Hours Calculator Online is published by beFortunate, a company based in the Netherlands that builds focused, practical online tools, as a free reference tool. This page explains what the calculators are for, and what they are not for, so you can judge how much weight a result will bear.

Arithmetic, not advice

Every tool on this site performs a defined calculation on numbers you type in. It converts clock times to minutes, subtracts one from another, deducts a break, applies thresholds and a multiplier you chose, and converts the answer to decimal hours. Each step is documented on the how it works page and can be reproduced on paper.

Nothing on this site constitutes legal, employment, payroll, tax or financial advice, and no professional relationship is created by using it. We are software developers, not lawyers or payroll professionals, and we do not hold ourselves out as qualified to advise on wage law.

The distinction is practical. A calculator can tell you that 44 hours at a 40-hour threshold leaves 4 hours above the line. It cannot tell you whether that threshold is right for your job, whether those hours attract a premium, or whether you are owed anything.

What the calculators do not know

A result reflects the figures you entered and nothing else. The calculators have no knowledge of:

• Your jurisdiction. Overtime thresholds, break entitlements, maximum working hours and night-work protections vary by country, and often by state, province or sector within one.
• Your contract or collective agreement. These frequently set terms more generous than the statutory minimum, including different thresholds and enhanced rates.
• Which breaks are paid. Whether a rest period counts as working time depends on local rules and on what actually happened — an interrupted lunch is often a different matter from an uninterrupted one. The calculator deducts the break minutes you enter, no more and no less.
• Your employer's rounding policy. Many time clocks round punches to the nearest quarter hour. Our figures use the exact times you entered, so they can legitimately differ from a system that rounds.
• Premiums and differentials. Night, weekend, holiday and shift premiums, on-call pay, bonuses and tips are not modelled anywhere on this site.
• Deductions. Pay figures are gross. No income tax, social contributions, pension or any other withholding is applied.
• Paid leave. Holiday, sick leave and public holidays are not calculated, and whether such hours count toward an overtime threshold is a legal question we do not answer.
• Daylight saving time. A shift spanning a clock change may be an hour longer or shorter in real time than the two clock times suggest.

Where our guides mention a specific figure — a 40-hour week, an 8-hour day, a 1.5× multiplier — it is an illustration chosen because it is common, not a statement about your entitlement. Our overtime guide explains how such thresholds interact and is explicit that the ones applying to you come from your own law, contract or agreement.

Accuracy and its limits

We take the arithmetic seriously. All times are handled as whole minutes so no rounding drift can accumulate, decimals are produced only at the final step, and the calculation module is covered by 50 automated unit tests that run on every change. The method is set out on our about page.

Even so, the site is provided "as is", without warranty of any kind. We do not guarantee that it is free of errors or suitable for your situation. Software can contain bugs, and a rule we have described may have changed since we last reviewed the page.

There is also a limit no testing can remove: a calculation is only as good as its inputs. A mistyped digit, a start and end entered the wrong way round, a break in hours where minutes were expected — each produces a confident, precise and wrong answer. The calculator rejects what it can detect, such as a break longer than the shift it belongs to, but it cannot know that 9:30 should have been 7:30.

Your responsibility before relying on a result

You are responsible for checking any figure that matters. Treat the output as a second opinion rather than a source of truth:

1. Re-read your inputs before you read the answer. Most surprising totals are a typo, not a fault in the arithmetic.
2. Sanity-check the magnitude. If a normal week comes out at 68 hours, something is wrong somewhere.
3. Compare against your own records — a payslip, a punch report, last month's invoice — before submitting anything.
4. Confirm the rules with an authoritative source for where you work, not with a calculator's default settings.
5. Keep your own records. The site stores nothing for you, so an exported CSV or a printout is yours to retain.

Not a time-keeping or payroll system

This is a calculator, not a record-keeping system. It has no audit trail, no approval workflow and no way to prove when a figure was produced; anything saved on your device is a convenience against an accidental reload, and clearing site data erases it.

An output from this site is therefore not evidence of hours worked and will not satisfy a statutory record-keeping obligation. Employers who must keep time records should use a system built for that purpose. Employees preparing a wage claim should rely on contemporaneous records — rotas, punch reports, diaries — which a calculator can help add up without becoming the record itself.

Third-party content and advertising

The site is free and funded by advertising through Google AdSense. We do not select, review or endorse the individual advertisements displayed, and their presence implies no recommendation of the advertiser. Judge any advertised offer on its own merits.

Where a guide links to an external source, such as a government page, we link because it is authoritative at the time of writing. Our privacy policy explains what the advertising involves.

Currency of the information

Pages carry a review date; everything on the site was last reviewed 1 November 2026. Wage rules change, and a page accurate when written can fall out of date without any visible sign. We revise pages when we learn something has changed, but we do not monitor legislation in every country. Always verify time-sensitive rules against a current official source.

Where to get real advice

If you have a question this site cannot answer, the right place depends on what you are asking:

• Your pay looks wrong. Start with your employer's payroll or HR department; most discrepancies are errors that are simply corrected.
• Your rights are unclear. Consult your contract and any collective agreement, then your union representative, a labour authority, or an employment lawyer.
• You run payroll for a business. Use payroll software or an accountant. Correct withholding and reporting are legal obligations this site does not address.
• You are disputing hours or pay formally. Get qualified advice before filing anything. A calculator cannot assess the strength of a claim.

Reporting a problem

If you believe a calculator produces a wrong result, we want to hear about it. Send the exact inputs, the result shown and the result you expected, and we can turn it into a test case. The contact page explains what to include.

If you spot an inaccuracy in a guide, tell us the same way.

This disclaimer should be read with our terms of use, which set out the limitation of liability and the governing law. In any inconsistency, the terms prevail.
