Triglyceride HDL Ratio Calculator

This tool calculates your Triglyceride-to-HDL ratio, a simple marker often used to assess cardiovascular risk and insulin resistance. It's for adults who want to better understand their lipid panel results. Units can be toggled between mg/dL and mmol/L. Everything runs securely in your browser—no data is sent online.

Understanding the Triglyceride/HDL Ratio

This ratio (Triglycerides divided by HDL Cholesterol) is a practical, calculated marker from a standard lipid panel. A higher ratio is often associated with a pattern of insulin resistance and smaller, denser LDL particles, which may increase cardiovascular risk.

How to Use This Tool

Enter your fasting Triglyceride and HDL values from your blood test.
Toggle the unit button if your results are in mmol/L (common outside the US).
Click "Calculate Ratio". The tool will compute the ratio and show a typical interpretation.
Use the "Copy Result" button to save the number for your records.

Realistic Examples

Triglycerides	HDL	Ratio	Typical Note
150 mg/dL	50 mg/dL	3.0	Moderate range
100 mg/dL	60 mg/dL	1.7	Optimal range
250 mg/dL	35 mg/dL	7.1	High range

Typical Ratio Ranges & Unit Conversions

Ratio Interpretation (General Guide)

Ratio	Typical Interpretation
< 2.0	Optimal
2.0 – 6.0	Moderate
> 6.0	High

Note: These are general wellness ranges. Clinical interpretation depends on other factors.

Unit Conversion (mg/dL ↔ mmol/L)

mg/dL	mmol/L
50	≈ 0.57
100	≈ 1.13
150	≈ 1.70
200	≈ 2.26

Conversion factor: 1 mmol/L = 88.57 mg/dL for triglycerides, 38.67 mg/dL for HDL.

Quick Non-HDL Cholesterol Helper

Non-HDL cholesterol (Total Cholesterol minus HDL) is another important risk marker. Use this helper alongside your ratio.

Total Cholesterol

HDL Cholesterol

Non-HDL Cholesterol

mg/dL (mg/dL)

Non-HDL cholesterol = Total Cholesterol – HDL. Optimal is typically < 130 mg/dL (or < 3.4 mmol/L).

Frequently Asked Questions

How accurate is this calculator?

It performs precise arithmetic using your inputs. However, the clinical significance depends on the accuracy of your lab results, fasting status, and other individual health factors.

Why does the unit toggle affect the ratio?

The ratio itself is unitless. The toggle converts your input values to a consistent unit (mg/dL) before calculation, ensuring the same numeric result regardless of which unit you enter.

When should I seek professional help?

Consult a healthcare provider if your ratio is consistently high (>6), if you have other risk factors (high blood pressure, diabetes, family history), or if you have any symptoms like chest pain or shortness of breath.

How can I improve my ratio?

Lifestyle changes like regular aerobic exercise, reducing refined sugars and carbohydrates, increasing healthy fats and fiber, and managing weight can positively impact both triglycerides and HDL. Discuss a personalized plan with your clinician.

Formulas & Assumptions

Triglyceride/HDL Ratio = Triglycerides (mg/dL) ÷ HDL Cholesterol (mg/dL).

Unit Conversion: For triglycerides: 1 mmol/L = 88.57 mg/dL. For HDL: 1 mmol/L = 38.67 mg/dL.

Non-HDL Cholesterol = Total Cholesterol – HDL Cholesterol.

All inputs are parsed accepting both comma (,) and dot (.) as decimal separators.

Results are rounded to two decimal places.

Interpretation bands are based on general public health guidance concepts.
