# Cholesterol Ratio Calculator

Calculate your cholesterol ratios (Total/HDL, LDL/HDL, Triglyceride/HDL) and assess cardiovascular risk. Get an instant risk assessment based on AHA.

## What this calculates

Cholesterol ratios provide a more comprehensive picture of cardiovascular risk than individual cholesterol numbers alone. Enter your lipid panel results to calculate key ratios and receive a risk assessment based on American Heart Association guidelines.

## Inputs

- **Total Cholesterol** (mg/dL) — min 50, max 500
- **HDL Cholesterol** (mg/dL) — min 10, max 150
- **LDL Cholesterol** (mg/dL) — min 20, max 400
- **Triglycerides** (mg/dL) — min 20, max 1000

## Outputs

- **Total/HDL Ratio** — Total cholesterol divided by HDL
- **LDL/HDL Ratio** — LDL cholesterol divided by HDL
- **Triglyceride/HDL Ratio** — Triglycerides divided by HDL
- **Risk Assessment** — formatted as text — Cardiovascular risk based on cholesterol ratios

## Details

While individual cholesterol values are important, ratios between different lipid components are stronger predictors of heart disease risk. The Total Cholesterol/HDL ratio is the most widely used: a ratio below 3.5 is considered optimal, while a ratio above 5.0 indicates elevated cardiovascular risk. The LDL/HDL ratio measures the balance between "bad" and "good" cholesterol, with values below 2.0 considered optimal. The Triglyceride/HDL ratio has emerged as a valuable marker for insulin resistance and metabolic syndrome, with values above 4.0 suggesting increased risk.

HDL cholesterol is protective because it helps remove LDL cholesterol from arteries. Desirable levels are above 40 mg/dL for men and above 50 mg/dL for women, with values above 60 mg/dL providing additional protection. LDL cholesterol below 100 mg/dL is optimal; above 160 mg/dL is considered high. Total cholesterol below 200 mg/dL is desirable, and triglycerides below 150 mg/dL are normal.

## Frequently Asked Questions

**Q: What is a good Total/HDL cholesterol ratio?**

A: A Total/HDL ratio below 3.5 is considered optimal. A ratio between 3.5 and 5.0 represents moderate risk, and above 5.0 indicates elevated cardiovascular risk. The American Heart Association uses this ratio as one indicator of heart disease risk.

**Q: Why are cholesterol ratios better than individual values?**

A: Ratios capture the balance between protective (HDL) and harmful (LDL, triglycerides) lipids. For example, a total cholesterol of 240 with an HDL of 80 (ratio 3.0) represents lower risk than a total of 200 with an HDL of 35 (ratio 5.7). Context matters more than any single number.

**Q: What does the Triglyceride/HDL ratio indicate?**

A: The Triglyceride/HDL ratio is a marker for insulin resistance and small dense LDL particles. A ratio above 4.0 suggests a higher likelihood of insulin resistance, metabolic syndrome, and the presence of small dense LDL (the most atherogenic type), even when total LDL appears normal.

**Q: How can I improve my cholesterol ratios?**

A: Regular aerobic exercise (raises HDL), eating more omega-3 fatty acids and fiber (lowers triglycerides and LDL), reducing refined carbohydrates (lowers triglycerides), maintaining a healthy weight, and quitting smoking all help improve cholesterol ratios. Medication like statins may be needed for some individuals.
