See what overnight hours add to your pay
Nurses, warehouse and factory crews, security officers, and other overnight workers are often paid a night premium — also called a night differential — on the hours that fall overnight. Enter the premium as dollars per hour or a percentage of your base rate, how many night hours each shift has, and how many night shifts you are counting. The calculator shows the premium for one shift and for all of them, what those night hours pay in total, and the effective hourly rate. It is handy for weighing a switch to nights, checking a week of premiums, or estimating what extra overnight shifts are worth.
How to use the Night Shift Premium Calculator
- Type your base hourly rate.
- Choose whether the night premium is $ per hour or % of base rate, and type it.
- Type the night hours in one shift — only the hours that earn the premium — and the number of night shifts (1 by default).
- Read the night premium earned, the premium per shift, the total for those night hours, and the effective night rate. Copy Result copies a summary.
The formula
Night premium per hour = flat amount, or base rate × % ÷ 100
Night hours = night hours per shift × shifts
Night premium = premium per hour × night hours
When a shift crosses midnight, count only the hours inside your premium window. With an 11 p.m. to 7 a.m. window, a 7 p.m. to 7 a.m. shift has 8 night hours, and a 3 p.m. to 11:30 p.m. shift has half an hour. The total premium is worked out on all the night hours at once and rounded to the cent, so it can differ by a few cents from the rounded per-shift premium times the number of shifts.
| Rate, premium, and night hours | Night premium | Total pay |
|---|---|---|
| $18.50 + $1.50/hr, 8 h × 5 shifts | $60.00 | $800.00 |
| $24.00 + 15%, 7.5 h × 1 shift | $27.00 | $207.00 |
| $30.00 + 10%, 10 h × 4 shifts | $120.00 | $1,320.00 |
| $21.75 + $2.00/hr, 8 h × 12 shifts | $192.00 | $2,280.00 |

Night Shift Premium Calculator FAQ
- How is a night shift premium calculated?
- Premium per hour × night hours. With a $1.50-an-hour premium, 8 night hours a shift, and 5 shifts, the premium is $1.50 × 40 hours = $60.00. At an $18.50 base rate, that brings the total for those hours to $800.00.
- Is a night differential the same as a night premium?
- They usually mean the same thing: extra pay for working overnight hours. Some employers say "night differential," some "night premium," and some fold it into a general "shift differential." The arithmetic is the same whichever name your employer uses.
- Which hours count as night hours?
- Whatever your employer’s policy says. A common rule pays the premium only for hours inside a window, such as 11 p.m. to 7 a.m.; then a 7 p.m. to 7 a.m. shift has 8 night hours, not 12. Other policies pay it on every hour of a shift that is mostly overnight. Enter the hours that actually earn it.
- Why doesn’t the per-shift premium times the shifts match the total exactly?
- The per-shift figure is rounded to the cent, while the total multiplies the rate by all the night hours at once. With a rate like $2.082 an hour, 7.5 hours is $15.615 → $15.62 a shift, but 37.5 hours is $78.075 → $78.08, not 5 × $15.62 = $78.10.
- Does it include overtime, taxes, or deductions?
- No. These calculations estimate pay from the rates and hours you enter. They do not account for overtime rules, taxes, deductions, employer policies, union agreements, or other payroll rules.
- Are night premiums required?
- The calculator doesn’t decide that. Whether overnight hours earn a premium, and at what rate, depends on your employer, your agreement, and the rules where you work. It only multiplies the premium you enter.
- Are the amounts I enter sent anywhere?
- No. The calculation runs in your browser as you type. The amounts, rates, and results are not sent to Looty Tools or stored, and the calculator area is masked from session-recording analytics. Refreshing the page clears it.
