How the Capital Gains Calculator template works

Simple short-term vs long-term gains tax estimate for a single sale. Open the spreadsheet, enter your own numbers, and let the formulas do the math.

When this template helps

01

You are deciding between two financial options and need a quick number.

02

You want to see how changing one input (rate, years, amount) shifts the result.

03

You want a calculation you can save and revisit, not a one-shot web form.

04

You want to tweak the math - this is a spreadsheet, not a black box.

Tips to get the most out of it

  • Keep the column labels simple - the formulas work best when categories are consistent month to month.
  • Plan the timing of sales regularly - once a week is a good rhythm for most people.

Common mistakes to avoid

  • Treating the result as a decision rather than an input. Calculators answer "what if" - the final call is yours.
  • Mixing up annual and monthly rates. If a formula uses a monthly rate, divide the annual by 12 before entering.
  • Ignoring taxes, fees, or assumptions. A result is only as good as the inputs you feed it.

Frequently Asked Questions

What is the difference between Free, Essentials, and Ultimate?

Free is a single-sheet starter template (sample data + How to Use guide). Essentials ($12) adds a dashboard, charts, expanded categories, and pre-filled subcategories. Ultimate (when available) adds multi-entity tracking, scenario analysis, and power-user reporting across 6-7 interconnected sheets.

Should I upgrade to Essentials?

Upgrade to Essentials if you want a dashboard with charts, more categories, larger capacity, and a more polished spreadsheet for ongoing use. The Free version is a good fit for one-off planning or trying out the layout.

Is Essentials worth $12?

Essentials is a one-time $12 purchase with no subscription. It typically adds a full dashboard, 30-50% more categories or rows than the Free version, and richer formulas. Most buyers upgrade after using the Free version for a few weeks and hitting its limits.

What is included in the free version?

The free Capital Gains Calculator is a single-sheet template with sample data and a "How to Use" guide. It covers the essentials. The Essentials version ($12) adds a dashboard, larger capacity, and extended categories; Ultimate (when available) adds multi-entity tracking and ultimate-grade reporting.

Which inputs should I edit?

Only the cells marked as inputs at the top. The rest are formula-driven outputs that update automatically when inputs change.

Can I save scenarios?

Save multiple copies of the file for different scenarios, or upgrade to Essentials/Ultimate for side-by-side scenario comparison in one workbook.

Is the file safe to download?

Yes. No macros, no sign-up, no tracking. The file is a plain .xlsx that opens directly in Excel, Google Sheets, or LibreOffice Calc.

How do I open this in Google Sheets?
