Suppose that you have a $$20,000$ unsubsidized student loan that is currently deferred. You plan to complete the final $1\mathrm{.}5$ years of undergrad $($assume $18$ months until graduation$)$ and then complete a $2$ year master's program. Upon graduating from your master's program, the loan will enter repayment, and then you'll pay off the loan over $10$ years. The loan's interest rate is $7\%,$ compounded monthly. While the loan is deferred, you are not required to make any payments, but it is still accruing interest. So$,$ you consider making interest$-$only payments each month until you finish your master's program. Prepare monthly amortization tables for both scenarios. How much do you save when making these voluntary payments?
