Estimates for guidance only
All Time Ledger calculators are provided for general informational purposes only. Every result is an estimate based solely on the numbers you enter. They are not professional advice, official records, or a guarantee of any outcome, and you should independently verify anything that affects pay, contracts, safety, or spending before relying on it.
Pay & time tools — not payroll or legal advice
The time card, overtime, work-hours, and related tools produce estimates of gross pay and hours before taxes, insurance, or other withholdings. They are not a pay stub, an employment record, or a statement of wages owed, and nothing here is legal, tax, accounting, or financial advice. Overtime and working-time rules differ by country, state, industry, and contract — always confirm your entitlements with your employer or a qualified professional.
Stair & construction tool — not engineering advice
The stair stringer calculator is a workshop aid, not a substitute for local building codes, structural engineering, or a qualified carpenter. Riser, going, headroom, and stringer figures are guidance based on common conventions and may not meet the building regulations that apply to your project. Always check your local code, measure twice, and cut a test piece before committing timber. We accept no responsibility for materials, injury, or work carried out using these figures.
Accuracy & liability
We publish every formula our calculators use and work to keep the math correct, but the site is provided "as is" without warranty of any kind, express or implied. We do not guarantee that results are error-free or fit for any particular purpose, and we accept no liability for decisions made, or losses incurred, in reliance on them.
