A time period starting at the beginning of a year to the present. Year-to-date is also known as YTD.
Generally, year-to-date refers to a calendar year, but some businesses operate using a fiscal year. In that case, year-to-date would refer to the beginning of the fiscal year to the present.
Business owners often create year-to-date earnings or expense reports to measure their progress, comparing to year-to-date reports of previous years.
