merely a means to get a number.
- Use Beacon when you want to spend less time maintaining formulas and more time reviewing the few inputs that shape your FI date.
- Use both when a detailed spreadsheet is your source of record and Beacon is your concise recurring dashboard.
