5 Ways to Track Your Cost Per Nut (Ranked by Effort vs. Accuracy)

You've decided to track your Cost Per Nut (CPN). Good. The next question is how. There are five real options, and they trade off the same two variables: how much effort it takes, and how accurate the number ends up.

1. The notes app

The default. Open Apple Notes or Google Keep, type a date and a number. Free, instant, and forgotten by Sunday.

• Effort: low
• Accuracy: low
• Best for: seeing if you'll actually stick with tracking at all

2. A spreadsheet

A column for date, a column for spend, a column for nuts, a formula at the bottom. Flexible, ugly, and surprisingly satisfying for the first month.

• Effort: medium
• Accuracy: medium
• Best for: people who already live in Google Sheets

3. A general budget app

YNAB, Copilot, Monarch. They'll tell you what you spent on "Restaurants," but they don't know which dinner ended in a nut. You'll have to do the dividing yourself.

• Effort: medium
• Accuracy: medium
• Best for: people already running a strict budget

4. Bank statement export

The truthiest method. Download CSVs, tag every line, then divide. Brutally accurate, brutally tedious.

• Effort: high
• Accuracy: high
• Best for: one-off audits, not weekly tracking

5. nuttr (purpose-built)

A tracker designed only for CPN. One tap to log, automatic charts, weekly review prompts. The only option that matches "low effort" with "high accuracy."

• Effort: low
• Accuracy: high
• Best for: anyone who wants to actually see the number trend over time

Which should you pick?

If you're not sure you'll stick with it, start with the notes app for two weeks. If you want a real number with charts and minimal friction, skip ahead to nuttr. If you love spreadsheets, you already know what to do.
