<prompt>  Human: So, I have 8 primary sources of debt most of which are student loans. I have successfully lowered minimum payments to give myself as much room possible to snowball. I know which snowball to do first as I can pay off the debt if I buckle down in about 5 months, but the others are MUCH larger. Is there a program or widely used spreadsheet that can let me know the most efficient way to attack each loan? My monthly contribution will remain largely the same, but I am not sure which order to target my payments.It would also be nice to track the progress over time, but my main concern is creating a proper pecking order when using all of my resources at paying off these debts.
