Quick Answer
How Do You Read a Weight Loss Percentage Chart?
Find your starting weight down the left, slide across to the pounds you have lost along the top, and the cell where they meet is your percentage. A 200 lb start with 20 lb lost reads 10.0%. The chart is nothing more than the formula ((pounds lost ÷ starting weight) × 100) pre-calculated for common weights — and the embedded calculator handles any figure the chart does not list, in kg, lb or stone.
Weight Loss Percentage Reference Chart
Read the chart by picking the row closest to your starting weight and the column matching how many pounds you have lost. Each cell is the pounds lost divided by that starting weight, expressed as a percentage. Notice how the same pounds lost is worth a bigger percentage at a lighter starting weight — 20 lb is 13.3% of 150 lb but only 6.7% of 300 lb — which is exactly why percentage, not pounds, is the fairer measure of progress.
| Starting Weight ↓ / Lost → | 5 lb | 10 lb | 15 lb | 20 lb | 25 lb |
|---|---|---|---|---|---|
| 150 lb | 3.3% | 6.7% | 10.0% | 13.3% | 16.7% |
| 180 lb | 2.8% | 5.6% | 8.3% | 11.1% | 13.9% |
| 200 lb | 2.5% | 5.0% | 7.5% | 10.0% | 12.5% |
| 220 lb | 2.3% | 4.5% | 6.8% | 9.1% | 11.4% |
| 250 lb | 2.0% | 4.0% | 6.0% | 8.0% | 10.0% |
| 300 lb | 1.7% | 3.3% | 5.0% | 6.7% | 8.3% |
Every cell = (pounds lost ÷ starting weight) × 100, rounded to one decimal place.
Weight Loss Percentage Chart in Kilograms
| Starting Weight ↓ / Lost → | 3 kg | 5 kg | 8 kg | 10 kg | 12 kg |
|---|---|---|---|---|---|
| 60 kg | 5.0% | 8.3% | 13.3% | 16.7% | 20.0% |
| 70 kg | 4.3% | 7.1% | 11.4% | 14.3% | 17.1% |
| 80 kg | 3.8% | 6.3% | 10.0% | 12.5% | 15.0% |
| 90 kg | 3.3% | 5.6% | 8.9% | 11.1% | 13.3% |
| 100 kg | 3.0% | 5.0% | 8.0% | 10.0% | 12.0% |
| 120 kg | 2.5% | 4.2% | 6.7% | 8.3% | 10.0% |
Every cell = (kilograms lost ÷ starting weight) × 100, rounded to one decimal place.
Calculate the Exact Figure
The chart rounds to tidy rows, but your own numbers rarely land on them. To get the precise figure, divide the pounds you have lost by your starting weight and multiply by 100 — a 235 lb start with 12 lb lost is 12 ÷ 235 × 100, or 5.1%. Rather than reach for a calculator, enter your starting and current weight into the Weight Loss Percentage Calculator embedded above and it returns the exact percentage, along with your rate per week if you add the time elapsed. Pairing that figure with your BMI shows whether the progress has moved you into a different weight band.
What the Milestones Mean
Certain columns on the chart line up with figures that appear in weight management research. The modest-weight-loss literature reports the first measurable metabolic changes in the 3–5% range (Wing et al., 2011), with further benefit documented as the figure climbs toward 10%. On the chart, a 250 lb start crosses 5% near 12.5 lb lost and 10% at 25 lb. Those are checkpoints to read off, not targets prescribed to anyone. To turn a target percentage into a projected date, the Goal Weight Calculator runs the timeline from your own weight.
