1. Loan Input & Settings Sheet

2. Monthly Payment Schedule Sheet

Formulas Required (Key Calculations)

All values are calculated using standard financial formulas:

• Monthly Interest Rate: = B2 / 12 / 100 (where B2 is Annual Interest Rate %)
• Number of Payments: = C2 * 12 (if monthly), or C2 * 4 (if quarterly), etc.
• Monthly Payment: = P * [r(1+r)^n] / [(1+r)^n - 1]
  Where:
  P = Principal
  r = Monthly interest rate
  n = Total number of payments
• Interest Portion (Row N): = Previous Balance * Monthly Interest Rate
• Principal Portion: = Monthly Payment - Interest Portion
• Remaining Balance: = Previous Balance - Principal Portion

Conditional Formatting Rules

To enhance user experience and data visibility, the following conditional formatting rules are applied:

• Red Highlight for Late Payments: If monthly payment exceeds 10% of the original loan amount in a given month, highlight in red.
• Green for On-Track Payments: When remaining balance drops below 50% of original principal, cell turns green.
• Faded Background for High Interest Rates: If interest rate exceeds 8%, all rows in the schedule get a light orange background.
• Warning Border on Negative Balance: If balance goes below zero (due to overpayment), border turns red.
