Answer

The monthly payments necessary on this loan is equal to \$187.57

Work Step by Step

Loan calculations are identical to annuity calculations, so: The formula for the payment value for a loan is: $PMT = PV\frac{i}{1-(1+i)^{-n}}$ Where: $PV= 10,000$ ** The withdrawals are made monthly (12 times per year), so m = 12. $i=r/m=\frac{0.0475}{12}$ $n=mt=12 \times 5=60$ Therefore: $PMT = (10,000)\frac{\frac{0.0475}{12}}{1-(1+\frac{0.0475}{12})^{-60}} = 187.57$
