AgeAndCalorie.com is a free calculator site built around two things most people want to know quickly and accurately: how old something is, and how many calories something has. Every tool on the site is free, requires no account, and gives you an answer in seconds.
That sounds simple. The range of what it actually covers is wider than most people expect.
What AgeAndCalorie.com Does
The site splits into two main categories — age calculators and calorie calculators — with tools that cover everything from your dog’s age in human years to the exact calorie count of your Chipotle bowl.
Here’s the full breakdown.
Age Calculators
Chronological Age Calculator
Calculates your exact age in years, months, and days from any date of birth to any target date. Not just today’s date — any date you specify, past or future. Used by speech-language pathologists, educators, and medical professionals who need the precise years;months format that standardized tests require.
👉 Chronological Age Calculator
Dog Age Calculator
Converts your dog’s age to human years using a size-adjusted formula — not the outdated 7× rule. A 10-year-old small dog and a 10-year-old Great Dane are in completely different life stages, and the calculator reflects that.
Cat Age Calculator
The same life-stage approach applied to cats. A 1-year-old cat is 15 in human years, not 7. The calculator uses AAHA guidelines and covers every stage from kitten to geriatric.
Lunar Age Calculator
Converts your Gregorian birth date to your Chinese lunar age — the traditional East Asian system where you’re born at age 1 and gain a year at Lunar New Year rather than on your birthday. Used for Chinese zodiac accuracy, the Chinese Gender Chart, and cultural traditions in China, Vietnam, and Korea.
Calorie Calculators: Restaurant Tools
Chipotle Calorie Calculator
Build your exact Chipotle order — base, protein, salsa, and extras — and see your total calories, protein, carbs, and fat in real time. Covers every ingredient on the current menu.
Subway Calorie Calculator
Select your bread, protein, cheese, sauce, and toppings for any Subway sandwich. Shows the calorie difference between 6-inch and footlong, and flags which sauce choices add the most calories.
Starbucks Calorie Calculator
Customize your Starbucks drink by size, milk type, syrup pumps, and extras. Shows how switching from whole milk to almond milk or dropping two syrup pumps changes the calorie total.
👉 Starbucks Calorie Calculator
Cava Calorie Calculator
Build your Mediterranean bowl layer by layer — base, dip, protein, toppings, and dressing. The only calculator that accounts for Cava’s full ingredient lineup including falafel, crazy feta, and tahini dressings.
Panda Express Calorie Calculator
Calculate the full nutrition for any Panda Express plate, bowl, or bigger plate. Select your side and up to three entrees to see your total.
👉 Panda Express Calorie Calculator
Taco Bell Calorie Calculator
Build any Taco Bell order — tacos, burritos, breakfast items, drinks — and calculate the total calories for your exact combination.
👉 Taco Bell Calorie Calculator
Chick-fil-A Calorie Calculator
Calculate calories for any Chick-fil-A meal including sandwiches, nuggets, waffle fries, sauces, and drinks.
👉 Chick-fil-A Calorie Calculator
Coffee Nutrition Calculator
Enter your coffee drink — espresso shots, milk type, syrup pumps — and see calories plus caffeine content. Works for homemade coffee and coffee shop orders.
Calorie Calculators: Fitness Tools
Steps to Calories Calculator
Enter your step count and body weight to see exactly how many calories your daily steps burned. More accurate than generic “100 calories per mile” estimates because it accounts for your specific weight.
👉 Steps to Calories Calculator
Treadmill Calorie Calculator
Calculate calories burned on a treadmill by entering your weight, speed, incline, and duration. Accounts for incline — the single biggest variable most treadmill displays ignore.

Why Everything on the Site Is Free
AgeAndCalorie.com doesn’t charge for any calculator, doesn’t require an account, and doesn’t ask for an email address before showing you results. The calculators exist to give people accurate information quickly — not to collect data or sell subscriptions.
The restaurant calorie calculators use official published nutrition data from each chain. The age calculators use established veterinary guidelines for pet calculators and standard date arithmetic for human age tools. The fitness calculators use MET values from published exercise science research.
Who Uses AgeAndCalorie.com
The tools get used in ways that are more varied than you’d expect:
Speech-language pathologists use the chronological age calculator to record exact ages in years;months on standardized test protocols. Getting this wrong shifts the norm table and affects scoring.
Pet owners use the dog and cat age calculators to understand what life stage their animal is actually in — which changes food choices, vet visit frequency, and what health conditions to watch for.
People tracking calories use the restaurant calculators before ordering — not after — because that’s when the information is actually useful.
People tracking their Chinese zodiac use the lunar age calculator to confirm which lunar year they were actually born in, since January and February birthdays often belong to the previous zodiac year.
Fitness trackers use the steps and treadmill calculators because most fitness devices overestimate calorie burn by 15–25% by using generic formulas that don’t account for body weight.
What Makes These Calculators Different
The gap between a good calculator and a bad one is usually one of three things: accuracy, personalization, or friction.
Accuracy: Using official restaurant nutrition data and established formulas rather than rough estimates. The Chipotle calculator uses Chipotle’s published figures for every ingredient. The dog age calculator uses size-adjusted aging models rather than the 7× rule.
Personalization: The fitness calculators use your actual body weight as an input because calorie burn scales significantly with weight. A 130 lb person and a 220 lb person walking the same route burn fundamentally different amounts — a generic estimate can’t account for that.
No friction: Every calculator on the site works immediately. No account creation. No email verification. No modal popup asking you to subscribe before showing the result. You arrive, you calculate, you leave with your answer.
