Answer: Your new rent will be $ a month — that's $120 more per month, or $1440 more per year.

Type of calculation: Finding the value after a percentage increase, then scaling the monthly increase up to a full year.
How to use the calculator: Use the Value Increase Calculator (“Original increased by Increase% is what?”). Enter $1500 [A] and 8% [B] to get the new monthly rent.
The formula:
Monthly increase = (Increase % / 100) × Current rent
Monthly increase = (8 / 100) × $1500 = 0.08 × $1500 = $120
New monthly rent = $1500 + $120 = $1620
Yearly increase = $120 × 12 = $1440
