Terms of Use
CalculatorToolBase provides free calculators and converters for general informational use.
No professional advice
Results are arithmetic outputs or general estimates only. They do not replace professional advice and should not be used for high-stakes medical, legal, tax, investment, loan, mortgage, insurance, or safety decisions.
Accuracy
We aim to keep formulas clear, but users are responsible for checking inputs, assumptions, units, local requirements, product labels, and whether a calculator fits their situation.
Acceptable use
Use the site for ordinary calculator and converter tasks. Do not attempt to disrupt the service, scrape it in a way that harms availability, bypass consent controls, misrepresent calculator outputs as certified professional advice, or use the tools for decisions that require qualified professional review.
Advertising
The site may display labelled advertising. Ads must not be treated as calculator results, recommendations, professional advice, or endorsements by CalculatorToolBase.
Availability
CalculatorToolBase may change, add, remove, or update calculators and pages over time. The site may also be unavailable during hosting issues, maintenance, or third-party service interruptions.
Corrections
Formula corrections, broken links, and content concerns can be sent through the contact page.
