Formulas Required

The template uses a robust set of Excel formulas to ensure accuracy and responsiveness:

• PMT(rate, nper, pv): Calculates monthly payment based on interest rate, term, and loan amount.
• IPMT(rate, per, nper, pv): Determines interest portion of a specific payment.
• PPMT(rate, per, nper, pv): Computes principal portion of each installment.
• =SUMIFS(): Used in the Breakdown Sheet to categorize loan costs by function (e.g., “Marketing” or “Hardware”).
• =IF(loan_amount > 50000, "High Risk", "Standard"): Flags high-volume loans for further review.
• =ROUND(amount, 2): Ensures currency values are displayed with two decimal places.

Conditional Formatting Rules

To improve user experience and visibility:

• Monthly payments exceeding 10% of monthly operating income are highlighted in red.
• Total interest paid above 30% of principal triggers a yellow warning flag.
• High-risk loan scenarios (e.g., >$50,000 or >24 months) are shaded with orange background and bold text.
• Rows where balance drops below $1,000 are marked in green for "early repayment" opportunity.
