Nights, your hike, and what you take home.

Night shift hours, allowance, and differential

A night shift allowance calculator answers “what does a month of nights pay?” A night shift hours calculator answers “how long was this roster?” They are different questions. If you have a start time and an end time, including a shift that runs past midnight, use the hours and differential calculator. 22:00 to 06:00 is 8 hours. 20:00 to 05:00 is 9 hours, of which 7 sit inside a 22:00–06:00 night window and 2 do not. Break minutes are spread across the shift, because the form does not ask when you took the break.

Shift pay is those hours times an hourly wage, plus a night differential only if you type one. There is no single India-wide statutory percentage to drop in. Many software teams instead pay a slice of daily CTC or a fixed rupee amount per night — that is the Nights tab on this page, and the allowance guide. State hours rules and overtime are separate from that premium. The letter and the payslip win.

What this site is for

Software rosters rarely print the working behind night-shift allowance. Appraisal letters quote CTC, not in-hand. This toolkit is a public set of calculators plus original guides so you can sanity-check a month of nights, a hike %, and a simplified new-versus-old tax fork without creating an account.
