Fiscal Year Calculator

A fiscal year is a 12-month accounting period that does not have to match the calendar year. It begins on the first day of a chosen start month and ends on the day before that month one year later. For example, a fiscal year that starts on October 1 ends on September 30 of the next year.

The US federal fiscal year runs from October 1 through September 30. It is named for the calendar year in which it ends, so the year that runs October 1, 2025 to September 30, 2026 is fiscal year 2026 (FY2026). Pick the US federal preset to use these dates.

Each fiscal year is split into four quarters of three consecutive months, starting from the first month of the fiscal year. Q1 covers months 1 to 3, Q2 covers 4 to 6, Q3 covers 7 to 9, and Q4 covers 10 to 12. With an October start, Q1 is October to December and Q3 is April to June.

It depends on the convention you follow. The US federal government and many US organizations name the fiscal year for the year it ends, while several governments and companies name it for the year it begins. This tool lets you choose either, and it always shows the full span label (such as FY2025-2026) so there is no confusion.

Yes. Choose the custom preset and select any start month from January to December, then pick whether to label the fiscal year by its start or end year. This covers common schedules like an April 1 start (used in the UK, India, Canada, and Japan) and a July 1 start (used in Australia and New Zealand).

No. It gives an estimate of the fiscal year, quarter, and period dates based on the start month you choose, and it is not financial, tax, or accounting advice. Confirm your organization's official fiscal calendar and any tax deadlines with a qualified professional or the relevant authority.
