Terms of Use
These terms explain how to use Our Calculator’s free calculation tools and supporting educational content, including the limits of general estimates.
Informational use
Results are provided for informational and educational purposes. Financial, tax, payroll, lending, and other real-world outcomes can depend on rules or facts that a general calculator cannot know from the inputs provided.
Check important decisions
Before acting on a material financial, tax, legal, health, or contractual decision, verify the relevant figures with the appropriate official document, institution, agency, or qualified professional.
Calculation assumptions
Each calculator page explains its model, formula, important assumptions, and known limitations. Those disclosures are part of the result and should be read when precision matters.
No professional relationship or guarantee
Using a tool does not establish an adviser, lender, accountant, or other professional relationship. Results are not offers, approvals, quotes, or promises of future outcomes. Illustrative rates are assumptions, not live market rates.
Limits of liability
To the extent permitted by applicable law, the tools and content are supplied as available without warranties of accuracy, completeness, uninterrupted access, or fitness for a particular purpose. We are not responsible for losses resulting from reliance on a general estimate or from circumstances the tool does not model. Nothing in these terms excludes rights or liabilities that applicable law does not allow to be excluded.
Responsible use and external links
Do not interfere with the service, attempt unauthorized access, or present results as a professional certification. External references are provided for context; their inclusion does not mean that their publishers endorse this site.
Availability
We may correct, update, replace, or remove tools as formulas, regulations, data, or product requirements change.
