MyFitnessPal is the app most people reach for when they decide to count calories, and its food database is genuinely hard to beat. But you should not need an account, an app install, and a subscription pitch just to learn your daily calorie target. So we built Macro Dial, a free calorie and macro calculator that runs right here in your browser. No signup, no download, no paywall. Move a few sliders and your numbers update instantly.

How to use it
Everything is a slider or a toggle, and the defaults already show a complete result. Set your age, sex, height, and weight, pick one of five activity levels, then choose whether you want to lose, maintain, or gain. If you pick lose or gain, a rate slider lets you set a daily deficit or surplus of up to 500 kcal.
Under the hood, the calculator uses the Mifflin-St Jeor equation, which estimates the calories your body burns at rest from your weight, height, age, and sex. It multiplies that by your activity level to get your maintenance calories, applies your goal, then splits the total into protein, fat, and carbs in grams. Protein is set between 1.6 and 2.2 g per kilo of body weight depending on your goal, fat sits near 28% of calories, and carbs fill the rest.
Switch between metric and imperial with the toggle at the top. Your inputs are saved on your device only, so your numbers are waiting next time. Nothing leaves your browser.
How it compares to MyFitnessPal
Let us be straight about this: a calculator does not replace food tracking. MyFitnessPal’s real value is its database of more than 14 million foods and the daily logging habit it builds around it. Knowing you need 2,100 kcal a day is step one; knowing whether you actually ate 2,100 kcal is where the results come from, and that part needs a tracker.
What our calculator does better is the starting line. MyFitnessPal asks you to create an account and walk through an onboarding flow before it shows you a calorie goal, and it estimates that goal with formulas similar to the one we use here. Macro Dial gives you the same class of estimate in about ten seconds, with zero personal data collected.
It is also worth knowing what has moved behind the paywall. In October 2022, MyFitnessPal made its barcode scanner a Premium feature, which at the time cost $19.99 a month, and long-time users were vocal about losing a tool that had been free for a decade. The free tier still covers manual food logging and the core diary. If you want the scanner, meal plans, and detailed macro goals, that is what the subscription is for.
Our suggestion: get your target here, then decide if you want an app to track against it.

If you are ready to log meals daily, MyFitnessPal remains one of the most complete food trackers on Android. The free tier handles diary logging, weight tracking, and exercise syncing without payment.
Frequently asked questions
How accurate are calorie calculators?
Formula-based calculators like this one are estimates, typically within about 10% of measured resting metabolism for most people. The Mifflin-St Jeor equation is the one dietitians most often use for this kind of estimate. Treat the number as a starting point: track your weight for two to three weeks and adjust your intake up or down based on what actually happens.
Is this the official MyFitnessPal calculator?
No. Macro Dial is an original tool built by the Unstore content team, and we are not affiliated with MyFitnessPal or its parent company in any way. We built it because a calorie target should not require an account. MyFitnessPal is named here only so you can find the real app if you want full food tracking.
Is the calculator really free, with no signup?
Yes. There is no account, no email capture, and no premium tier. Your inputs are stored in your own browser and never sent anywhere, and the page keeps working after it has loaded even if your connection drops.
Should I follow these numbers exactly?
Use them as general guidance, not medical advice. The formulas describe population averages, and they cannot account for medical conditions, medications, or a history of disordered eating. If any of those apply to you, talk to a doctor or registered dietitian before changing how you eat.
Do I still need a tracking app?
If you want results you can verify, probably yes. A target is only useful when you compare it against what you actually eat, and that is what apps like MyFitnessPal are built for. The calculator gets you the number; the tracker keeps you honest about hitting it.
