Example data table
| Profile | Unit | Triglycerides | HDL | Total Cholesterol | LDL | TG / HDL Ratio | Band |
|---|---|---|---|---|---|---|---|
| Example A | mg/dL | 90 | 60 | 170 | 95 | 1.50 | Favorable |
| Example B | mg/dL | 150 | 50 | 195 | 120 | 3.00 | Monitor |
| Example C | mg/dL | 220 | 40 | 225 | 140 | 5.50 | Elevated |
| Example D | mg/dL | 320 | 35 | 255 | 155 | 9.14 | Very Elevated |
Formula used
Main ratio
TG / HDL Ratio = Triglycerides(mg/dL) ÷ HDL(mg/dL)
The tool standardizes the ratio in mg/dL. This keeps results consistent even when you type mmol/L values.
Unit conversions
Triglycerides mg/dL = Triglycerides mmol/L × 88.57
HDL mg/dL = HDL mmol/L × 38.67
Total Cholesterol or LDL mg/dL = mmol/L × 38.67
Optional support metrics
Non-HDL = Total Cholesterol − HDL
Total Cholesterol / HDL = Total Cholesterol ÷ HDL
Remnant Cholesterol = Total Cholesterol − LDL − HDL
Educational bands used here
< 2.0 = Favorable
2.0 to 3.99 = Monitor
4.0 to 5.99 = Elevated
6.0 or more = Very Elevated

Frequently asked questions
1) What does the triglyceride to HDL ratio show?
It compares triglycerides with HDL after standard conversion. Many people use it as one quick view of lipid balance, but it should be read with the full panel and personal risk factors.
2) Can I enter values in mmol/L?
Yes. The calculator accepts mg/dL and mmol/L. When you choose mmol/L, it converts values to mg/dL equivalents first, then computes the ratio so the output stays consistent.
3) Why does fasting status matter?
Triglycerides can change after meals. A non-fasting sample may raise the result, so the calculator displays a reminder. Always compare results using the same testing conditions when possible.
4) Is a lower ratio always better?
Lower often looks more favorable in simple screening tools, yet very low or changing numbers still need context. Medications, genetics, illness, and lab conditions can all affect interpretation.
5) Why include total cholesterol and LDL?
They let the page calculate non-HDL, total cholesterol to HDL, and estimated remnant cholesterol. Those extra values help you compare multiple lipid markers in one report.
6) Can this calculator diagnose heart disease or insulin resistance?
No. It is an educational calculator, not a diagnostic tool. Diagnosis depends on symptoms, history, blood pressure, medications, family history, laboratory methods, and professional assessment.
7) Why might another website give a different ratio?
Some calculators divide raw mmol/L values directly, while others convert to mg/dL first. This page standardizes the ratio after conversion, which can change the final number.
8) Should I rely on one result alone?
No. Single readings can mislead. Trend several tests, compare fasting status, and review the whole lipid panel. Discuss persistent changes with a qualified clinician.
