Overweight Calculator – How Many Kilograms Above Healthy Weight
See whether you are overweight and how many kilograms above a healthy weight (BMI 24.9) you are, with the estimated time to reach it.
Tip: Losing just 5–10% of your current weight already significantly lowers blood pressure, blood sugar and the load on the joints.

About this digital tool
According to the World Health Organization, overweight starts when BMI reaches 25, while obesity starts at 30 and above. This calculator doesn't stop at the category: it shows you exactly how many kilograms you are above the upper limit of a healthy weight (BMI 24.9 for your height) and what percentage of your current weight this excess represents.
For practical purposes, it also gives an approximate timeframe: with steady loss of 0.5 kg or 1 kg a week. The pace doctors recommend is 0.5–1 kg/week; very fast loss usually comes back and loses muscle. Use the result as a guide, not as a diagnosis.
How to use
- Enter your current weight in kg
- Enter your height in cm
- See the category by BMI
- Read how many kg you are above the maximum healthy weight
- Compare the timeframes for a loss of 0.5 kg or 1 kg a week and choose a realistic pace
Frequently asked questions
How do I know if I'm overweight?
Calculate BMI = weight (kg) ÷ height² (m). If it comes to 25–29.9 you are overweight; 30–34.9 class I obesity; 35–39.9 class II; above 40 class III.
How many kilograms can I lose per week safely?
Usually 0.5–1 kg a week, with a deficit of about 500–1000 kcal a day. Faster loss raises the risk of losing muscle and regaining weight.
Can I have a high BMI without being unhealthy?
Yes — BMI doesn't distinguish muscle from fat, so athletes with high muscle mass can come out 'overweight'. Waist circumference and body fat percentage give a fuller picture.
What weight is healthy for my height?
The BMI range of 18.5–24.9. The calculator shows you the upper limit in kg; for the full range use the healthy weight calculator.
Does this tool replace medical advice?
No. It is an estimate. For a weight-loss plan, especially with other illnesses or medication, talk to a doctor or dietitian.
