FAQ
- How does CalculateEveryday make money?
- The site is funded by 16 sponsor slots at $10/day with volume discounts for longer bookings, and a $5/month option to embed a calculator without the CalculateEveryday watermark. There are no ads, programmatic exchanges, retargeting pixels, sponsored calculators, or data sales.
- What quality standards are applied to the calculators?
- Formulas are checked against primary sources like regulators, standards, or textbook derivations, not other calculator sites. Money is computed in integer minor units to avoid floating-point rounding drift. Every page lists assumptions and edge cases where the answer stops being useful.
- Can I embed CalculateEveryday calculators on my own site?
- Yes, every calculator is embeddable in one line of HTML. The free embed includes a small CalculateEveryday bar and credit link; paying $5/month removes the watermark for one calculator on one site.
- What information is shown for each calculator?
- Each calculator shows the formula written out, a worked example with a realistic number, the edge cases where the result might mislead, and charts where helpful. The source and date are listed on every page.
