Add the hours together, then add the minutes together. If the minutes total 60 or more, convert each 60 minutes into 1 hour. For example, 3 hours 45 minutes plus 2 hours 30 minutes equals 5 hours 75 minutes, which converts to 6 hours 15 minutes. This calculator handles the conversion automatically.
Divide the minutes by 60 and add to the hours. For example, 7 hours 30 minutes equals 7.50 decimal hours (30 / 60 = 0.50). Common conversions: 15 min = 0.25, 30 min = 0.50, 45 min = 0.75. Decimal hours are required for payroll and billing calculations.
Hours:minutes format (7:30) shows time in a clock format. Decimal hours (7.50) represent time as a fraction. Payroll systems and billing software use decimal hours because you can multiply them directly by an hourly rate. For example, 7.50 hours at $40/hour equals $300.
Enter your hours and minutes worked for each day of the week. The calculator adds them up and shows the weekly total in both decimal and hours:minutes format. For overtime calculations, compare the total to 40 hours. Any hours over 40 are typically paid at 1.5x under FLSA rules.
Yes. Automatic time tracking software like Rize captures every work session in the background without manual entry. Instead of adding up hours at the end of the week, your total hours are calculated in real time as you work. The data is ready for payroll, client billing, or project tracking without any manual calculation.
For payroll, you need total hours in decimal format. Add up all hours and minutes worked, convert to decimal (divide minutes by 60), then multiply by the hourly rate. Subtract any unpaid break time before calculating. This calculator gives you the decimal total directly.
A standard full-time work year is 2,080 hours (40 hours per week times 52 weeks). After subtracting federal holidays and typical PTO, the average American works about 1,800–1,900 hours per year. Use this calculator to track your actual hours and compare them to the standard.
Enter the hours and minutes you worked each day of the week into the calculator. It adds them automatically and displays the weekly total in both decimal and hours:minutes format. Compare against 40 hours to check for overtime eligibility under FLSA rules.

Payroll requires hours in decimal format, not hours and minutes. To convert, divide the minutes by 60 and add to the whole hours. For example, an employee who worked 38 hours and 45 minutes has 38.75 decimal hours. At $22/hour, gross pay is $852.50.
Common minute-to-decimal conversions: 5 min = 0.08, 10 min = 0.17, 15 min = 0.25, 20 min = 0.33, 30 min = 0.50, 45 min = 0.75. This calculator converts automatically so you can copy the decimal total directly into your payroll system.
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 5 | 0.08 | 35 | 0.58 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
| 25 | 0.42 | 55 | 0.92 |
| 30 | 0.50 | 60 | 1.00 |
Formula: decimal = minutes ÷ 60. This calculator applies the conversion automatically.
Agencies and consultants bill by the hour across multiple clients and projects. Use the description field to label each entry with the client or project name, then use the decimal total for invoicing. For example, “Website redesign: 12.25 hours at $150/hour = $1,837.50.”
Manual hour tracking creates billing disputes. According to the American Payroll Association, manual time entry has a 1-8% error rate. For agencies billing $100-250/hour, a 5% error on a 40-hour project means $200-500 lost per project. Automatic time tracking captures every work session without manual entry, eliminating billing errors.
The standard US work week is 40 hours. The Bureau of Labor Statistics reports the average American works 38.7 hours per week. Under the FLSA, non-exempt employees earn overtime (1.5x rate) for hours exceeding 40 in a single work week.
Freelancers and consultants typically aim for 25–30 billable hours per week, with the remaining time spent on admin, sales, and non-billable work. Use this calculator to total your weekly hours and compare against your target.
An hours calculator requires you to know your hours before entering them. You still need to track time manually — writing it down, remembering at end of day, or using a timer. The calculator just does the math.
Automatic time tracking captures hours as you work. No timers, no manual entry, no end-of-week reconstruction. Your weekly total is always accurate and ready for payroll or billing without needing a calculator at all.
