<prompt> Human: Reddit, I need help with a loan for a wedding ring. I want to make sure that I am thinking correctly with this stressful purchase :DThe ring is 2500 after the sale and with the lifetime warranty put on. The APR for the loan is 2.1. In a loan calculator paying 18 months that comes out 141 with the loan only costing 45 for the life of it.The alternative is paying 20 down 520 and making payments for one year no interest at 170. I can make the down payment but not sure about that high of payments with being a full time student. Am I thinking correctly and which is the most viable option?Do I need a lifetime warranty on the wedding ring?Thank you, RedditEdit: my girlfriend and I talked and we decided to go in on the ring together, paying half the down payment then half for the monthly payments.Thank you for the tough love  <response>: Youre not thinking correctly because you should not finance a ring. If the person is willing to be with you for the rest of your life, they should be willing to wait for a proposal until you have the money to buy a ring outright.
