Find your last working day from the resignation date and notice period, see how many days are left, and estimate a notice buyout.
Employers work out buyouts differently. Some use basic pay, others gross pay; some divide by 30, others by the working days or the days in that month. Your offer letter or HR policy decides.
Once you hand in your resignation, three questions follow almost at once: which date is my last day, how many days do I still have to serve, and what would it cost to leave sooner. This calculator answers all three from two inputs, the date you resign and the notice period written in your appointment letter. It is useful for anyone serving notice, for a new employer planning a joining date, and for HR teams who want to double check a relieving date before they put it in writing.
Notice clauses are written in two ways, and they do not always give the same answer. A clause that says "60 days" means sixty calendar days, weekends and holidays included. A clause that says "two months" follows the calendar, so the length depends on which months you cross. The tool handles the awkward cases correctly. If the notice starts on 31 January and runs for one month, there is no 31 February, so the period ends on the last day of February: 28 February, or 29 February in a leap year. A three month notice that starts on 30 November likewise ends on the last day of February, not in early March.
The other setting that changes the answer is the starting day. Many companies count the resignation date as day one of the notice; others start the next morning. Pick the option your HR policy uses. If you are not sure, check your resignation acceptance email, which usually states the relieving date.
Priya resigns on 1 September 2026 with a 90 day notice that starts on the resignation day. Her last working day is 29 November 2026. Her new employer wants her to join on 16 November, so she asks to buy out 15 days. Her company recovers notice pay on basic pay of Rs. 45,000 a month, divided by 30, so one day costs Rs. 1,500 and the buyout comes to Rs. 22,500. Her last day after the buyout moves to 14 November. If her employer divided by 26 working days instead, the same 15 days would cost about Rs. 25,962.
A buyout is a payment you make, or a deduction from your final settlement, in place of serving part of your notice. Whether a buyout is allowed at all is your employer's decision, and many companies also let you set off unused earned leave against notice days, which this tool does not assume. Some new employers reimburse the buyout as part of the offer, so ask before you pay. Treat the amount here as an estimate of the base figure; the final settlement statement shows the exact recovery.
The weekday count simply skips Saturdays and Sundays; it does not know your company's holiday list or shift pattern. The calculator is a planning aid, not legal advice. Your employment contract, standing orders and any law that applies to your role take precedence, and the date on your relieving letter is the one that counts.
