Notice Period Calculator

Resigning raises two quick questions: when is my last working day, and what happens if I want to leave sooner? The answers depend on how your contract defines the notice period, but the arithmetic is the same every time. This page does the date calculation and the buyout estimate so you can check a figure before you have the conversation with your manager or HR.

From notice to last day

Enter the date you give notice, the length of the notice, and whether it is counted in days or months. For days, the page adds that many calendar days. For months, it moves the date forward by that many months, and if the target month is shorter, such as 30 January plus one month, it lands on the last day of February. The result shows the last working day with its weekday, so you can see at a glance that it falls on a Sunday.

Leaving earlier than the notice allows

Add the day you would like to finish, and the page compares it with the end of the notice. It prints how many days of the notice you would serve, as a count and a percentage, and how many days short you are. If your employer allows you to use accumulated leave in the notice period, enter the leave days, and they are subtracted from the shortfall. What remains is the number of days to buy out.

The buyout

The buyout is the remaining days multiplied by a daily rate, which the page takes as the monthly pay divided by 30. Employers differ on what monthly pay means: some use gross, some basic pay, and some recover nothing or ask for a fixed fee. The pay box is labelled as the figure your employer uses for the buyout, so enter the one in your contract.

A worked example

The default is notice given on 2 March 2026, for 90 days. The last working day is 31 May 2026, a Sunday. If you want to leave on 15 May, you serve 74 of the 90 days, or 82 percent, and are 16 days short. Five leave days cover part of it, which leaves 11 days to buy out. At a monthly pay of 90,000, the daily rate is 3,000, so the buyout is 33,000. The second sample gives a two-month notice from 10 June 2026. The last day is 10 August 2026, a Monday, which is 61 days later. Leaving on 31 July is 10 days short, 3 leave days cover some, and 7 days cost 21,000.

Edge cases

An exit date later than the last day gives a shortfall of zero, since staying longer does not cost anything. A leave balance larger than the shortfall is shown as only the days actually used. Dates must be typed as YYYY-MM-DD, and an invalid date shows an error with an example. A notice of 0 ends on the same day, and the maximum accepted is 1,000.

Weekends and holidays

The page counts every calendar day, including weekends and public holidays. Contracts that count only working days will give a different answer, so convert the notice yourself before entering it, or treat the result as an upper bound. The page does not know company holidays. If the last day falls on a weekend, many employers shift the exit date, which is a matter for your HR team and not something the page can decide.

Limits

The page does not read your contract. It cannot tell you whether the employer must accept a buyout, whether leave can be adjusted, or whether other recoveries such as a joining bonus apply. Statutory rules and individual contracts differ, and the notes under the result say to read the offer letter and company policy. Treat the buyout as an estimate for discussion.
