<prompt> Human: Hi Reddit. I have about 30k in student loans from undergrad that I am paying off. My mom recently got a promotionbonus and unexpectedly gifted me 4k to use towards my student loans. I also plan on using around 800-1000 of my tax return money to help pay down my debts. I am familiar with both the avalanche and the snowball methods of paying these debts off, and I am more inclined towards the avalanche method, since I would like to pay as little interest as possible. I am wondering what the best way to allocate this 5k-ish towards my loans would be.Here are the totals and interest rates:Loan 1: 7033.43 at 6.550Loan 2: 4006.01 at 3.610Loan 3: 2,836.85 at 3.610Loan 4: 8179.46 at 4.410Loan 5: 7808.78 at 4.040Does it make the most sense to put all 5k towards the loan at 6.550? Or should I spread it between multiple loans, perhaps putting 3k towards the highest interest loan, and 1k each towards the next highest interest rate loans?I have been trying to do the math and I cant make heads or tails of it past a certain point. Whats the most economically efficient way to allocate this money?  <response>: Does it make the most sense to put all 5k towards the loan at 6.550? Yes this is the most efficient payoff option.
