実用的なユースケース
日本では年収が給与の基本的な表現方法です。転職サイト（リクナビNEXT、doda、ビズリーチ）の求人票には年収範囲が記載されています。月収ベースで交渉することも多いです。日本の給与明細では、基本給に加えて、各種手当（通勤手当、住宅手当、家族手当、時間外手当）や賞与（ボーナス、夏季・冬季）が含まれます。社会保険料（健康保険、厚生年金、雇用保険、介護保険）と源泉所得税・住民税が控除されます。年収500万円の会社員の場合、手取りは約380万円程度です。フリーランスは単価を日額や時間単価で設定します（エンジニアで60-120万円/月）。転職時の年収交渉では、基本給のアップだけでなく、リモート手当やストックオプションも考慮します。中小企業の経営者は毎月の給与計算と年末調整、社会保険料の事業主負担分を計算するために給与計算ソフトを利用します。派遣社員の時給（1,200-2,500円）も頻繁に換算が必要です。週40時間労働の基準を超える割増賃金（25%増し）の計算も重要です。
