It's Friday. How long do you still have to stay?
Your timesheet says 31 hours and 30 minutes, and you need 40 by the end of the week. Is that 8 hours today? 8 and a half? And what time is that, with lunch? If you're hourly, part-time, or working toward a set number of hours for a contract, a program or a paycheck, you do this math every week.
This calculator gives you the hours left and the exact time to clock out. If your goal is money instead, like earning enough for rent this week, it tells you how many hours that takes at your rate, with overtime counted.
How to use the calculator
Step 1
Choose your goal
Pick Hit an hours target for a weekly or contract hours goal, or Earn an amount for a money goal.
Step 2
Enter where you are
For hours, enter your target, what you've worked so far after breaks, and the workdays you have left. Add today's start time and break to get a clock-out time.
Step 3
Read your plan
See the hours left, the time to leave if you finish today, and the hours per day if you spread it out.

How it's calculated
Hours left = target − hours worked so far
Per day = hours left ÷ workdays left, rounded up to the minute
Leave at = start time + hours left + unpaid break
Hours to earn = amount ÷ rate, with hours past the overtime line at rate × multiplier
Let's say you need $1,000 at $20 an hour, with time and a half after 40 hours. The first 40 hours pay $800. The other $200 comes at $30 an hour, so it takes 6 hours 40 minutes more. That's 46.67 hours in total, instead of 50 without overtime pay.
Targets that aren't 40 hours
The hours target doesn't have to be a workweek. Use it for any number of hours you need to reach by a deadline:
- Part-time minimums. Some jobs and benefits require 20, 25 or 30 hours a week. Enter that as your target to see if you're on track.
- Contract and retainer hours. If a client pays for 80 hours a month, enter 80 and the workdays left in the month.
- Gig work. If you set your own schedule, an earnings goal is usually easier: enter what you want to make this week and your average hourly earnings.
- Training or volunteer hours. Enter the hours still required and the days you can come in. For OJT, the OJT Hours Calculator also skips weekends and holidays.
The days-left field goes up to 7, so it's meant for a week. For longer goals, divide by weeks first, then plan each week here.
Planning your hours
Front-load the week if you can. Hours you put in on Monday and Tuesday give you room if something comes up on Friday. And log your time every day, because the hours you remember at the end of the week are almost always fewer than the hours you actually worked.
If you're paid by the hour, check your rounding policy too. Some employers round clock-ins to the nearest 15 minutes, which can move your clock-out time. The Time Card Rounding Calculator shows how.
Watch the overtime line
In the US, overtime under the FLSA starts after 40 hours in a workweek, at 1.5 times your regular rate for non-exempt employees. A few states, like California, also count overtime per day. In the Philippines, overtime is per day: hours beyond 8 in a day are overtime and paid at least 125% on an ordinary day.
That's why the calculator warns you when your plan means more than 8 hours in a day. Long days can be fine, but your employer may need to approve the overtime, and some don't allow it. Spreading the hours over more days may be the better plan.
Questions about hours needed
How many hours do I need to work to reach 40?
Subtract what you have worked from 40. If you have 31 hours 30 minutes, you need 8 hours 30 minutes more. Starting at 8:00 AM with a 1-hour lunch, you can leave at 5:30 PM.
What time do I leave if I work 8 hours from 8 AM?
4:00 PM with no unpaid break, or 5:00 PM with a 1-hour unpaid lunch.
How many hours do I need to work to earn $1,000?
At $20 an hour, 50 hours. With time and a half after 40 hours in the same week, it is 46.67 hours, because the last $200 is earned at $30 an hour.
How many hours a day to reach 40 in 4 days?
10 hours a day. In 3 days, it is 13 hours 20 minutes a day.
Does the calculator count my lunch break?
Only as time you are at work, not time worked. Enter your unpaid break, and the clock-out time adds it on top of the hours you still need.
Will working extra hours today count as overtime?
In the US, overtime is usually counted after 40 hours in the week. In the Philippines, hours beyond 8 in a day are overtime. Check with your employer before staying late.
