Cholesterol Ratio Calculator

Our Cholesterol Ratio Calculator helps estimate LDL/HDL, triglycerides/HDL, and total cholesterol/HDL ratios based on your medical test results.

How the Calculator Works

Input the required values to calculate your cholesterol ratios:

Enter Total Cholesterol.
Enter HDL and LDL values.
Triglycerides value is optional.
Select your gender.
Click the "Calculate" button.

Output:

Total Cholesterol/HDL (TC/HDL) ratio
LDL/HDL ratio
Cholesterol level
Optimal and high-risk limits
Triglyceride level (if provided)

Types of Cholesterol

LDL (Low-Density Lipoprotein) Cholesterol

LDL is considered "bad cholesterol" due to its lower protein content. Excess LDL can accumulate as plaque in the arteries, restricting blood flow. You can monitor LDL using the LDL/HDL ratio calculator.

HDL (High-Density Lipoprotein) Cholesterol

HDL is "good cholesterol" because it has a higher protein content. It helps maintain healthy blood flow and prevents artery blockage. Cholesterol/HDL ratio charts provide insights into HDL levels based on age.

Cholesterol Ratio Risk Chart

Total Cholesterol / HDL		LDL / HDL		Risk Level
Male	Female	Male	Female	Risk Level
<3.4	<3.3	<1.1	<1.5	A very low risk
3.5 – 4.4	3.4 – 4.1	-	-	Low risk
4.5 – 7.2	4.2 – 5.7	1.2 – 4.9	1.6 – 4.1	Average risk
7.2 – 16.5	5.8 – 9	5 – 7.1	4.2 – 5.5	Moderate risk
>16.6	>9.1	>7.2	>5.6	High risk

Triglycerides

Triglycerides are another type of fat in your blood. High levels can increase the risk of heart disease. Including triglyceride values in the cholesterol ratio calculation can provide additional insight into your cardiovascular risk.

Triglycerides and Cholesterol Ratios

Triglycerides are a type of fat found in the blood. They are stored in fat cells and used by the body to release energy when needed. The HDL/Triglycerides ratio calculator helps evaluate the balance between “good cholesterol” and triglycerides for cardiovascular health.

Cholesterol Ratio Chart

This chart helps assess cholesterol levels and the risk for coronary artery disease:

Parameter	Desirable	Borderline High	High
Total Cholesterol (mg/dL)	Less than 200	200–239	240 and above
HDL Cholesterol (mg/dL)	60 and above	40–59	Less than 40
LDL Cholesterol (mg/dL)	Less than 130	130–159	160 and above
Triglycerides (mg/dL)	Less than 150	150–199	200 and above
LDL/HDL Ratio	2.0 or lower	Below 5.0	Above 5.0
Triglycerides/HDL Ratio	2.0 or lower	4.0	Above 6.0
Total Cholesterol/HDL Ratio	Below 0.87	1.74–2.62	Above 2.62

Triglycerides are primarily consumed when your body is in a calorie deficit. Online tools like the Calorie Deficit Calculator can help determine your energy requirements.

Normal Range of Triglycerides

A simple blood test can determine whether your triglyceride levels fall into a healthy range. The ranges are:

Normal: Less than 150 mg/dL (1.7 mmol/L)
Borderline High: 150–199 mg/dL (1.8–2.2 mmol/L)
High: 200–499 mg/dL (2.3–5.6 mmol/L)
Very High: 500 mg/dL or above (5.7 mmol/L or above)

Triglycerides to HDL Ratio

The Triglycerides to HDL ratio calculator simplifies the evaluation of cardiovascular risk. Doctors often measure triglycerides alongside cholesterol tests. The cholesterol ratio calculator provides insight into HDL and LDL levels, helping ensure proper blood flow and reducing heart disease risk.

How to Calculate Total Cholesterol Without a Calculator

Example: If Total Cholesterol (TC) = 3 mg/dL, HDL = 5 mg/dL, LDL = 5 mg/dL:

TC/HDL Ratio: 3 ÷ 5 = 0.6 → Very low risk of cardiovascular disease
LDL/HDL Ratio: 5 ÷ 5 = 1 → Very low risk
Total Cholesterol: 3 mg/dL → Optimal
HDL: 5 mg/dL → High risk
LDL: 5 mg/dL → Optimal
Triglycerides: -35 mg/dL → Invalid/Check lab values

The Triglycerides/HDL ratio calculator provides important insight into HDL/LDL balance and associated cardiovascular risk.

Consequences of High Cholesterol

Excess cholesterol can lead to serious, potentially life-threatening diseases:

Coronary artery disease
Stroke
Peripheral artery disease
Chronic kidney failure

How to Lower Cholesterol

To maintain healthy cholesterol levels, consider these strategies:

Engage in regular physical activity
Maintain a balanced, heart-healthy diet
Take medications as prescribed by a healthcare provider

FAQs

How to Calculate Cholesterol Ratio? (Example)

If Total Cholesterol = 274 mg/dL and HDL = 61 mg/dL:

Cholesterol Ratio = Total Cholesterol ÷ HDL = 274 ÷ 61 = 4.49 mg/dL

What Does mmol/L Stand For?

mmol/L means millimoles per liter. It is another unit for measuring HDL, LDL, and total cholesterol. To calculate cholesterol ratio in mmol/L:

Cholesterol Ratio (mmol/L) = Total Cholesterol (mmol/L) ÷ HDL (mmol/L)

Can Cholesterol Ratio Be Too Low?

Yes, a low cholesterol ratio is generally good and common in athletes. However, extremely low ratios may indicate thyroid disease, metabolic disorders, or genetic conditions.
