Cholesterol Ratio Calculator

Your details

The total cholesterol figure from your lipid panel.
mg/dL
High-density lipoprotein, the "good" cholesterol.
mg/dL
Fasting triglycerides from your panel. Needed for the TG/HDL ratio and to estimate LDL.
mg/dL
Leave at 0 (blank) to estimate LDL from total, HDL and triglycerides using the Friedewald equation. That estimate is only valid up to 400 mg/dL (4.5 mmol/L) of triglycerides, so above that you need a directly measured LDL.

Your total-to-HDL ratio is 4:1, acceptable but worth improving.

  • Non-HDL cholesterol, everything except the "good" HDL, is 150 mg/dL; it captures all the cholesterol-carrying particles that drive plaque.
  • Your LDL/HDL ratio is 2.4:1 (acceptable); aim below 2.0 to keep "bad" cholesterol well in check.
  • Your triglyceride/HDL ratio is 3:1 (borderline), a marker often linked to insulin resistance and small, dense LDL particles.
  • Raising HDL (exercise, not smoking) and lowering total cholesterol and triglycerides all pull these ratios down at once.

Next stepKeep up heart-healthy habits and recheck your lipids as your doctor recommends.
