Formulas Required

The template leverages Excel’s most powerful financial functions:

• =PMT(rate, nper, pv, [fv], [type]): Calculates the monthly payment based on interest rate and loan term.
• =IPMT(rate, per, nper, pv): Returns interest paid in a specific period.
• =PPMT(rate, per, nper, pv): Returns principal paid in a specific period.
• =FV(rate, nper, pmt): Used to calculate the future value of the loan balance (zero at maturity).
• =RATE(nper, pmt, pv): Inverse function for calculating rate from known terms (used in scenario analysis).
• =SUM() and =ROUND(): For aggregating totals and formatting currency.

Conditional Formatting Rules

To enhance usability and alert users to financial risks:

• Highlight high interest rates (>7%) in red in the main calculator sheet.
• Maintain green shading for monthly payments under $500, yellow for $500–$1,000, and red above $1,500.
• Highlight negative cash flow impact in the Dashboard using red text if interest exceeds projected operating income.
• Auto-highlight overdue periods in the loan schedule (if applicable) with bold red formatting when a payment is missed.
