This was our very first online i-Tree tool, launched in May of 2009! i-Tree software has changed a lot since then, but most importantly the science has continued to evolve as well. Now, the best USDA Forest Service science concerning tree benefits can be found at The tool that best mimics the NTBC is i-Tree Design and NTBC users will be sent there. Please visit our website and explore other i-Tree tools.

Understanding This Tool:

The Tree Benefit Calculator allows anyone to make a simple estimation of the benefits individual street-side trees provide. This tool is based on i-Tree’s street tree assessment tool called STREETS. With inputs of location, species and tree size, users will get an understanding of the environmental and economic value trees provide on an annual basis.

The Tree Benefit Calculator is intended to be simple and accessible. As such, this tool should be considered a starting point for understanding trees’ value in the community, rather than a scientific accounting of precise values. For more detailed information on urban and community forest assessments, visit the i-Tree website.
