Free Biological Age Calculator Spreadsheet

Get started with biological age calculations using our free Google Sheets template. This spreadsheet automatically calculates and charts ChronoAge, PhenoAge, and LinAge biological age assessments using the Biometric Calculator API.

For detailed API documentation, see the ChronoAge Calculator API, PhenoAge Calculator API, and LinAge Calculator API. For scientific foundations, see the PhenoAge scientific foundation and LinAge scientific foundation.

Access the Spreadsheet

Open the Free Biological Age Calculator Spreadsheet

The spreadsheet is free to access and copy. Simply make a copy to your own Google Drive to start using it with your own data.

Features

The spreadsheet provides:

• ChronoAge Calculation: Precise chronological age from birth date and test date
• PhenoAge Calculation: Biological age using 9 clinical biomarkers
• LinAge Calculation: Advanced biological age using 61+ clinical parameters
• Automatic Charting: Visual trends of biological age over time
• Multiple Test Tracking: Compare results across multiple test dates
• Easy Data Entry: Simple interface for entering test values

Requirements

To use the spreadsheet, you’ll need:

1. API Key: A valid API key from Lincoln Cannon LLC
   • Contact us to obtain an API key
   • See Biometric Calculator pricing for details
2. Google Account: To access and copy the spreadsheet
3. Test Data: Laboratory results for the biomarkers you want to calculate

How to Use

Step 1: Copy the Spreadsheet

1. Open the spreadsheet link
2. Click File → Make a copy to create your own editable version
3. Save the copy to your Google Drive

Step 2: Configure Settings

1. Open the Settings sheet
2. Enter your API key in the designated field
3. Enter the birth date of the person for whom you’ll provide test data
4. Select the sex (male or female) of the person

Step 3: Enter Test Data

1. Open the Data sheet
2. For your first set of tests, edit the Value fields in the Test section of column E
   • PhenoAge: Enter values for all rows with light blue backgrounds
   • LinAge: Enter values for any available parameters
   • ChronoAge: Test date is automatically used
3. The Value fields in the Result section will automatically update with calculated biological ages

Step 4: Track Multiple Tests

To track biological age over time:

1. Copy the Value fields from the Result section of column E
2. Paste them into the next available column to the right
3. Edit the Value fields in the Test section of that new column with your new test data
4. Results will automatically update

Step 5: View Charts

1. Open the Chart sheet
2. View automatic visualizations of biological age trends over time
3. Charts update automatically as you add new test data

What Gets Calculated

ChronoAge

Calculates precise chronological age from birth date and test date, providing detailed breakdowns in years, months, weeks, and days.

Required Inputs:

• Birth date
• Test date

PhenoAge

Calculates biological age using 9 essential clinical biomarkers based on peer-reviewed research by Dr. Morgan Levine.

Required Inputs:

• Birth date
• Test date
• Albumin (g/dL)
• Alkaline Phosphatase (ALP) (U/L)
• Creatinine (mg/dL)
• C-Reactive Protein (CRP) (mg/L)
• Glucose (mg/dL)
• Lymphocyte Percentage (%)
• Mean Corpuscular Volume (MCV) (fL)
• Red Blood Cell Distribution Width (RDW) (%)
• White Blood Cell Count (WBC) (K/μL)

LinAge

Calculates advanced biological age using 61+ clinical parameters, providing the most comprehensive biological age assessment available.

Required Inputs:

• Birth date
• Test date
• Sex (male or female)
• Up to 61+ clinical parameters (see LinAge Calculator API for complete list)

Understanding Your Results

Biological Age vs. Chronological Age

• ChronoAge: Your actual age based on your birth date
• Biological Age: An estimate of your body’s functional age based on biomarkers
• Difference: The gap between biological and chronological age
  • Negative difference: Your biological age is younger than your chronological age
  • Positive difference: Your biological age is older than your chronological age

Interpreting Trends

The chart sheet helps you visualize:

• Changes in biological age over time
• Effectiveness of lifestyle interventions
• Impact of health improvements or declines
• Comparison between different biological age algorithms (PhenoAge vs. LinAge)

Tips for Best Results

1. Consistent Testing: Use the same laboratory for all tests when possible
2. Complete Data: Enter all required biomarkers for accurate calculations
3. Regular Tracking: Test at regular intervals (e.g., every 3-6 months) to see trends
4. Same Conditions: Try to test under similar conditions (time of day, fasting status, etc.)
5. Clinical Context: Results should be interpreted alongside clinical assessments
