How to shorten my code?

Code:

salary_range_report()
{
	echo -e ${underline}$redYellow"\nSalary Range Report\n"
	tput sgr0

	count_0_to_999=0
	count_1000_to_2999=0
	count_2000_to_5999=0
	count_6000_to_9999=0
	count_10000_above=0

	for i in `cut -d "," -f4 $PAYROLL` #Loop Salary
	do
		if [ $i -lt "999" ] && [ $i -gt "0" ]
		then
			let "count_0_to_999 = count_0_to_999 + 1"
		elif [ $i -gt "1000" ] && [ $i -lt "2999" ]
		then
			let "count_1000_to_2999 = count_1000_to_2999 + 1"
		elif [ $i -gt "2000" ] && [ $i -lt "5999" ]
		then
			let "count_2000_to_5999 = count_2000_to_5999 + 1"
		elif [ $i -gt "6000" ] && [ $i -lt "9999" ]
		then
			let "count_6000_to_9999 = count_6000_to_9999 + 1"
		else
			let "count_10000_above = count_10000_above + 1"
		fi
	done

	echo -e "Salary Range\t\tTotal"
	echo -e "\$0 -999\t\t\t$count_0_to_999"
	echo -e "\$1000 -2999\t\t$count_1000_to_2999"
	echo -e "\$2000 -5999\t\t$count_2000_to_5999"
	echo -e "\$6000 -9999\t\t$count_6000_to_9999"
	echo -e ">\$10,000\t\t$count_10000_above"
	
	
	echo -en "Hit [Enter] to return to main menu..."
   	read
}

Hi there everyone, as my title stated, how can i shorten my code? Im new to shell scripting and i think my code can be shorten to just a line.
My code is working perfectly and able to generate a report.
I saw people using awk utility and just one line , they are doing the same thing as my long code above.

So i hope someone could help me start up with the awk so i can see if im able to work out with it
Thank you guys!

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib 
       -R /usr/xpg4/lib -lcurses [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int echo(void);

       int noecho(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

       Upon successful completion, these functions return OK. Otherwise, they return ERR.

ERRORS

       No errors are defined.
