Crypto portfolio spreadsheet vs app: which one to pick
The crypto portfolio spreadsheet vs app choice splits on arithmetic against speed. Google's own reference describes the GOOGLEFINANCE price attribute as delayed by up to 20 minutes and names no cryptocurrency ticker at all, so a sheet's crypto prices are something you build. An app produces a current total; a sheet keeps the history behind it.
Key takeaways
- A spreadsheet holds what a phone tracker does not: purchase price, fees, dated rows, arbitrary formulas and CSV export.
- Google's GOOGLEFINANCE documentation covers stocks, funds and currency pairs and names no cryptocurrency ticker, so crypto prices in a sheet come from an IMPORTDATA or Apps Script call you maintain yourself.
- CoinGecko's
/simple/priceendpoint accepts up to 515 coin IDs per request and can return a last-updated timestamp — the freshness check worth wiring in, so a frozen quote is visible rather than silent. - A portfolio sheet is a plaintext inventory of your net worth, and it usually exists in several copies. An app on one phone has a smaller blast radius, though Android Auto Backup can still copy app data to a Google account.
- Holdtotal is on the app side of that split: no cost basis field, no transaction log, no CSV export.
A sheet holds notes about why you bought something. An app holds one number and shows it on a home screen.
Most people who track holdings seriously end up with both, and the split is stable: the spreadsheet is the ledger and the app is the dashboard. This page compares the two on live prices, arithmetic, phone ergonomics and privacy, gives a four-column sheet layout worth copying, and says which failure mode belongs to each. It is information about record-keeping tools, not financial advice.
Where does a spreadsheet beat a portfolio app?
A spreadsheet wins wherever the calculation is yours rather than the developer's. Cost basis is the clearest case: an app that only knows current amounts cannot tell you what you paid, while a sheet with a purchase price column computes average cost in one formula. Four things a sheet does that a phone tracker generally does not:
- Cost basis and realized gains. Your own columns for purchase price, date and fees, and whatever averaging method you decide to use.
- Arbitrary arithmetic. Allocation percentages, a target weighting, what a position would be worth at a price you type in as a scenario.
- History that stays. A row per purchase, kept for years, with the exchange or wallet named in a column.
- Export. CSV goes into tax software, into another sheet, into anything.
The cost of that flexibility is maintenance. Every formula is yours to repair, and a portfolio sheet that nobody has opened since March is a stale document that still looks authoritative.
Where does the spreadsheet fall down?
Live prices are the weak point. Google's own reference for the GOOGLEFINANCE function describes the price attribute as a "Real-time price quote, delayed by up to 20 minutes", and the whole documented attribute list covers stocks, mutual funds and currency pairs — the page names no cryptocurrency ticker syntax at all (GOOGLEFINANCE). People do wire crypto prices into sheets anyway, usually with an IMPORTDATA or Apps Script call to a market data API, and that is a small piece of software you now maintain: an API that changes a field name breaks your total silently, and a sheet showing a wrong number looks exactly like a sheet showing a right one.
The second weakness is the phone. Opening a spreadsheet app, waiting for recalculation over a mobile connection and scrolling to the total row is a twenty-second operation you will not perform six times a day. The third is more serious and gets discussed least: a portfolio spreadsheet is a plaintext inventory of your net worth. Shared from a cloud account, mailed as an attachment, or synced to a laptop that other people use, it is a document that says exactly what you own and how much of it. An app that keeps holdings on the handset has a smaller blast radius, though not a zero one — on Android, Auto Backup can copy app data to the user's Google account unless backup is turned off (Back up user data with Auto Backup).
A minimal sheet layout you can copy
Four columns are enough for a working ledger. Add a fifth for cost basis when you want gains as well as value.
| Column | Example | What it holds |
|---|---|---|
| A — Coin | BTC | Ticker, one row per coin, not per transaction |
| B — Amount | 0.184 | The canonical quantity you hold everywhere |
| C — Unit price | 61,240 | Price in USD, typed or pulled from an API |
| D — Value | =B2*C2 | Amount times price |
The total is =SUM(D2:D50) in a cell above the table, not below it, so it stays visible when the list grows. If you track cost basis, add column E for what you paid per unit and column F as =(C2-E2)*B2 for the unrealized difference. Keep one row per coin and a separate tab for transactions; mixing the two is what turns a sheet into a puzzle after a year.
Prices are the only part that needs a decision. Typing them by hand once a week is defensible and takes four minutes. If you automate, the CoinGecko API's /simple/price endpoint accepts up to 515 coin IDs per request and offers include_last_updated_at and include_24hr_change parameters, which the documentation notes return null if the price is stale — a freshness check worth wiring into the sheet so a frozen quote is visible (Coin Price by IDs).
Which one should you actually use?
Pick by the job, not by preference:
| If you want | Use |
|---|---|
| A total in two seconds, on the home screen | An app |
| Cost basis, fees, realized gains | A spreadsheet |
| A record for a tax preparer | A spreadsheet, exported to CSV |
| To check a number without unlocking anything sensitive | An app |
| To model an allocation you are considering | A spreadsheet |
| Fewest copies of your holdings in existence | An app on one phone |
Holdtotal sits on the app side of that table and does not pretend otherwise: you type the amounts in by hand, the way the manual tracking guide describes, it prices them and shows the total in dollars or in bitcoin with the 24-hour change, and a resizable home screen widget shows the total without opening anything. It has no cost basis field, no transaction log and no CSV export. If those matter to you, the sheet is doing work the app is not built to do.
This comparison is about tracking what you already hold. It does not cover tax calculation methods, accounting software, or the question of which assets belong in a portfolio at all. On the data side, the trade-off between typing amounts in and letting an app read them from an address or an API key is set out in the comparison of address, exchange key and manual entry, and what an absent account does and does not protect is covered in what no sign-up actually means. The unit question — dollars or BTC — is worth a page of its own, and gets one.
FAQ
Can Google Sheets pull crypto prices automatically?
Not through GOOGLEFINANCE in a documented way: Google's reference page for the function lists attributes for stocks, mutual funds and currency pairs and names no cryptocurrency ticker. Sheets can still fetch prices with IMPORTDATA or an Apps Script call to a market data API such as CoinGecko's. That works, but it is code you maintain, and a broken call can leave a stale number on screen.
Is a spreadsheet safer than a crypto portfolio app?
Not automatically. A sheet stored in a cloud account, shared by link or mailed as an attachment is a plaintext list of your holdings sitting in several places at once. An app that stores amounts on the phone keeps fewer copies, though Android Auto Backup may copy app data to your Google account unless you switch backup off. Neither option is private by default; both depend on how you use them.
Do I need both a spreadsheet and an app?
Many people use one of each, and the division of labour is simple: the sheet is the permanent record with purchase prices and fees, the app is the number you glance at. If you only want a current total, an app alone is enough. If you need cost basis for a tax preparer, the sheet is not optional, because no manual tracker on a phone is keeping that history for you.
