I have tried to figure out where the off by one error is and have had no luck. I am an absolute beginner at programming. The increase is supposed to start on year two, but my code adds it to year one. Thanks in advance for any and all help!

```
##
# salaryschedule.py
# 2/15/2017
# This program will calculate and print the salary schedule for years 1 
# through 30 for the teachers in Murdock County. For each year of 
# experience, up to 20 years, the salary is increased by 2%. 
# Each year after 20, the salary stays the same as year 20.
##

RATE = 2.0
INITIAL_SALARY = 37238.00
salary = INITIAL_SALARY
year = 1

print("Murdock County")
print("Teacher Salary Schedule")
print()
print("Year          Salary")
print("----          ------")

while year < 31 :
    increase = salary * RATE / 100
    salary = salary + increase
    print("%4d  %15.2f"  % (year, salary))
    year = year + 1
