Assumptions and disclosure
This calculator estimates expenses based on user-entered amounts.
It does not track actual bank transactions and does not account for inflation unless the user adjusts amounts manually.
It does not distinguish tax-deductible and non-deductible expenses. Some categories may overlap depending on how the user classifies spending.
Debt payments are included as cash-flow expenses, not as full liability balances.
