Contact Us

You can reach us to report a bug, suggest a new calculator, request a correction, ask about how a tool works, or flag anything on the site that seems off.

When reporting a calculation issue, it helps to include the page URL, the values you entered, and what result you expected. That extra detail — especially for date, timezone, or payroll tools — lets us find and fix the problem much faster.

For all inquiries, please email us directly at:

If a calculator is giving you a wrong or unexpected result, tell us which page you were on, the values you entered, and what you expected to see. The more specific you are, the faster we can reproduce the issue and fix it.

This is especially useful for tools involving dates, time zones, shift hours, or overtime — where even a small difference in inputs can change the output significantly.

If you have an idea for a new calculator, a missing explanation, or something that would make the site more useful, we'd like to hear it. We give priority to requests that come from everyday tasks — payroll, scheduling, budgeting, tax estimates, and planning.

• Broken pages, display issues, or incorrect calculator results.
• Unclear explanations, missing FAQ answers, or content corrections.
• Requests for new tools or additional guides.

Please note that we can't give personal legal, tax, payroll, medical, or financial advice. But if a page on our site seems wrong or unclear, we're happy to take a look.

Every message is read by the team at DP Tech Studio. Depending on the issue, we'll test the calculator, check the page, update the explanation, or revise the content if a correction is needed. Not every suggestion turns into a new feature straight away, but we take genuine feedback seriously and it does shape what we work on next.
