Estimate your BNG costs for free, without the guesswork

How much should you budget for off-site Biodiversity Net Gain (BNG) units? It’s a question developers, planning consultants and ecologists need to answer, often while juggling 50+ other project demands.

Our free BNG Price Calculator makes that task easier. Upload your DEFRA metric, add your project details, and get an estimate of your off-site BNG unit costs in seconds.

But don’t just take our word for it. Here’s what users have told us.

Getting an initial estimate shouldn’t take hours of searching or chasing suppliers. The calculator extracts your unit requirements from your metric and provides low, average and high price estimates based on real market pricing data.

You can use those figures to build an initial budget, discuss likely costs with your client, or understand how changes to your project could affect your spend.

A biodiversity metric tells you what your project needs, but it doesn’t tell you what those units might cost.

The calculator helps bridge that gap, giving you a straightforward breakdown of your requirements and indicative pricing ranges. Whether you work with BNG regularly or are getting to grips with your first project, it gives you a clearer starting point.

Having a market-based estimate early helps you plan with more confidence and avoid unexpected costs later.

The estimates are indicative, with final prices depending on the units and supplier selected. When you’re ready to explore buying options, our team can help you take the next step.

The calculator is completely free, with no subscription or trial period.
