If you want to increase the amount, enter either a dollar amount or a percentage in the appropriate field below the Apply Budget Options field. The specified amount is then added to the base amount and put in the second highlighted field; the increase amount is then added to the number in the second field and put in the third field, and so on to the end of the selected periods. For example, if you enter $100 in January and increase by $10, you would wind up with $100 in January, $110 in February, $120 in March, $130 in April, and so on.
If you want to decrease the amount, enter the amount or percentage as a negative number, that is, put a minus sign in front of it. The specified amount is then subtracted from the base amount in the first highlighted field and the result is placed in the second field; the decrease amount is then subtracted from that number and put in the third field, and so on to the end of the selected periods. For example, if you enter $100 in January, highlight January, February, March, and April, and then specify -$10, you would wind up with $100 in January, $90 in February, $80 in March, and $70 in April.
