About HourlyKit
HourlyKit is a small collection of free browser-based tools for checking work time, gross pay, overtime and salary conversions.
Clear results
What HourlyKit is for
Browser-based checks
Free tools help you check work time and gross-pay arithmetic in a browser.
Clear assumptions
Inputs and results are designed to be readable before they are copied or printed.
No account
Current P0 tools do not require an account.
Made for real questions
Reasonable uses
Personal timecard review
Check a shift or workweek before comparing it with another record.
Pay arithmetic
Convert salary, overtime, or raise assumptions into gross estimates.
Time conversion
Convert clock time and minutes to decimal hours.
What the tools are for
The tools turn clear work-time and pay assumptions into a readable estimate. They are designed for a quick self-check, not as an employer timekeeping system.
What HourlyKit does not provide
HourlyKit does not offer accounts, payroll processing, tax filing, legal determinations, employment advice or guaranteed pay outcomes. It does not claim ratings, user counts, offices or services that are not shown on this site.
Privacy boundary
The P0 calculators run in the browser. A time-card tool may save its inputs locally on the device so the user can return to them; see the Privacy Policy for the current behavior.
What to expect
Product boundaries
No payroll service
HourlyKit does not process payroll or submit time records.
No legal advice
It does not decide eligibility, compliance, or an amount owed.
Local timecard storage
The time card tool can save data in the browser on the same device.
Use a tool as a check
HourlyKit focuses on transparent arithmetic. Start with the calculator that matches the question, enter the assumptions, and review the visible result before using it elsewhere.
For example, a shift tool can subtract an unpaid break, while a salary tool can divide annual pay by stated annual work hours. Each is a gross estimate with a limited purpose.
Keep the limits in view
It is not an employer timekeeping system, tax service, legal service, or compensation adviser. No ratings, offices, user totals, testimonials, or integrations are claimed.
Use real records and appropriate guidance for an important decision. The privacy page describes current browser storage and the methodology page explains calculation behavior.
Check the stated assumptions
Use the visible inputs, formula, and result as one record. Confirm the units before copying a value: minutes versus decimal hours, weekly versus biweekly time, annual versus paycheck pay, and gross versus after-deduction amounts. A calculator result is easier to review when the original input and the assumption behind it remain visible together.
Read about HourlyKit as a practical estimate with a defined boundary. Check the displayed formula, use the linked tool for your own values, and compare material figures with actual records and current guidance. The source below provides general context where relevant; it does not replace an employer policy, tax record, contract, or individualized professional advice.
Understand the product before relying on it
HourlyKit has a narrow promise: provide free browser tools that make work-time and gross-pay arithmetic easier to inspect. It does not include payroll submission, employee accounts, tax filing, legal conclusions, employer integrations, or a guarantee that a formula matches every contract and jurisdiction.
The current product is useful for independent checks. Enter a shift to review paid duration, enter a week to review regular and overtime minutes, or enter salary assumptions to compare gross periods. Original records remain important; a calculator result should sit beside the schedule, pay statement, or offer being checked.
Privacy is part of the product boundary. The current version includes a Time Card draft stored locally in the browser, no account system, and no loaded analytics or advertising scripts. Those facts would need to be revisited if the architecture changes.
Trust comes from visible formulas, limitations, source notes, and reproducible examples. HourlyKit makes no claim of endorsements or professional status. Readers can inspect the methodology and editorial policy, then decide whether the tool is appropriate for a quick estimate.

HourlyKit provides transparent educational estimates. It is not an employer timekeeping system, payroll processor, tax service, or legal adviser.

No. The current calculators do not require an account, and the Time Card tool keeps its optional saved draft in the browser on the same device.
