FORMULAS REQUIRED

The template leverages standard Excel financial functions:

• =PMT(): Calculates monthly payment based on rate, term, and principal.
• =IPMT() and =PPMT(): Break down interest and principal per period.
• =FV(): Used in scenario analysis to project future value of loan balances.
• =SUMIF() and =AVERAGEIF(): For dynamic summarization across scenarios.
• =ROUND(): Ensures consistent decimal precision for financial outputs (e.g., 2 decimals).

All formulas are dynamically linked so that changing any input automatically updates the entire payment schedule and summary dashboard. The template also includes error-checking formulas to alert users if inputs are invalid (e.g., negative interest rates or zero terms).

CONDITIONAL FORMATTING

The template applies conditional formatting to highlight key financial insights:

• High Monthly Payment Flag: If monthly payment exceeds 30% of business income, cells turn red.
• Interest Cost Warning: If interest cost exceeds 12% of principal, the row is highlighted in yellow.
• Break-Even Highlight: The month when break-even occurs is bolded and shaded in green.
• Scenario Comparison Color-Coding: Each scenario uses distinct colors (e.g., blue for fixed, orange for variable) to improve readability.
