Powerlifting Calculator is operated by MAXIMI Spol. s r.o.. The calculators are free to use without registration. These notes explain their intended use and limits.
Using the tools
Use the calculators to perform arithmetic, compare results under a specified formula and prepare training or competition worksheets. Check the selected units and inputs before relying on an output. Do not interfere with the website or misuse its contact form.
Calculation and training disclaimer
Outputs are informational references. They do not determine official placings, qualification, equipment compliance or eligibility. Formula versions, coefficient tables, federation rules and rounding conventions can differ or change. The methodology identifies known limitations, including inherited tables that have not been fully verified.
The tools do not assess your health, readiness or ability to lift a weight. A percentage or proposed attempt is not an individual training prescription. Make training decisions appropriate to your circumstances and obtain qualified assistance when needed.
Errors and availability
Errors and interruptions are possible. For a competition-critical decision, verify the result with the event organiser and applicable rules. Please report reproducible errors with the selected settings and an authoritative source.
External links and support
Federation names and source links identify references; they do not imply endorsement. Optional support through Ko-fi is handled by that external service and is not required to use a calculator. Review the destination’s terms before making a contribution.
Privacy and contact
Shared calculator links expose the values in their URL. Avoid private athlete information. Read the Privacy Policy and cookie and browser-storage information. Questions: contact@powerlifting-calculator.com.
