# How is FPPS rate calculated

## FPPS rate = 1 + (Sum of Block Transaction Fees / Sum of Block Subsidies)

You may use data from Blockchair or Mempool.space, but it's easier to work with Blockchair's data which is aggregated by UTC day:

[https://gz.blockchair.com/bitcoin/blocks/](https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgz.blockchair.com%2Fbitcoin%2Fblocks%2F&data=05%7C01%7CDLiang%40foundrydigital.com%7Cb151698d6c1b49e4386a08db681b65d9%7C6681433fa30d43cd88818e964fa723ad%7C0%7C0%7C638218239100154074%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=AokKGyqaMiPgFiMORuWUs59IgadpQkLLP8fNPt3GiS0%3D&reserved=0)

 

Steps to calculate:

1. Download desired file from [https://gz.blockchair.com/bitcoin/blocks/](https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgz.blockchair.com%2Fbitcoin%2Fblocks%2F&data=05%7C01%7CDLiang%40foundrydigital.com%7Cb151698d6c1b49e4386a08db681b65d9%7C6681433fa30d43cd88818e964fa723ad%7C0%7C0%7C638218239100154074%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=AokKGyqaMiPgFiMORuWUs59IgadpQkLLP8fNPt3GiS0%3D&reserved=0) 
     1. For example, if you want data for 2023-05-30, then download the file called blockchair\_bitcoin\_blocks\_20230530.tsv.gz
2. Open and extract the downloaded GZ file using 7-Zip software: [https://7-zip.org](https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2F7-zip.org%2F&data=05%7C01%7CDLiang%40foundrydigital.com%7Cb151698d6c1b49e4386a08db681b65d9%7C6681433fa30d43cd88818e964fa723ad%7C0%7C0%7C638218239100154074%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=KFsBdEMKKaNz7%2BBnLb1j2GL3wLQs5UfBv%2Bn%2BE2UJsNc%3D&reserved=0)
3. Open the TSV file with Microsoft Excel
4. Sum up the "fee\_total" column to calculate "Sum of Block Transaction Fees" for that day excluding the 3 highest fee and 3 lowest fee blocks
5. Sum up the "generation" column to calculate "Sum of Block Subsidies" for that day excluding the 3 highest fee and 3 lowest fee blocks
6. Calculate FPPS rate with this formula:  
     1. FPPS rate = 1 + (Sum of Block Transaction Fees / Sum of Block Subsidies)
