Triglyceride to HDL Ratio
The ratio says more about metabolic state than either number alone. High triglycerides with low HDL is the pattern that travels with insulin resistance, and the ratio captures that pairing in one figure.
Your numbers
TG / HDL
3
Triglycerides
150mg/dL
HDL
50mg/dL
What it means
3 sits in the borderline band.
Formula
TG / HDL = Triglycerides ÷ HDL
Triglycerides spike after eating. Use a value taken after 9–12 hours of fasting.

| TriglyceridesBlood triglycerides — measure after fasting or the number lies. | 150 | 20 ~ 1,000 |
| HDLThe kind that carries cholesterol back to the liver — higher is better. | 50 | 10 ~ 120 |

Frequently asked questions
Q. How is Triglyceride to HDL Ratio calculated?
TG / HDL = Triglycerides ÷ HDL — The ratio says more about metabolic state than either number alone. High triglycerides with low HDL is the pattern that travels with insulin resistance, and the ratio captures that pairing in one figure.
Q. Can you walk through an example?
With Triglycerides 150, HDL 50, the answer is TG / HDL 3.
Q. What do I need to enter?
Enter Triglycerides, HDL. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Triglycerides moves the answer to Triglycerides 75 → TG / HDL 1.5 and Triglycerides 300 → TG / HDL 6. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Triglycerides spike after eating. Use a value taken after 9–12 hours of fasting.
