Estimates for general information. Not professional advice.
CalcHive publishes free calculators that run in your browser. Every result is an estimate for informational purposes. It is produced from the numbers you type and from the formulas described on that page. A result is not a quote, a bid, a diagnosis, a tax position, or a promise of what a lender, insurer, agency, or contractor will charge.
Not financial, medical, tax, or legal advice
Nothing on CalcHive is financial, medical, tax, or legal advice, and nothing on the site creates a professional relationship. Mortgage payments, loan payoff dates, rental cash flow, Social Security estimates, BMI, body-fat estimates, heart-rate zones, and nutrition figures are illustrations. Decisions about borrowing, taxes, benefits, health, or a contract belong with a qualified professional who can look at your situation.
Rules, rates, tax thresholds, and benefit formulas change. When a figure changes yearly, or is set by a government agency, use the official source rather than a number remembered from an article:
- Social Security Administration for retirement benefits and your own earnings record
- Internal Revenue Service for tax rules, including Publications 915 and 936 where those topics apply
- Consumer Financial Protection Bureau for mortgages, Loan Estimates, and home-equity credit
- Freddie Mac Primary Mortgage Market Survey for a published weekly mortgage-rate average
Nutrition and calorie estimates
The nutrition calculators estimate resting energy, a maintenance figure, gram splits, and protein amounts from the formulas named on each page. They are not a diet prescription, medical nutrition therapy, or a diagnosis. Mifflin-St Jeor estimates resting energy expenditure. It is not a measurement of the calories you burn. The activity multipliers on the TDEE page are a common convention, not an official standard. Protein figures repeat published reference amounts: the adult Recommended Dietary Allowance basis of 0.8 grams per kilogram per day, and the 2025–2030 Dietary Guidelines range of 1.2–1.6 grams per kilogram per day. They are not a target set for you. A fixed 3,500 calories per pound is not a result this site calculates. NIDDK has described why that rule overstates weight change, and points people to the Body Weight Planner instead.
The grocery list generator only scales and adds amounts you type. It does not look up prices or nutrients, and it does not convert a cup of an ingredient into ounces of that ingredient. The meal prep portion calculator divides a batch you describe. Its fridge-versus-freezer count uses the FSIS leftovers window: refrigerate within 2 hours (1 hour if the air is above 90°F), hold the refrigerator at 40°F or below, keep leftovers 3 to 4 days, and reheat to 165°F. That split is a planning count. It is not a promise that a particular dish is safe. The protein cost calculator divides a price you type by protein grams you type. It does not publish store prices. Read grams on the package or in USDA FoodData Central.
The weekly meal planner adds calories and grams you type on a seven-day grid. It does not generate recipes, look up foods, or prescribe a menu. A household multiplier on that page scales ingredient lines for a grocery list. It does not multiply the calorie totals. The household grocery budget calculator sums weekly food-plan costs you copy from USDA and applies USDA's household-size adjustment: 1 person add 20 percent, 2 add 10 percent, 3 add 5 percent, 4 no change, 5 or 6 subtract 5 percent, 7 or more subtract 10 percent. Monthly figures on that page are the adjusted weekly total times 4.333, rounded to the cent. The page does not store USDA's monthly price table. Illustration figures, when shown, are dated and are not live prices. Neither tool estimates a SNAP benefit.
When a nutrition page and an official source disagree, the official source controls. The pages cite:
- Mifflin et al., American Journal of Clinical Nutrition, 1990 (PubMed 2305711) for the resting-energy equations
- 21 CFR 101.9 for the general factors of 4, 4, and 9 calories per gram and for label calorie rounding
- Dietary Guidelines for Americans, 2025–2030 for the protein serving range and for the statement that calorie needs depend on age, sex, height, weight, and activity
- National Academies Dietary Reference Intakes for macronutrients (2002/2005) for the adult protein basis and the acceptable macronutrient distribution ranges
- NIDDK Body Weight Planner and the NIDDK explanation of the 3,500 calorie per pound rule
- USDA FSIS, Leftovers and Food Safety for the refrigerator and reheating limits used on the meal prep portion page
- USDA FoodData Central for nutrient lookups you do yourself. CalcHive does not copy those values
- USDA Food Plans monthly cost reports for household food-plan costs. The budget calculator applies the household-size footnote to weekly costs you paste. The dollar tables are not stored here as a live price list
Check the result
Before you buy materials, file a form, claim a benefit, or sign a loan, compare the calculator's output with the primary source: the product label, the lender's Loan Estimate, the agency's calculator, or a licensed professional. If a page and an official source disagree, the official source controls.
