Estimates only

Our calculators use standard formulas and the values you enter. Real-world outcomes can differ because of factors a calculator cannot know. Common reasons a result may not match your situation include:

• An input that was mistyped, entered in the wrong unit or estimated rather than measured.
• Rounding — results are rounded for display, and other tools may round at different steps.
• Simplifying assumptions built into the formula, such as a fixed interest rate or an average body composition.
• Rules that vary by country, state, institution or provider.

The information on this site is provided for general educational purposes and in good faith, but we make no guarantee of its completeness, accuracy or suitability for your circumstances.

Financial calculators

Loan, mortgage, auto loan, interest, compound interest, tip and discount results are estimates. In particular:

• The mortgage calculator shows principal and interest; it does not include property taxes, homeowners insurance, mortgage insurance or HOA fees unless stated.
• Loan results do not include origination fees, closing costs, late fees or prepayment penalties.
• Results assume a fixed rate and on-time payments for the whole term. Variable-rate loans, promotional rates and missed payments change the outcome.
• Compound interest projections assume a constant rate of return, which real investments do not deliver.

Your actual rate, payment and costs are set by your lender or financial institution. This is not financial, investment or tax advice.

Health calculators

BMI, calorie, BMR, body fat and ideal weight results are population-based estimates and do not account for individual medical conditions.

• BMI does not distinguish muscle from fat and may misclassify athletes, older adults and some ethnic groups. Its standard categories apply to adults, not children or teens.
• Calorie and BMR equations can differ from your measured metabolism by a meaningful margin.
• Tape-measure body fat methods are sensitive to small measuring errors.
• These tools are not designed for pregnancy, breastfeeding, eating disorders or medically supervised diets.

They are not medical advice. Consult a doctor or registered dietitian before changing your diet, exercise or weight goals.

Date and time calculators

Date results use the Gregorian calendar. Weekday counts include Monday through Friday and do not exclude public holidays, which vary by location. Time-of-day calculations do not account for time zones or daylight saving time changes. For legal, contractual or payroll deadlines, confirm the counting rules that apply to you.

Education calculators

The GPA calculator uses the common 4.0 scale with standard plus and minus values. Schools differ in how they weight grades, treat honors or AP courses and round results, so your official GPA is the one on your transcript. Grade calculator results depend on the weights in your course syllabus.

Construction and measurement

Material estimates are approximations. Actual quantities depend on site conditions, forms, compaction and spillage, so add an appropriate waste allowance. Bag yields vary by product. Confirm quantities with your supplier or contractor, and follow local building codes and safety requirements.

Conversions and math

Unit conversions use exact definitions, but displayed results are rounded. Math and scientific results are computed with standard floating-point arithmetic, which can produce tiny rounding differences in the last decimal places. For engineering, scientific or safety-critical work, verify results with an appropriate professional tool.
