Answer: The new payment is $ .

Type of calculation: Calculating a value after a percentage increase.
How to use the calculator:
Option 1 (Direct method): Use the Value Increase Calculator (“Original increased by Increase% is what?”). Enter $1000 [A] and 10% [B]. It will show you the new payment amount.
Option 2 (Step-by-step method):
Step 1: Find the dollar amount of the increase. Use the Basic Percentage Calculator (“What is A% of B?”). Enter 10 [A] and $1000 [B]. It will calculate 10% of $1000.
Step 2: Add that increase to the previous payment amount.
The formula:
We want the new payment after a 10% increase from $1000.
Amount of increase = (10 / 100) × $1000 = 0.1 × $1000 = $100
New payment = $1000 + $100 = $1100
