Common Money Calculations

This percent calculator for money handles several common financial scenarios:

Tips: Determine the appropriate tip amount based on the bill and percentage.
Interest: Compute interest earned or paid on a principal amount.
Increases/Decreases: Adjust amounts by a percentage increase or decrease.

Calculation Type	Example	Formula
Discount	10% off $100	100 × (10 / 100) = $10
Tip	15% tip on $50	50 × (15 / 100) = $7.50
Interest	5% interest on $200	200 × (5 / 100) = $10

The Formula Explained

The basic formula for percentage calculations is:

Result = Base Amount × (Percentage / 100)

Where:

Base Amount: The original amount you're calculating from.
Percentage: The percentage value you want to apply.

For example, to calculate 25% of $80:

Result = 80 × (25 / 100) = 20

So, 25% of $80 is $20.

Worked Examples

Example 1: Calculating a Discount

You find a shirt that costs $75 with a 30% discount. How much do you save?

Discount = 75 × (30 / 100) = $22.50

You save $22.50, so the final price is $52.50.

Example 2: Calculating a Tip

Your bill is $60, and you want to leave a 18% tip. How much should you tip?

Tip = 60 × (18 / 100) = $10.80

You should leave a $10.80 tip.

Example 3: Calculating Interest

You deposit $1000 at a 4% annual interest rate. How much interest will you earn in one year?

Interest = 1000 × (4 / 100) = $40

You will earn $40 in interest after one year.
