The Mortality Table Calculator is a practical, data-driven tool designed to estimate survival and death rates across a range of ages. By inputting a starting age, the number of years you want to project, and an annual mortality rate, the calculator generates a table showing how many individuals survive and how many pass away each year.
This type of calculator is essential for actuarial analysis, life insurance planning, retirement projections, health research, and demographic studies. Instead of relying on static charts, you can instantly model different scenarios and mortality rates to fit your specific needs.

ow to Use the Mortality Table Calculator
Using the Mortality Table Calculator is simple and intuitive. Here’s a step-by-step breakdown:
- Enter the Start Age
- Type in the age at which you want to begin the projection (e.g., 40 years old).
- Enter the Number of Years
- Choose how many years you want the projection to cover (from 1 to 100 years).
- Enter the Annual Mortality Rate (%)
- This is the expected yearly death rate as a percentage (e.g., 2.5%).
- The calculator will convert it to a decimal for calculations.
- Click "Calculate"
- The tool instantly generates a table showing the age, the number of survivors, and the number of deaths for each year.
- Review the Results
- Use the table to analyze trends, identify risk points, and make informed decisions.
- Reset if Needed
- Click the “Reset” button to clear all inputs and results to start a new calculation.
Example Scenario
Example:
A researcher wants to model the survival of a group starting at age 50, over a 10-year period, with an annual mortality rate of 3%.
- Start Age: 50
- Years: 10
- Mortality Rate: 3
Result (excerpt):
| Age | Survivors | Deaths |
|---|---|---|
| 50 | 1000 | 30 |
| 51 | 970 | 29 |
| 52 | 941 | 28 |
| 53 | 913 | 27 |
By the end of the period, the number of survivors has dropped significantly, providing clear insight into population decline over time.
Why Use a Mortality Table Calculator?

- Actuarial Studies – Build data models for mortality assumptions.
- Education & Training – Demonstrate survival rate calculations in classes.
15 Detailed FAQs about the Mortality Table Calculator
- What is a mortality table?
A mortality table is a chart showing the probability of death for each age group in a population. - What starting population does this calculator use?
The calculator assumes a starting population of 1,000 individuals for projections. - Can I change the starting population?
In the current version, the starting population is fixed, but it can be modified in custom versions. - What is the mortality rate in this context?
It’s the percentage of the population expected to die each year. - Why do results change each year?
Each year’s survivors are fewer than the previous year, so deaths also decrease proportionally. - Can I project for more than 100 years?
No, the maximum limit is 100 years for practical usability. - What happens if mortality rate is 0%?
The table will show no deaths, and survivors remain constant. - What happens if mortality rate is 100%?
All individuals die in the first year, ending the projection immediately. - Can I use decimal mortality rates?
Yes, you can enter rates like 2.5% for more precise projections. - Does the tool account for births?
No, it only models deaths, not population growth. - Is this calculator suitable for human populations only?
No, it can be used for any species or group where mortality rates apply. - How accurate are the results?
The tool assumes a constant mortality rate and does not account for external variables. - Can I export the table?
Not directly, but you can copy the table into a spreadsheet for further analysis. - Does age impact the mortality rate in this tool?
No, the mortality rate is fixed per calculation, but you can run multiple scenarios. - Is this tool free to use?
Yes, it’s completely free and available online without registration. - Can I use it for insurance underwriting?
Yes, but for preliminary modeling—professional actuarial methods should be applied for final decisions. - How is this different from life expectancy calculators?
This tool gives year-by-year breakdowns, not just an average lifespan. - Can I calculate backwards?
No, it only projects forward from a starting age. - Does the tool save my results?
No, you will need to save results manually if you want to keep them. - Can it be used for COVID-19 or disease modeling?
Yes, provided you have a reliable mortality rate estimate for the affected population.
