Cholesterol Ratio & LDL
TC/HDL ratio, non-HDL and Friedewald LDL from a lipid panel
Cholesterol Ratio & LDL is a free online calculator that helps you tC/HDL ratio, non. Fill in Total Cholesterol (mg/dL), HDL (mg/dL) and Triglycerides (mg/dL) and read your answer immediately. The result comes with a step-by-step breakdown — no black box, just math you can check. Use it whenever you need a reliable number without opening a spreadsheet. Everything runs in your browser — your inputs are not sent to our servers, and it works offline after the first visit (currency conversion needs a live connection).

What does the Cholesterol Ratio & LDL do?
Cholesterol Ratio & LDL works out the tc/hdl from the Total Cholesterol, HDL, and Triglycerides, following standard Health conventions — the page defaults produce a tc/hdl of 4.0 (Borderline).
- Inputs: Total Cholesterol, HDL, and Triglycerides.
- Output: the tc/hdl, plus the intermediate steps behind it.
- Method: the standard Health formula, evaluated entirely in your browser.
Quick answer
With the default inputs (total cholesterol of 200, hdl of 50, triglycerides of 150), cholesterol ratio & ldl returns a tc/hdl of 4.0 (Borderline). Assumptions and limits are summarized below.
How does it work?
Cholesterol Ratio & LDL computes the tc/hdl directly from your inputs — the Total Cholesterol, HDL, and Triglycerides feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
How the Cholesterol Ratio & LDL works
Every run of Cholesterol Ratio & LDL evaluates the Total Cholesterol, HDL, and Triglycerides you enter, applies the standard Health formula, and reports the tc/hdl with each step listed for review.
How to use it
- Total Cholesterol — used in the first stage of the calculation, so entering it accurately matters more than any later refinement.
- HDL — the value that feeds directly into the formula — match it to the scenario you are modeling before moving on.
- Triglycerides — a core input the formula applies directly — keep the units consistent with the label.
- Read the result. The tc/hdl appears immediately, with the step-by-step working underneath so you can verify every number.
- Explore. Each input change recalculates instantly; watching the tc/hdl move tells you which factor dominates your case.
The formula behind the result
Cholesterol Ratio & LDL lists every intermediate step in the result panel, so the derivation of the result can be checked line by line.
Worked example: with total cholesterol of 200, hdl of 50, triglycerides of 150, this cholesterol ratio & ldl calculation returns TC/HDL: 4.0 (Borderline).
The steps it follows:
- LDL (Friedewald) = TC − HDL − TG/5 = 200 − 50 − 30 = 120 mg/dL
Substitute your own values and the same steps produce your answer — that is the point of a calculator that shows its working.
Understanding the result
Read the tc/hdl first, then the steps: together they show not just the value but why that value follows from your inputs.
Where it helps
Students, planners, and professionals use it for planning ahead, comparing scenarios side by side, and double-checking the tc/hdl, and for sanity-checking numbers that arrived from somewhere else.
Common mistakes
Mixing up inputs with similar labels is the classic cholesterol ratio & ldl mistake; the steps panel is the quickest way to spot a value that landed in the wrong field.
Tip: Run Cholesterol Ratio & LDL twice with deliberately low and high inputs; the spread tells you how sensitive the result is, which a single run never shows.
Assumptions and limitations
Treat the tc/hdl as a planning figure rather than a binding quote, and confirm important decisions with the relevant professional.
Why use this calculator
Because the page doubles as documentation: Cholesterol Ratio & LDL puts the formula, a worked example, and the assumptions right beside the calculator.

Frequently Asked Questions
What does the Cholesterol Ratio & LDL calculate?
At its core, Cholesterol Ratio & LDL takes the Total Cholesterol, HDL, and Triglycerides and evaluates the standard formula step by step, so the figure can be checked rather than trusted on faith. Because the working is visible: Cholesterol Ratio & LDL shows each operation behind the tc/hdl in the steps panel, so you can verify the result instead of trusting a black box.
How is the tc/hdl calculated?
The first steps are ldl (friedewald) = tc − hdl − tg/5 = 200 − 50 − 30 = 120 mg/dl. Cholesterol Ratio & LDL lists every intermediate step in the result panel, so the derivation of the tc/hdl can be checked line by line.
What do I need to use the Cholesterol Ratio & LDL?
The Total Cholesterol, HDL, and Triglycerides it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the tc/hdl instantly.
What does the result from the Cholesterol Ratio & LDL mean?
The main number the cholesterol ratio & ldl returns is the tc/hdl for your exact inputs, and the supporting figures and step list give it context. Very large or very small inputs can push the tc/hdl beyond what is practically meaningful — sanity-check extreme values before relying on them.
When is the Cholesterol Ratio & LDL most useful?
Cholesterol Ratio & LDL fits planning and checking: planning ahead, comparing scenarios side by side, and double-checking the tc/hdl, or any moment when the output needs to be right the first time. On this page, cholesterol ratio & ldl applies the standard Health method to your inputs and lists every step of the working beside the result.
