Use our free Heart Rate Calculator to find your maximum heart rate (MHR) and personalised training zones (1–5) based on your age. This tool is designed for adults aged 19–100 and supports both the standard percentage of max HR method and the Karvonen (HRR) method using resting heart rate. Whether you’re aiming for fat burning, endurance, or high-intensity training, our calculator gives you instant results.
Q: How do I calculate my maximum heart rate?
A: The most common formula is 220 – age, but more accurate methods include Tanaka (208 – 0.7×age) and HUNT (211 – 0.64×age). Our calculator lets you choose.
Q: What is the best heart rate zone for fat burning?
A: Zone 2 (60–70%) is widely considered best for fat burning and endurance.
Q: Can I use this if I’m under 19?
A: No. This tool is for adults aged 19+. Younger athletes should consult a coach or healthcare professional.
Q: What is the Karvonen HRR method?
A: It uses resting heart rate to calculate more personalised training zones: Target HR = Resting HR + (MHR – Resting HR) × % intensity.
Q: Is this calculator safe for medical use?
A: No. It’s a fitness guidance tool only. Always consult your doctor before beginning a new exercise program, especially if you have health conditions.
