About DeluxeCalc
About Us
DeluxeCalc is a free collection of online calculators for money, health, math, and everyday conversions. It covers four areas: financial, fitness and health, math, and utility tools, from mortgage payments and retirement savings to body mass index, statistics, and unit conversion.
We built DeluxeCalc around three ideas. Calculators should be fast, so results update as you type. They should be private, so the arithmetic happens in your browser rather than on our servers. And they should be shareable, so every result has its own link you can bookmark or send to someone else.
Each calculator comes with a guide that explains the formula it uses, works through an example, and points out its limitations. Every calculation is checked by an automated test suite before changes go live. Even so, results are estimates that depend on the inputs and assumptions involved, and they are not a substitute for advice from a qualified professional.
Frequently Asked Questions
- Is DeluxeCalc free?
- Yes. Every calculator is free to use, with no sign-up and no limit on how often you use it.
- Do you store the numbers I enter?
- No. Calculations run in your browser and your inputs are not sent to us. The inputs are written into the page address so you can bookmark or share a result, which means anyone you send the link to can see them. Avoid sharing links that contain information you want to keep private.
- Can I link to a calculator or share my results?
- Yes. You are welcome to link to any page on DeluxeCalc. Copying the page address after entering your numbers gives a link that reopens the calculator with the same inputs.
- I found an error. How do I report it?
- Please email us with the calculator name, the link showing the inputs you used, the result you got, and the result you expected. Reports like this are the fastest way for us to find and fix a problem.
- Do you offer an API?
- Not at this time.
- Is this financial, medical, or legal advice?
- No. Results are estimates based on the formulas and assumptions described on each page. Talk to a qualified professional before making decisions that depend on them.

Privacy Policy
Last updated: October 31, 2026
This policy explains what information DeluxeCalc handles when you use the site and how it is used. By using DeluxeCalc you agree to this policy.
Information you enter into calculators
Calculations are performed in your browser. The values you type are not sent to us or stored by us. To make results shareable, the values are placed in the page address (the URL). The address stays in your browser history, and anyone who receives a link you share can see the values in it. When a page is loaded from a link, the full address, including those values, is sent to our hosting provider as part of the request.
Downloads
PDF and CSV files you download are created in your browser from the results on your screen. They are not uploaded to or kept on our servers.
Server logs
Like most websites, the servers that deliver DeluxeCalc automatically record basic technical information about each request, such as your IP address, browser type, the page requested, the referring page, and the time of the request. This information is used to operate, secure, and troubleshoot the site, and it is retained according to our hosting provider's practices. We do not use it to identify you personally.
Cookies, analytics, and advertising
DeluxeCalc does not currently use cookies, analytics services, or advertising. If that changes, we will update this policy before doing so and describe what is collected and any choices available to you.
Accounts and personal information
DeluxeCalc has no user accounts, and we do not ask for your name, email address, or other personal information to use the calculators. If you email us, we use your message and address only to respond to you and to improve the site, and we do not sell or share them.
Children's privacy
DeluxeCalc is a general-audience site and does not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, please contact us and we will delete it.
Security
The site is served over an encrypted connection. No method of transmission or storage is completely secure, however, so we cannot guarantee absolute security.
Links to other websites
Pages may link to websites we do not control. We are not responsible for their content or privacy practices, and we encourage you to read their policies.
Changes to this policy
We may update this policy from time to time. The date at the top shows when it last changed, and continued use of the site after a change means you accept the updated policy.
