Results are estimates. Always verify important decisions with a qualified professional or official source. Using this Site does not create an advisory relationship.
1. General disclaimer
The website www.usacalc.online (“USACalc,” “we,” “us”) provides free online calculators, guides, and related content for informational and educational purposes only.
By using this Site you acknowledge that:
- Results are estimates based on the inputs you provide and the formulas we implement
- We do not guarantee accuracy, completeness, or suitability for your specific situation
- You use the Site and any results at your own risk
2. Not financial or investment advice
Mortgage, loan, APR, interest, amortization, debt payoff, savings, retirement, 401(k), HELOC, and similar calculators produce illustrative estimates only. Actual rates, fees, taxes, insurance, and approval terms depend on lenders, your credit, and market conditions.
USACalc is not a lender, broker, or financial advisor. Do not make borrowing or investing decisions based solely on our tools. Consult a licensed professional when needed.
3. Not tax advice
Federal income tax, tax refund, paycheck, sales tax, and related calculators use simplified assumptions and published rates that may change. They do not account for every deduction, credit, state rule, or filing situation.
- Tax law changes frequently
- Your actual liability may differ
- We are not a CPA, enrolled agent, or tax attorney
For filing or planning, rely on official IRS guidance, state tax agencies, or a qualified tax professional.
4. Not medical or health advice
BMI, body fat, calorie, BMR/TDEE, macro, age, ovulation, pregnancy, due date, pet age, and similar calculators are educational estimates. They are not a diagnosis, treatment plan, or substitute for care from a licensed clinician.
Body composition methods (including the US Navy circumference formula) have known margins of error. Pregnancy and ovulation estimates assume typical cycles and are not a guarantee of fertility or due date. Always follow medical advice from your doctor or midwife for health and pregnancy decisions.
5. Not legal or academic advice
GPA and education-related tools follow common U.S.-style 4.0 weighting for illustration. Schools and countries use different scales and conversion rules. Official transcripts and institutional policies control. We do not provide legal advice of any kind.
6. No warranty
The Site and all calculators are provided “as is” and “as available.” We make no warranties — express or implied — about uninterrupted access, freedom from errors, or fitness for a particular purpose. Formulas and published parameters may lag real-world updates.
7. Limitation of liability
To the fullest extent allowed by law, USACalc and its operators are not liable for any loss or damage arising from:
- Use of or reliance on calculator results or articles
- Errors, omissions, or outdated information
- Decisions about money, health, education, or legal matters
- Third-party ads, links, or external websites
Full legal terms are in our Terms and Conditions.
8. Third-party content and ads
The Site may display advertisements and link to external resources. We do not control third-party content, products, or privacy practices. Visiting external sites or interacting with ads is at your own risk.
9. Your responsibility
