We propose a very concise phenomenological formula for the anomalous magnetic moment of the muon. The formula only involves the Schwinger term and the muon-electron mass ratio, and the calculation result is 116592075.6(0.2) × 10^(-11), which is in excellent agreement with the latest experimental measurement from Fermilab in 2025, namely 116592071.5(14.5) × 10^(-11) [1], and the result is also better than the theoretical value of the Standard Model, namely 116592033(62) × 10^(-11) [2]. This concise formula offers new insights into the origin of the muon anomalous magnetic moment and also demonstrates that it can be calculated using a simpler and more efficient means.
