kardfolio vs Spreadsheets
Spreadsheets work, especially if you like control. Here is what to track, when Sheets is enough, and when reminders, ROI, Kai guidance, and maintenance make kardfolio worth considering.

Quick decision
Stay with Sheets if...
You enjoy maintaining formulas, only track a few cards, and already review your sheet every month.
Move to kardfolio if...
Credits are slipping, renewal math feels fuzzy, or Player 1 / Player 2 upkeep needs reminders and card-level ROI.
The honest truth: spreadsheets can be a great credit card benefit tracker. They are flexible, free, and easy to shape around your own rules. The hard part is not starting the sheet. It is keeping reset windows, usage amounts, annual fees, enrollment tasks, and renewal decisions current after the novelty wears off.
Why People Use Spreadsheets
Spreadsheets are the go-to tool for credit card enthusiasts, and for good reason. They offer advantages that no app can fully replicate:
- Complete customization and control: build exactly the tracking system you want with custom formulas, charts, and layouts
- Free: Google Sheets costs nothing and works across all devices
- No account creation needed: no email signup, no password, no personal data shared
- Track anything, not just card benefits: spending patterns, sign-up bonus timelines, 5/24 status, and more
- Household flexibility: add Player 1 / Player 2 ownership, custom renewal notes, and whatever edge cases your card setup needs
Spreadsheet Columns Worth Tracking
If you are staying in Sheets, make the sheet useful enough that future-you can make a renewal decision without reconstructing the year from memory. These columns cover the basics for premium card benefits and household setups:

The most important fields are usually the boring ones: reset cadence, period start, period end, enrollment needed, next action, and renewal date. Those are the fields that turn a list of perks into a system you can actually maintain.
What Spreadsheets Can't Do
The limitations of spreadsheets become clear when you have multiple premium cards with dozens of benefits across different reset schedules:
- Expiration alerts:this is the biggest gap. Spreadsheets can't send you a push notification when your monthly Uber credit is about to expire. You have to remember to check.
- Auto-calculate ROI against current annual fees: a spreadsheet can do the math, but you have to manually update fee amounts when issuers change them
- Mobile-friendly tracking on the go: editing a spreadsheet on your phone while standing in line at Saks is not a great experience
- Sync across devices seamlessly: Google Sheets syncs, but the mobile experience is clunky compared to a native app
- Update benefit details when issuers change terms: when Amex restructures Platinum benefits (which happens regularly), you have to manually update every affected row
- No guided migration to app-based tracking: your spreadsheet data may be portable, but you still need a clean way to move from rows and formulas into a dedicated workflow

Who Spreadsheets Are Best For
Power users who want total control over their tracking system. If you enjoy building formulas, want to track more than just card benefits (sign-up bonuses, 5/24 status, spending targets), and have the discipline to update your sheet consistently, a spreadsheet gives you flexibility that no app can match.
Who kardfolio Is Best For
Cardholders who want automated tracking without the maintenance overhead. If you carry 3+ premium cards, tend to forget monthly credits, and want expiration alerts delivered to your phone, kardfolio handles the tracking so you can focus on actually using your benefits. No bank login required, so your financial credentials stay private.
CSV import is the bridge, not the pitch. If your card list already lives in Google Sheets or Excel, import it to avoid starting over, then let kardfolio handle the reminders, benefit periods, and ROI view that are easy to neglect in a manual sheet.
