About PTO Calculator Hub | PTO Calculator Hub

What is PTO Calculator Hub?

PTO Calculator Hub is a free resource site that helps employees, HR professionals, and business owners answer common paid time off questions. We provide interactive calculators, reference charts, and educational guides covering PTO accrual, payout calculations, vacation tracking, holiday pay, overtime, and sick leave.

PTO policies are often confusing. Accrual caps, rollover rules, payout requirements, and state-specific labor laws create a patchwork that most people struggle to navigate. This site exists to make that information clear, accurate, and immediately useful — without requiring a call to HR or a consultation with a payroll specialist.

Our tools and resources

9 interactive calculators: PTO per paycheck, balance projection, payout value, hours-to-days, vacation tracking, holiday pay, overtime, sick leave, and rollover forecasting
Reference data: Accrual rate charts by tenure and industry, 50-state payout law comparison, and a downloadable Excel tracking template
Educational guides: In-depth articles explaining accrual methods, payout rules and taxes, hourly worker rights, and negotiation strategies

How we build our calculators

Every calculator on this site follows established payroll arithmetic used by HR departments and payroll software providers. We do not invent new formulas — we implement the same math that ADP, Workday, and Gusto use internally, then present it in a simple interface anyone can use.

Our development process for each calculator:

Research the formula: Cross-reference SHRM payroll guidelines, IRS publications, and state labor codes to identify the correct calculation method
Build and test: Implement the calculation in JavaScript (runs entirely in your browser), then test against known payroll examples
Document the logic: Each calculator page explains the formula in plain language with a worked example, so you can verify the output manually
Review and update: When tax rates, salary thresholds, or state laws change, we update the relevant calculator and note the revision date

Where our data comes from

We cite our sources directly on each page. The primary references we use across the site include:

Bureau of Labor Statistics (BLS) — National Compensation Survey data for average PTO days by tenure, industry, and employer size
IRS Publication 15 — Federal supplemental wage withholding rates (22% flat rate for PTO payouts and overtime)
Society for Human Resource Management (SHRM) — Payroll best practices, accrual method definitions, and employee benefits survey data
U.S. Department of Labor — Fair Labor Standards Act (FLSA) overtime requirements and wage-hour rules
State labor department websites — For state-specific PTO payout laws, sick leave mandates, and overtime thresholds (California DLSE, Colorado CDLE, etc.)

Privacy and data handling

All calculations run entirely in your browser using client-side JavaScript. We do not:

Store your salary, hours, PTO balance, or any input you enter into a calculator
Transmit calculation inputs to any server
Require account creation, login, or email signup
Sell or share any user data with third parties

We use Google Analytics to understand which pages are most useful and how visitors find us. This collects anonymized traffic data only. See our full privacy policy for details.

Editorial standards

We hold our content to the following standards:

Accuracy: Every legal claim, tax rate, and formula is verified against official government sources before publication. Each page includes source citations.
Currency: Content includes visible "last updated" dates. We review pages when relevant laws change (e.g., new state sick leave mandates, IRS rate adjustments, FLSA salary threshold updates).
Transparency: We clearly state that our tools provide estimates. We are not a law firm, accounting firm, or licensed HR consultancy. Our disclaimer specifies the limits of our content.
Corrections: If you find an error on any page, contact us. We investigate promptly and correct verified inaccuracies within 48 hours.

Limitations

While we strive for accuracy, there are things this site cannot do:

We cannot account for your employer's unique internal policies (custom vesting schedules, probationary periods, etc.)
Our tax estimates use standard withholding rates; your actual tax liability depends on your full income picture
We do not provide legal advice — for disputes about unpaid PTO, consult an employment attorney or file a claim with your state's Department of Labor
State law information is current as of our last review date but may change between updates
