Partner Disclosure
This site is free to use. This page explains how it earns money and how we keep that separate from the numbers.
How The Site Earns Money
The site earns money from display advertising, and may earn a commission if you buy a product through a partner link. A link of that kind is always marked.
You pay the same price whether or not you use a partner link.
Where Partner Links Appear
Partner links appear only on a few pages, such as the printable timesheets and the guide to hours in Excel. They point to time-clock tools built for employers who manage a team.
Partner links are never placed inside the calculators, and they never change a result.
How Links Are Marked
Every partner link is labelled on the page and carries the sponsored and nofollow link attributes, so search engines know it is paid.
Independence
- Calculations come from one engine and are not changed by any advertiser or partner.
- Rules come from official sources, not from partners.
- A partner cannot pay to be mentioned in a guide.
