Fat Burn Heart Rate Calculator

If you're serious about burning fat, knowing your fat-burning heart rate zone is the secret sauce you might be missing. Whether you're walking, running, cycling, or doing HIIT, being in the right heart rate zone helps your body target fat as the primary fuel source. Our Fat Burn Heart Rate Calculator is designed to make this process simple and accurate based on your age, gender, and resting heart rate. No guesswork, just results.

What Is the Fat-Burning Heart Rate Zone?

The fat-burning zone is the heart rate range in which your body burns a higher percentage of fat compared to carbohydrates. Typically, this is around 60% to 75% of your maximum heart rate (MHR). While higher intensities burn more total calories, staying in this zone helps the body focus more on burning fat.

For example:

• A 30-year-old person has an approximate MHR of 190 bpm.
• 65% of that is 123 bpm, and 75% is 143 bpm.
• So, their fat-burning heart rate range is 123 to 143 bpm.

How Is Fat Burn Heart Rate Calculated?

There are several methods to calculate fat-burning heart rate. Our tool supports the three most accurate formulas:

1. Karvonen Formula (Most Personalized)

Target HR = ((MHR − RHR) × Intensity) + RHR

2. Tanaka Formula (General Use)

MHR = 208 − (0.7 × Age)

3. Gulati Formula (More Accurate for Women)

MHR = 206 − (0.88 × Age) (for females)

Once your MHR is calculated, the calculator estimates:

• Fat Burn Zone: 60%–75% of your MHR
• Cardio Zone: 75%–85%
• Peak Zone: 85%–95%

How to Use the Fat Burn Heart Rate Calculator

1. Enter your age – This helps calculate your MHR accurately.
2. Select your gender – For better precision, especially for females using the Gulati formula.
3. Input your resting heart rate (RHR) – The Karvonen formula considers this for personalization.
4. Choose a formula – Pick between Karvonen, Tanaka, or Gulati.
5. Set intensity range – Default is 65%–75%, ideal for fat-burning.
6. Click Calculate – You’ll get your fat-burning heart rate range instantly.

You’ll also see your warm-up, cardio, and peak zones to guide your entire workout.

Is It Effective to Stay in the Fat-Burning Zone?

Absolutely. Staying in the fat-burning zone for 30 to 60 minutes a day helps your body become efficient at oxidizing fat for fuel. However, mixing in cardio and peak zones weekly can maximize total calorie burn and improve heart health.

Many people ask:

"Will 30 minutes of cardio a day burn fat?"

Yes, especially if you're within your fat-burning heart rate zone.
