Table Structures & Columns

2. Amortization Schedule Sheet

A full monthly breakdown of payments over the loan term, formatted for clarity and analysis.

Formulas Required

• M monthly payment = P * [r(1+r)^n] / [(1+r)^n - 1]
  Where P = loan amount, r = monthly interest rate (annual rate/12), n = number of months.
• Total Interest Paid = (Monthly Payment × Total Months) – Loan Amount
• Remaining Balance in amortization schedule: Previous balance + interest – principal portion.
• Cost Control Ratio = (Total Cost of Loan / Original Principal) → Helps evaluate cost efficiency.
• All formulas are automatically recalculated when inputs change — no manual intervention required.

Conditional Formatting Rules

• High Interest Warning: If the interest rate exceeds 8%, cells in the "Annual Interest Rate" column will turn red.
• Cost Efficiency Highlight: In the Cost Control Dashboard, any loan with a cost ratio above 1.20 is shaded in yellow to flag high expense.
• Monthly Payment Exceeds Budget: If monthly payment exceeds user-defined budget limit (e.g., $500), the "Monthly Payment" cell turns orange.
• Remaining Balance Trend: In amortization schedule, balance decreases are highlighted in green to show progress.
