Regular line
regular amount = regular hours × base rate
This line remains separate so the ordinary portion of the gross estimate can be checked without working backward from a total.
Time and a Half Calculator
The time and a half calculator prices regular, 1.5×, and optional 2× hours from one base hourly rate. Each line and the gross estimate are rounded through integer cents. You supply the hour categories; the tool supplies transparent multiplication, not an overtime eligibility decision.
Time and a half calculator — hours and rate in, gross estimate out
Hourly arithmetic · line-by-line cent rounding · no tax calculation
This tool multiplies the hours you classify; it does not decide which hours are overtime. It is an arithmetic estimate, not payroll or legal advice. Jurisdiction rules differ, and our methodology page covers sources.

HOW IT WORKS
Building an overtime pay estimate
FIG. 1 — RATE MULTIPLIERS
Time and a half calculator formula
premium rate = base rate × 1.5
How base and regular rates stay separate
The factor changes the rate. It does not change, create, or independently classify the hours entered in that line.
How premium lines become a gross total
Double-time line
double amount = double hours × base rate × 2
Zero or a blank field contributes nothing. The line is optional because a 2× category does not apply to every record or policy.
Integer-cent total
gross = round(line 1) + round(line 2) + round(line 3)
Each computed pay line is rounded to whole cents before the lines are added, avoiding a drifting binary-fraction total.
Precision and classification boundaries
The base rate is entered with up to two decimal places, while hours can carry up to four. The displayed 1.5× and 2× rates pass through the same cent formatter as a one-hour pay line. The regular, premium, double, and combined amounts all use the shared gross-pay routine, which calculates in integer cents at the line boundary.
A premium calculation is only as meaningful as its inputs. If a recorded total is 45 hours, this page cannot infer that five belong in the 1.5× field. The user might have a different workweek, an agreement with another structure, an excluded category, or a jurisdiction-specific rule. Classification therefore stays outside the arithmetic.
Price classified hours in three steps
03 STEPS- 01
Enter one base rate
Use the hourly rate that is appropriate for this arithmetic check. Two decimal places are accepted. The page does not derive a regular rate from salary, bonuses, commissions, or other compensation.
- 02
Place hours in known categories
Enter regular, time-and-a-half, and optional double-time hours only after you have decided their categories. Decimals such as 5.5 are accepted when the source record includes a partial hour.
- 03
Audit the lines
Compare the displayed multiplier rates, each line amount, and the gross. Open the calculation lines to see the same operations in order, then copy or share the estimate if useful.
No schedule is analyzed and no automatic overtime detection runs here. The calculator does not estimate withholding, tax, benefit deductions, reimbursements, or net pay. It provides three gross multiplication lines for categories supplied by the user.
Hourly premium pay scenarios
INPUT → RESULTTime and a half calculator worked total
40 h × $20.00 = $800.00
5 h × $30.00 = $150.00
gross = $950.00The $30.00 rate comes from $20.00 × 1.5. No double-time hours are entered in the prerendered case.
A partial premium hour
$18.40 × 1.5 = $27.60/h
2.5 h × $27.60
= $69.00Decimal hours multiply directly. A separate clock conversion can be useful when the source says 2 hours 30 minutes.
Regular plus two premium levels
32 h × $24 = $768
4 h × $36 = $144
2 h × $48 = $96
gross = $1,008Keeping three lines visible makes it possible to locate a rate or hour-entry mistake before relying on the sum.
Hours alone do not classify themselves
entered total: 45 h
regular field: user choice
premium field: user choiceThe same 45-hour total can produce different arithmetic when a user supplies different categories. This page does not choose one.
If the source record is written as HH:MM, first use the clock-to-decimal tool. If the hours still need to be totaled from daily arrivals, departures, and lunch deductions, begin with the weekly card tool.
Classification, policy and pay limits
CHECK BEFORE USERate with half-cent premium
A base rate such as $19.99 produces an exact 1.5× value of $29.985. Currency displays need cents, so the one-hour rate display rounds, and each pay line independently rounds its computed amount to cents.
Blank and zero differ visually, not mathematically
A blank optional hours field is treated as zero for the estimate. Zero can be entered explicitly when the record should show that the category was considered but had no hours.
Gross is not take-home pay
The output precedes taxes and deductions. It also excludes tips, bonuses, commissions, shift differentials, reimbursements, and any other item that is not represented by the three visible lines.
Rounding can differ elsewhere
A payroll system may carry additional precision or apply a policy at another stage. This estimate uses the transparent rule stated here: each hours-times-rate line becomes integer cents, then those cents are summed.
The page multiplies hours that you classify and never decides which hours are overtime. It is an arithmetic estimate rather than payroll or legal advice. Rules vary by jurisdiction and circumstance; our methodology page describes the site's sourcing approach.
Sources and standards
REFERENCE NOTESFor federal overtime context, see the U.S. Department of Labor's Fact Sheet #23: Overtime Pay Requirements of the FLSA. Jurisdictions differ — California, for example, states:
“a nonexempt employee shall not be employed more than eight hours in any workday or more than 40 hours in any workweek unless he or she receives one and one-half times his or her regular rate of pay”

Premium-rate questions
TAP TO OPENWhat is time and a half of $20 an hour?+
Multiply $20 by 1.5 to get a $30.00 premium hourly rate. If five hours are placed in that line, the amount is 5 × $30.00 = $150.00. Forty regular hours at $20.00 add $800.00, producing the worked default gross estimate of $950.00.
How should I count the hours?+
You decide which hours belong in regular, 1.5×, or 2× categories based on the records and rules that apply to you. The calculator only multiplies the categories you enter. It does not inspect a schedule, identify a workweek, or decide whether a particular hour legally qualifies for a premium.
How does double time work here?+
The double-time line uses two times the entered base hourly rate. At $20.00 per hour, the displayed double-time rate is $40.00. Enter only hours you have already classified that way; leaving the optional field blank or at zero contributes $0.00.
Can a salaried employee use this estimate?+
This tool is hourly arithmetic only. It does not convert a salary into a legally applicable regular rate, evaluate exemptions, allocate bonuses, or determine eligibility. A salaried person should use an hourly rate supplied by an appropriate payroll source if a simple multiplication check is actually needed.
