Health Calculators

Explore our wide collection of online health calculators designed to help you assess key wellness parameters. From blood pressure and heart rate to nicotine score and intravenous fluid rates, these tools support everyday health management, fitness planning, and medical monitoring.

Urine Albumin-Creatinine Ratio (UACR)

This calculator helps assess kidney function by calculating the urine albumin-to-creatinine ratio (UACR). It’s a standard test for detecting early kidney damage, especially in individuals with diabetes or hypertension.

Total Parenteral Nutrition (TPN)

This calculator helps determine the total nutritional needs of patients requiring parenteral (IV) nutrition. It estimates Basal Energy Expenditure (BEE), Ideal Body Weight (IBW), macronutrient distribution (lipids, dextrose, protein), nitrogen balance, and the non-protein calorie-to-nitrogen ratio.

Systemic Vascular Resistance (SVR)

This calculator estimates Systemic Vascular Resistance (SVR), a key measure of afterload and vascular tone. It uses mean arterial pressure (MAP), central venous pressure (CVP), and cardiac output (CO) to assess blood flow resistance within systemic circulation.

Specific Absorption Rate (SAR)

This calculator determines the Specific Absorption Rate (SAR), which measures the rate at which the body absorbs energy from an electromagnetic field. It's primarily used to evaluate radiation exposure from devices like mobile phones.

Resting Metabolic Rate (RMR)

This calculator estimates your Resting Metabolic Rate (RMR) — the number of calories your body needs at rest to maintain vital functions like breathing, circulation, and cell production. It's based on weight, height, age, and gender using the Mifflin-St Jeor equation.

Nicotine Level

This calculator estimates your daily nicotine intake based on the number of cigarettes you smoke and the average nicotine content per cigarette. It's a helpful tool for smokers to understand their nicotine exposure and consider reduction strategies.

Mifflin-St Jeor BMR

This calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor Equation. It provides the number of calories your body needs at rest based on your age, gender, weight, and height—essential for weight management and nutrition planning.

Karvonen Heart Rate

This calculator estimates your target heart rate for exercise using the Karvonen formula. It considers your age, resting heart rate, intensity percentage, and gender to calculate personalized training zones for optimal cardiovascular performance.

IV Flow Rate

This calculator determines the intravenous fluid flow rate based on the total volume to be infused, infusion time, and a flow factor. It’s a valuable tool for healthcare providers to ensure accurate and consistent fluid administration.

IV Drip Rate

This calculator helps determine the appropriate drip rate for intravenous fluid administration. Based on the volume to be infused, drop factor, and duration, it calculates the required drops per minute for accurate manual IV delivery.

Blood Type Inheritance

This calculator determines possible parent blood groups based on a child's blood type. It helps explore the genetic inheritance patterns of ABO and Rh blood groups between parents and offspring.

Heart Rate Calorie Burn

This calculator estimates how many calories you burn during exercise based on your heart rate, weight, age, duration, and gender. It provides a personalized calculation using scientifically validated formulas for males and females.

Heart Beats Since Birth

This calculator estimates how many times your heart has beaten since you were born. Based on your birth date and average resting heart rate, it provides a fun and fascinating insight into your body's lifelong activity.

E-Juice Mixing

This calculator helps you mix your own e-liquid by calculating the exact amounts of nicotine base, PG, VG, and flavoring needed. Enter your desired nicotine strength, target volume, and flavor percentage to get a customized e-juice recipe.

Hardy-Weinberg Equilibrium

This genetics calculator determines allele frequencies and expected genotype frequencies under Hardy-Weinberg equilibrium. It also calculates the chi-square statistic to test whether a population is in genetic equilibrium.

IV Drops Per Minute

This calculator determines the required number of IV drops per minute for fluid administration. Based on the total volume, drop factor, and time, it helps ensure accurate infusion rates during intravenous therapy.

Type 2 Diabetes Insulin Level

This calculator estimates insulin level requirements for individuals with Type 2 Diabetes Mellitus. By inputting your weight, height, fasting blood glucose (FBG), and an adjustment factor, it provides a personalized estimate to support diabetic health monitoring.

Breath Counter Since Birth

This fun health calculator estimates how many breaths you have taken since the day you were born. Simply enter your birth date, and the tool will calculate your total number of breaths based on an average respiration rate.

Cockcroft-Gault Creatinine

This calculator estimates creatinine clearance (CrCl) using the Cockcroft-Gault equation. It helps assess kidney function based on age, weight, serum creatinine, and gender, making it a valuable tool in medication dosing and renal function monitoring.

Cigarette Expense

This calculator helps you estimate how much money you spend on smoking daily, monthly, and yearly. By understanding the financial impact of your smoking habit, you can take steps to reduce or quit for both your health and your wallet.

BUN to Creatinine Ratio

This calculator determines the ratio between Blood Urea Nitrogen (BUN) and serum creatinine levels. It's a valuable diagnostic tool used to assess kidney function and identify the underlying cause of acute kidney injury.

Bruce Protocol VO₂ Max

This calculator estimates VO₂ max using the Bruce Protocol treadmill stress test. It measures cardiovascular endurance based on exercise duration and provides an approximation of oxygen uptake (mL/kg/min), helping athletes and clinicians evaluate heart and lung fitness.

Blood Pressure Range

This calculator helps you assess your blood pressure levels by entering systolic and diastolic values. It determines whether your blood pressure is normal, elevated, or within hypertensive stages, offering a quick and easy way to monitor cardiovascular health.

Arterial Blood Gas

This medical calculator helps you analyze Arterial Blood Gas (ABG) values for a better understanding of a patient’s respiratory and metabolic status. It interprets pH, PaCO₂, and HCO₃⁻ levels to determine the type of acid-base disturbance and compensation status.

Blood Alcohol Content (BAC)

This calculator estimates your Blood Alcohol Content (BAC) or Blood Alcohol Level (BAL) based on your weight, gender, the number of drinks consumed, and the time elapsed. It helps you understand your level of intoxication and potential impairment after alcohol consumption.
