What is the Fisher equation?

The Fisher equation states: real interest rate ≈ nominal interest rate − inflation rate. More precisely: (1 + real) = (1 + nominal) / (1 + inflation).

What has the average US inflation rate been historically?

The US average annual inflation rate from 1914 to 2024 is approximately 3.2%. The post-2020 surge pushed rates temporarily above 8%, but the Federal Reserve targets 2% long-term.
