I am filling in FI101's income / expenditure spreadsheet for July. 1. Is my income the income that arrived in my account in July for June's work, or the income that I received in June (for May's work) that is available to be spent in July? 2. Is my expenditure the cost of goods bought in July (even though I only pay off the credit card in August), or the money that left my account in July (to pay off the credit card bill for June's shoppping)?

not familiar with the spreadsheet, but there are 2 ways to do accounting, either accrual or cash. So either one is valid as long as you are consistent. With the budget tool I use, it’s simpler to count charges on your card as expenses, as opposed to when the debt is paid.

1. I would call the money that hits your account in june your june income 2. for the sake of budgeting, you should budget based off when you swipe the card, not when you pay off the card. YNAB forces you to do this nicely

What is FL101?
