In terms of the differences between YNAB vs. Mint, cost and function are largely what set them apart. YNAB requires a monthly or yearly fee while Mint doesn’t. YNAB uses spreadsheets to manage your budget on a forward-looking basis, which could work well for you if you’re spreadsheet-savvy. Mint, on the other hand, is an app that makes it easier to manage your current monthly budget from your mobile device, any time or anywhere.
