Medical Calculators

This section runs in two directions at once. One set of tools measures the patient — surface area, dosage, oxygen flow, incidence and attack rates. The other set measures the practice — what a treatment, a patient or an X-ray costs to deliver. Both matter, and keeping them in one section makes the clinical and the financial sides of care easy to find together.

A net collection rate tells a medical practice how much of the money it was actually owed ever arrived.

A service line can look busy and still lose money on every patient it treats.

A capitation rate calculator shows what a health plan pays a provider for each enrolled member each month, known as the per-member-per-month (PMPM) rate.

A prescribed dose is only half the job.

Oxygen flow rate is the volume of oxygen delivered to a patient each minute, measured in liters per minute (L/min).

An incidence rate answers one narrow question: how many new cases appeared in a population that could have had them, scaled to a standard 100,000 people so places of different sizes can be compared fairly.

Every X-ray a department performs carries a slice of the equipment, the technologist time, the consumables, and the overhead.

After a wedding, a training course, or a shared meal, one number tells you how hard an outbreak hit the group that was actually exposed: the attack rate.

Two clinics can quote you $8,000 and $9,600 for what sounds like the same smile, and the totals tell you almost nothing until you divide by the number of teeth.
