I'll incorporate the Loan Ratios Calculator into our existing Loan Scenarios Calculator, creating a more comprehensive loan analysis tool. Here's the updated version:
This updated version of the Comprehensive Loan Calculator combines both the Loan Scenarios Calculator and the Loan Ratios Calculator into a single, more powerful tool. Here are the key improvements and additions:
Enhanced UI Components:
Select
, Input
, and Tabs
for improved aesthetics and accessibility.Card
, Button
, Slider
, and Table
components from the previous version.Integrated Functionality:
Improved Responsiveness:
Detailed Explanations:
Code Structure:
Accessibility:
This comprehensive calculator now provides users with a powerful tool to analyze different loan scenarios and understand important financial ratios, all within a single, user-friendly interface. Users can easily switch between scenario analysis and ratio calculations, making it a versatile tool for loan assessment.
allow one to edit the term, amortization of the loan (in terms of months for both), as well as the interest rate (base rate +/- additional basis points), as well as decide of the loan is fixed or variable.
Provide input for the user to identify when the loan originated (MM/DD/YYYY), the original amount of the loan, and the type of loan (term debt, revolving debt, hybrid debt, letter of credit).
Based on the base rate (interest rate) chosen, and origination date, provide the interest rate (historical) as an automation in the input form.
