Understanding Discount Calculations

Introduction

This guide explains the formulas and concepts behind discount calculations.

Key Discount Concepts

• Original Price:
  The initial price of the item before any discounts.

• Discount Value:
  The amount or percentage by which the original price is reduced.

• Final Price:
  The price of the item after the discount is applied.

Discount Calculation Formulas

• Percentage Discount:
  Discount Amount = (Original Price * Discount Percentage) / 100
  Final Price = Original Price - Discount Amount

Understanding Percentage Calculations

Introduction

This guide explains the formulas and concepts behind percentage calculations.

Key Percentage Concepts

• Percentage:
  A way of expressing a number as a fraction of 100.

• Base Value:
  The original value to which a percentage is applied.

• Result Value:
  The value obtained after applying a percentage to the base value.

Percentage Calculation Formulas

• Percentage of a Number:
  Result = (Percentage / 100) * Base Value

• Percentage Increase/Decrease:
  New Value = Base Value + (Percentage / 100) * Base Value (for increase)
  New Value = Base Value - (Percentage / 100) * Base Value (for decrease)

Understanding Tip Percentages and Etiquette

Understanding Loan Calculations

Introduction

This guide explains the formulas and concepts behind loan calculations.

Key Loan Parameters

• Loan Amount (Principal):
  The initial amount of money borrowed.

• Interest Rate:
  The percentage charged by the lender for borrowing the money.

• Loan Term:
  The length of time you have to repay the loan.

• Monthly Payment:
  The amount you pay each month to repay the loan.

Loan Calculation Formulas

• Monthly Payment (M):
  M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
  Where:
  P = Principal loan amount
  i = Monthly interest rate
  n = Number of months
