住宅ローンは「定期支出」ではない?ローン返済の正しい記帳方法!

毎月のローン返済を全額「支出」として記録していませんか?実はこれでは財務レポートが歪んでしまいます!

ローン返済 ≠ 支出

毎月の返済額には2つの部分が含まれています:

  • 元金 — 借りたお金を返す部分(負債が減る)
  • 利息 — 借りたことへの対価(これが本当の支出)

定期支出 vs 定期返済

  • 定期支出:Netflix、家賃、保険料など純粋な消費
  • 定期返済:住宅ローン、カーローン、学生ローンなど元金+利息があるもの

よくある質問

Q1. Why is mortgage not an "expense"?
The principal portion of a mortgage payment moves money from your bank account into a home asset — it does not disappear. Only the interest is a true cost paid to the bank. Recording the entire payment as expense incorrectly shows you "losing" $2,000–3,000/month when most of it is just an asset transfer.
Q2. How do I record a mortgage correctly in Mr.Splitter?
Use the "Transfer" transaction type for the principal: from your cash account into the property asset account. Record the interest portion separately as an "Expense". Your monthly net worth then reflects reality.
Q3. Does the same approach apply to car, personal, and student loans?
Same logic: principal is a "Transfer", interest is an "Expense". Differences: vehicles depreciate (adjust the asset down periodically); personal loans have no matching asset (deduct directly from the liability); student loans are typically expensed first and amortized.
Q4. How should I record an early payoff?
The principal portion is still a "Transfer" (cash to loan liability), but any prepayment penalty should be recorded as an "Expense". Mr.Splitter supports custom categories, so you can add "Loan early-payoff fee" to track these.
