Calculate mortality rate online with our easy Mortality Rate Calculator. Find death rate, crude mortality rate, ratio, and percentage in seconds.
A Mortality Rate Calculator helps you find the death rate in a group or population. It uses the number of deaths and the total population. The result can show deaths per 1,000, 10,000, 100,000, or 1,000,000 people, which is a measure of the Crude Death Rate.
Our online death rate calculator makes this process fast and simple. You only need the number of deaths, the mid-year population, and your preferred rate scale. The tool then gives the mortality rate, ratio, and percentage.
Mortality data can help in public health, medical research, insurance, and risk analysis, including determining the Time Of Death. It can also help users understand crude mortality rates and population death trends.
The basic mortality rate calculation formula is:
Mortality Rate = (Number of Deaths ÷ Mid-Year Population) × Multiplier
For the standard crude mortality rate:
Crude Mortality Rate = (Number of Deaths ÷ Mid-Year Population) × 1,000
The multiplier sets the rate scale. A value of 1,000 gives deaths per 1,000 people. A value of 100,000 gives deaths per 100,000 people.
The calculator also finds the mortality percentage:
Mortality Percentage = (Number of Deaths ÷ Population) × 100
For example, if 500 people die in a population of 100,000:
Mortality Rate = (500 ÷ 100,000) × 1,000
Mortality Rate = 5 deaths per 1,000 people.
Mortality Percentage = (500 ÷ 100,000) × 100
Mortality Percentage = 0.5%.
Enter the total number of deaths for the period you want to study. Use a value of zero or greater.
Enter the population for the same area and period. The calculator uses this value as the main denominator.
Choose the rate scale you need. You can use 1,000, 10,000, 100,000, or 1,000,000.
Enter the time period, such as 1 year. This helps describe the data. In this calculator, the period does not change the mathematical result.
Click the calculate button. The tool finds the mortality ratio, mortality rate, and mortality percentage.
Suppose a town has 100,000 people. During one year, 500 deaths occur.
Use the mortality rate formula:
Mortality Rate = (Deaths ÷ Population) × 1,000
Mortality Rate = (500 ÷ 100,000) × 1,000
Mortality Rate = 0.005 × 1,000
Mortality Rate = 5 deaths per 1,000 population.
The mortality percentage is:
Mortality Percentage = (500 ÷ 100,000) × 100
Mortality Percentage = 0.5%.
So, the final result is 5 deaths per 1,000 people, or 0.5%.
A crude mortality rate calculator uses the total population as the denominator. A cause-specific mortality rate calculator focuses on deaths from one cause. An age-specific mortality rate calculator uses a particular age group.
An infant mortality rate calculator uses infant deaths and live births. It is not the same as the general mortality rate.
A fatality rate calculator is also different. It measures deaths among people who have a specific disease or condition. A survival rate calculator measures the share of people who remain alive after a given period.
Terms such as burn mortality rate, expected mortality rate, and mortality risk score may use special clinical methods. They should not be calculated with the basic crude mortality formula unless the method specifically calls for it.
The Mortality Rate Calculator offers a quick way to calculate a basic death rate. Its main formula is simple:
Mortality Rate = (Number of Deaths ÷ Mid-Year Population) × Multiplier
For the standard crude mortality rate, use 1,000 as the multiplier. The result is then shown as deaths per 1,000 population.
Keep in mind that mortality rates can vary by age, cause, disease, location, and time. A simple mortality rate also cannot predict an individual's lifespan. Questions about life expectancy, mortality prediction models, or mortality risk scores need different data and methods.
Divide the number of deaths by the mid-year population. Then multiply the result by the chosen multiplier. For a standard crude mortality rate, use 1,000.
Life expectancy isn't calculated from a basic mortality rate alone. It normally uses age-specific mortality data and life-table methods. Individual life expectancy also depends on many factors.
A basic mortality rate calculator cannot give this probability. The estimate requires age-specific survival or mortality data for the relevant population.
A 95% mortality rate means that 95 out of every 100 people in the defined group would die during the specified measurement period. The exact meaning depends on the population, disease, time period, and definition used.
No. Mortality rate usually describes deaths in a population. Fatality rate describes deaths among people affected by a particular disease or condition.
A crude mortality rate is the total number of deaths relative to the total population during a defined period. It is often expressed as deaths per 1,000 population per year.
No. This calculator performs a basic mortality rate calculation. It is not a mortality prediction model calculator, clinical risk score, or personal medical prediction tool.
