• IPMT(rate, per, nper, pv): Returns interest portion of a specific payment.
• PPMT(rate, per, nper, pv): Returns principal portion of a specific payment.
• SUM(): Aggregates interest and total payments across months.
• =ROUND(value, 2): Ensures currency values are displayed with two decimal places.
• =IF(Loan_Amount <= 0, "Invalid Input", Loan_Amount): Validates user input to prevent errors.

CONDITIONAL FORMATTING

To enhance usability and provide visual feedback:

• Highlight Monthly Payments exceeding 10% of monthly income: In red for financial alerting.
• Color-code interest payments by month (e.g., blue → low, orange → high): Helps visualize interest trends.
