Excel Template Description: Growth Planning Loan Calculator (Financial View)

Overview of Template Structure

• Main Calculator: Core loan calculation engine with interactive inputs and amortization schedule.
• Growth Forecast Dashboard: Visual representation of projected cash flows, debt servicing capacity, and growth milestones.
• Scenario Comparison Matrix: Side-by-side analysis of multiple financing options under varying conditions.
• Data & Assumptions: Centralized input zone for user-defined financial parameters and key metrics.

Sheet 1: Main Calculator – Core Loan Engine

Table Structure:

Columns and Data Types:

• Period: Integer (1, 2, 3…), represents the payment number in the amortization schedule.
• Payment Date: Date type (formatted as MM/DD/YYYY), automatically calculated based on start date and payment frequency.
• Pmt. Amount: Currency (e.g., $1,245.67), constant value for fixed-rate loans or dynamically adjusted for variable rates.
• Principal: Currency, portion of payment applied to loan balance reduction.
• Interest: Currency, interest accrued on the remaining outstanding principal.
• Balloon Payment (if applicable): Currency, optional large final payment if defined in assumptions.
• Cumulative Principal Paid: Currency, running total of all principal payments made to date.

Key Formulas Required:

• =PMT(rate, nper, pv): Calculates fixed monthly payment amount using loan rate, number of periods, and present value.
• =PPMT(rate, period, nper, pv): Computes principal portion of a given payment.
• =IPMT(rate, period, nper, pv): Calculates interest portion for a specific payment.
• =IF(AND(period=final_period), balloon_payment + principal_amount, 0): Handles optional balloon payments in the final period.
• =SUM($D$2:D2): For cumulative principal paid, with absolute referencing for consistent calculation.

Conditional Formatting:

• Highlight rows where interest > 50% of total payment in red (indicating high-interest burden).
• Color-code payments made in the past (light gray) vs. upcoming (white) or future due dates.
• Apply data bars to "Principal" and "Interest" columns for visual comparison across periods.

Sheet 2: Growth Forecast Dashboard – Financial View

Key Components:

• Revenue Growth Chart: Line chart showing projected monthly/quarterly revenue over 3–5 years.
• Cash Flow vs. Loan Payments: Dual-axis bar and line chart comparing monthly cash flow (revenue minus expenses) with loan payment obligations.
• Debt-to-Equity Ratio Tracker: Trend line showing evolution of debt relative to equity, crucial for long-term growth sustainability.
• Growth Milestone Timeline: Gantt-style timeline marking key business goals (e.g., new product launch, market expansion) and financing milestones.

Sheet 3: Scenario Comparison Matrix – Strategic Planning Tool

Structure:

Data Types:

• Loan Option: Text label (e.g., "Bank A - 4.5%", "SBA Loan").
• Interest Rate: Decimal (e.g., 0.045).
• Tenure: Integer.
• Pmt. Amount: Currency, calculated via PMT formula.
• Total Interest Paid: Currency, calculated as (Pmt × Nper) – PV.
• DSR: Ratio (e.g., 0.35), computed as Total Loan Payments / Projected Monthly Cash Flow.

Conditional Formatting Rules:

• Highlight DSR > 0.4 in red (indicating high financial risk).
• Use gradient fill for "Total Interest Paid" to identify most cost-effective options.

Sheet 4: Data & Assumptions – Central Input Hub

Key Inputs:

• Loan Amount (Currency)
• Annual Interest Rate (%)
• Tenure (Years or Months)
• Pmt. Frequency (Monthly, Quarterly)
• Start Date (Date)
