YNAB Partner Split

About

Split shared transactions in YNAB in seconds.
If you regularly split expenses with a partner, this extension removes the manual work of editing each transaction and doing the math. Select transactions or flag them as you go, and automatically split them 50/50 between your category and a partner reimbursement category—keeping your budget accurate with far less effort.

Features
1. Split selected transactions in bulk
Select one or more transactions in YNAB, choose a category, and instantly split them 50/50 between your category and your partner reimbursement category.

2. Batch process using flags
Flag shared transactions as you go, then run “Split by flag” to process them all at once. Automatically skips already-split transactions and clears flags after processing.

3. Automatic 50/50 calculation
No manual math required. Handles all amounts correctly, including odd totals.

4. Custom partner settings
Configure your partner’s name, reimbursement category, and default memo (e.g. “Split with Nick”).

5. Fast, flexible workflow
Works whether you prefer cleaning up transactions in batches or splitting them as you go.

6. Secure and private
Uses the official YNAB API with your personal access token. No data is sent anywhere except YNAB, and all settings are stored locally in Chrome.
