About Distance Matrix Calculator
A powerful tool for bulk-calculating distances and ETAs from CSV files with coordinate data, powered by NextBillion.ai Distance Matrix API.
The Distance Matrix Calculator is a bulk processing tool designed to help logistics teams, fleet managers, and data analysts calculate distances and estimated travel times (ETAs) for large sets of origin-destination pairs. Simply upload a CSV file with coordinate columns, and the tool will enrich each row with distance and duration data.
Built using NextBillion.ai's Distance Matrix API, the calculator provides accurate road-network-based distances and durations, making it ideal for logistics planning, delivery optimization, and transportation analysis.

Is the Distance Matrix Calculator free to use?
Yes! The Distance Matrix Calculator is free to use. You need to provide your own NextBillion.ai API key to process the data. You can get a free API key from the NextBillion.ai dashboard.
What file format does the tool support?
The tool supports CSV (Comma-Separated Values) files. Your CSV should contain separate columns for origin latitude, origin longitude, destination latitude, and destination longitude.
How does the auto-mapping feature work?
When you upload a CSV file, the tool automatically tries to detect and map columns based on common naming conventions like 'origin_lat', 'dest_lng', 'start_latitude', etc. You can always manually adjust the mappings if needed.
How many rows can I process at once?
You can process CSV files with hundreds of rows. The tool processes each row sequentially with a small delay between requests to avoid rate limiting. Processing time depends on the number of rows in your file.
What data is added to my CSV?
The tool adds three new columns: distance_km (distance in kilometers), eta_minutes (estimated travel time in minutes), and processing_status (Success or error details for each row).
What coordinate format should I use?
Use decimal degree format for coordinates. Latitude values should be between -90 and 90, and longitude values between -180 and 180. For example: latitude 40.7128, longitude -74.0060 for New York City.
What happens if some rows have invalid coordinates?
Rows with missing or invalid coordinates will be marked with an appropriate error status (e.g., 'Missing coordinates', 'Invalid coordinates', or 'Coordinates out of range'). The tool continues processing the remaining rows.
Is my data secure?
Yes, your CSV data is processed entirely in your browser and through your own API key. We do not store your data on any server. The API calls are made directly to NextBillion.ai's servers using your credentials.
Can I use this for fleet management and logistics?
The free tool is great for ad-hoc calculations. For enterprise fleet management and logistics with high-volume batch processing, consider NextBillion.ai's enterprise Distance Matrix API which supports many-to-many calculations and advanced routing options.
