Sheet Names & Structure

The template is organized into three primary sheets:

• Loan Calculator (Main Sheet): Central sheet for all input values and outputs.
• Monthly Payment Schedule: Detailed table showing monthly breakdowns of principal, interest, and remaining balance.
• Business Operations Summary: A high-level dashboard summarizing key financial indicators related to loan impacts on business operations (e.g., cash flow changes, cost of borrowing).

The Monthly Payment Schedule sheet contains a dynamic table with the following columns:

The Business Operations Summary sheet displays key metrics with color-coded indicators:

• Total Cost of Borrowing (in % of loan amount)
• Monthly Impact on Cash Flow (negative = outflow)
• Suggested Loan-to-Value Ratio (for home use or business property acquisition)
• Break-even point estimate for return on investment

Formulas Required

All core calculations are powered by Excel’s built-in financial functions:

• =PMT(rate, nper, pv): Calculates monthly payment based on interest rate, loan term (in months), and present value.
• =IPMT(rate, per, nper, pv): Determines interest portion for a given month.
• =PPMT(rate, per, nper, pv): Calculates principal repayment for each period.
• =SUMIFS() and =ROUND(): Used to calculate total interest and round values to two decimal places for clarity.
• Dynamic range references: All formulas dynamically update when inputs change—no manual recalculation required.

Conditional Formatting

To enhance user experience and provide visual feedback, the template includes:

• Color scale on Monthly Payment column: Green for low payments, red for high (above 10% of monthly income).
• Highlighting high interest rates (>7%) in yellow, indicating potential cost inefficiencies in business operations.
• Warning rules on total interest paid: If interest exceeds 30% of loan amount, a red border appears with a note: “Consider lower-rate alternatives.”
• Conditional cell text: If monthly payment > 15% of household income, the cell displays "High Risk – Review Budget."
