Sheet Names

The template includes the following key sheets:

• Loan Input: Primary data entry sheet for users to input loan details.
• Repayment Schedule: Automatically generated table showing monthly payments, interest, principal, and remaining balance.
• Scenario Analysis: Enables users to test different interest rates, terms, or down payments with a "what-if" model.
• Dashboards & Insights: Visual summary of key metrics such as total cost of borrowing, amortization curve, and payment flexibility.
• Productivity Tracker: Tracks how frequently the calculator is used and which scenarios are most common—helping users optimize financial planning routines.

Table Structures and Columns

All data tables are structured for clarity, scalability, and usability in a startup setting.

1. Loan Input Sheet

2. Repayment Schedule Table (Repayment Schedule Sheet)

Formulas Required

The core of this template relies on Excel’s financial functions to ensure accuracy:

• =PMT(rate, nper, pv, [fv], [type]): Calculates monthly payment based on interest rate, term (in months), and present value.
• =IPMT(rate, per, nper, pv): Returns the interest portion of a specific payment.
• =PPMT(rate, per, nper, pv): Returns the principal portion of a specific payment.
• =FV(rate, nper, pmt, pv): Calculates future value to project loan balance at maturity.
• =ROUND(value, 2): Ensures all monetary values are displayed with two decimal places for clarity.
• Dynamic arrays (if Excel 365/2021+): Used in the Scenario Analysis sheet to generate multiple tables instantly without manual copying.

Conditional Formatting

To enhance usability and promote financial awareness, conditional formatting is applied:

• Red Highlighting: If monthly payment exceeds 30% of monthly revenue (in a separate revenue input cell).
• Yellow Alert: When interest rate exceeds 15%, indicating potentially high borrowing cost.
• Green Status: If the loan term is less than 3 years and down payment is over 20%.
• Auto-Filtering: On all tables to allow quick sorting by month, balance, or payment amount.
