Key Formulas Required

The template relies on powerful and reliable Excel functions to ensure dynamic calculations:

• =PMT(rate, nper, pv, [fv], [type]): Calculates monthly payment based on interest rate, loan term, and principal.
• =IPMT() and =PPMT(): Break down interest and principal components in each period.
• =SUMIFS(): Used in summary reports to filter data by rate or term type.
• =IF() + AND() logic: Validates input ranges (e.g., ensures interest rate is between 0% and 15%).
• =DATEDIF() or =DATE(): For calculating time intervals in payment schedules.
• Array formulas or dynamic arrays (Excel 365/2021): Used in the comparison dashboard to generate scalable reports without manual input.

Conditional Formatting

To enhance visual clarity and user awareness, conditional formatting is applied:

• Red highlight on monthly payments exceeding 10% of monthly revenue (business risk alert).
• Yellow background when interest rate exceeds 8%, indicating high cost.
• Green highlight for low-interest options or short-term loans with minimal total cost.
• Data bars in the amortization schedule show progression of balance over time.
• Error indicators (e.g., red triangle) appear when inputs are invalid or out of range.

Instructions for the User

User instructions are clearly documented within each sheet:

• Begin by entering the loan amount, interest rate, and term in the Main Loan Calculator.
