<p>The following discussion n FinAid.org gives a good example of capitalizing interest at work.</p>

<p>In-School Deferment Inflates the Loan Balance</p>
<p>A dependent student can borrow $5,500 in Federal unsubsidized Stafford loans during the freshman year in college, $6,500 during the sophomore year, $7,500 during the junior year and $7,500 during the senior year, for a total of $27,000. An independent student can borrow $4,000 more per year during the freshman and sophomore years and $5,000 more per year during the junior and senior years, for a total of $45,000. (The aggregate limits of $31,000 and $57,500 for dependent and independent students, respectively, are higher because the aggregate limits allow for more than four years to complete a Bachelor’s degree.) The interest rate on the Federal unsubsidized Stafford loan is 6.8%.</p>
<p>Let’s assume that each year’s loans are disbursed in two equal installments, one in September at the start of the fall semester and one in January at the start of the spring semester. Let’s also assume that the student defers repaying the loan during the in-school period and the 6-month grace period, with the accrued but unpaid interest capitalized monthly. Let’s ignore any origination and default fees, which are usually deducted from the disbursements.</p>
<p>Then a dependent student who borrows the maximum amount of Federal unsubsidized Stafford loans will have a loan balance of $31,978 upon entering repayment at the end of the grace period. This is $4,978 (18.4%) higher than the $27,000 borrowed. The monthly payments under a 10-year repayment term will be $368 instead of $311 ($57 higher) and the total payments over the life of the loan will be $2,369 higher as compared with a borrower who pays the interest during the in-school and grace periods. That’s 8.8% of the amount originally borrowed. On a 20-year term the total payments are $4,614 higher and on a 30-year term the total payments are $7,177 higher.</p>
<p>An independent student who borrows the maximum amount of Federal unsubsidized Stafford loans will have a balance of $53,325 upon entering repayment at the end of the grace period. This is $8,325 (18.5%) higher than the $45,000 borrowed. The monthly payments under a 10-year repayment term will be $614 instead of $518 ($96 higher) and the total payments over the life of the loan will be $3,966 higher as compared with a borrower who pays the interest during the in-school and grace periods. That’s 8.8% of the amount originally borrowed. On a 20-year term the total payments are $7,721 higher and on a 30-year term the total payments are $12,007 higher.</p>
<p>Thus deferring the interest during the in-school and grace period increases the loan balance at repayment by about 18.5% and the total payments over the life of a 10-year loan by 8.8% of the amount originally borrowed. On a 20-year term the total payments increase by 17.2% of the amount originally borrowed and on a 30-year term the total payments increase by 26.7% of the amount originally borrowed.</p>
<p>On Federal PLUS loans and private student loans the added cost of deferring the interest is even higher due to the higher interest rates.</p>
