Estimates Only — Not Advice
Everything on ToolsZio is provided for general information and education only. Calculators and tools give estimates based on the numbers you enter and on the formulas stated on each page. Nothing on this site is financial advice, tax advice, legal advice, or medical advice, and nothing here creates a professional relationship between you and ToolsZio or its owner.
Finance Calculators
Mortgage, loan, affordability, retirement, savings and other finance results are planning estimates. They do not know your credit score, your income history, your local property taxes, your lender's fees, or current interest rates offered to you. Actual payments, approvals and rates depend on your lender and your circumstances. Tax figures and contribution limits change every year — check the current figures with the IRS or a qualified tax professional before acting. Before borrowing, investing, or making a large purchase, talk to a licensed financial adviser or your lender.
Health Calculators
BMI, calorie, body fat and pregnancy calculators give general information based on standard formulas. They do not diagnose, treat, or assess any individual. Bodies differ, and a formula cannot know your medical history, medications, or pregnancy details. If you have a medical condition, are pregnant, or are planning changes to diet, exercise or medication, talk to a qualified health professional first.
Accuracy
We work to keep formulas and figures correct, but we do not guarantee that any result is accurate, complete or up to date. Interest rates, tax tables, contribution limits, time-zone rules and daylight saving dates change over time. Each tool page states its assumptions — read them, and verify important figures with an authoritative source before relying on them.
Your Responsibility
You are responsible for the numbers you enter and for any decision you make based on a result. ToolsZio is not liable for losses, costs or other consequences arising from reliance on an estimate. If a result affects a significant decision — a mortgage, a loan, an investment, a medical choice — get a second opinion from a qualified professional.

If you believe a calculator is wrong, please tell us through the contact page with the inputs you used, so we can check it and fix it.
