Income, Taxes, Expenses, Savings
Income entries are for the before-tax amount of money you earn through your job and other sources.
Tax entries are for the income-based tax you pay to your local and federal government. This may include general taxes or taxes earmarked for specific things (i.e. Social Security). Other taxes (i.e. property taxes and sales taxes) should be included in Expenses along with other spending in their categories.
Savings entries are for money put toward the long-term - typically things that build net worth.
Expense entries are for any instance where money leaves your hands or accounts other than savings. This includes everything from groceries to health care premiums and copays.
Rates (Tax, Expense, Saving)
Rates are calculated as a percentage of your Income for the same time period.
