Loan Input Sheet

Calculation Engine Sheet

Formulas Required

• =PMT(B3/12, B4*12, -B2): Calculates monthly payment from principal, rate, and term.
• =SUM(B3:B5): Total repayment amount (principal + interest).
• =IF(C3>0.15,"High Risk","Medium/Low Risk"): Conditional risk assessment based on interest rate.
• =ROUND(INDIRECT("G"&ROW()-1),2): Dynamic amortization table generator (for periodic payments).
• =IF(ISBLANK(D3),"Pending","Approved"): Workflow status updater to prevent invalid entries.
• ='Loan Input'!$B$2 * 0.05: Default interest rate override (if user leaves field blank).

Conditional Formatting Rules

• If Monthly Payment > $1,500 → Highlight in red with "High Cost" label.
• If Risk Score > 0.15 → Apply yellow fill and bold font.
• If Application Date is more than 30 days old → Show gray background and warning icon.
• Cells where Payment Frequency is not "Monthly" → Change to blue text with a tooltip explaining the impact on total payments.

User Instructions

1. Open the Loan Input sheet and enter loan parameters such as principal, interest rate, term, and payment frequency.

2. Click “Calculate” (button) or press Enter to auto-fill monthly payments and related metrics in the Calculation Engine.

3. Review the amortization schedule in the Amortization Schedule section for detailed repayment breakdowns by month.

4. In the Data Log, track all changes over time using timestamps and user input history—ideal for workflow audit trails.

5. Use the Scenario Analysis sheet to compare different loan terms or interest rates side-by-side with a "What-If" analysis.

6. Generate reports via the Dashboards, which include charts summarizing repayment trends, risk exposure, and average processing times.

Example Rows

Recommended Charts & Dashboards

• Pie Chart: Distribution of loan types by interest rate ranges (e.g., 0–5%, 5–7%, >7%) – supports workflow optimization via risk profiling.
• Bar Chart: Monthly payment comparison across different loan terms – helps decision-makers evaluate cost efficiency.
• Line Chart: Total interest paid over time by loan tenure – visualizes amortization impact on financial planning.
• Heatmap: Shows frequency of high-risk loans (based on rate and term) across departments – enables proactive workflow intervention.
• Dashboard Summary Sheet: Aggregates KPIs such as average processing time, rejection rates, and loan approval efficiency — central to workflow optimization efforts.

In summary, this Data Version of the Loan Calculator is a powerful instrument that goes beyond simple computation. By embedding workflow logic, real-time validation, dynamic reporting, and audit trails, it enables organizations to optimize operational efficiency in loan processing—from initial assessment to final settlement.
