Interest Rate Options - Effective Loan amount with Calls vs. Puts 
| This is something that hurt me in Sample 2. 
 With regard to interest rate options, why, when calculating the base amount off which the effective interest rate will be computed, do you ADD the cost of puts and SUBTRACT the cost of calls?
 
 For example, if you have a loan to be made in 30 days on $1,000,000, you would calculate the FV of a call option you want to buy and subtract it from 1,000,000. The opposite is true with a put, you would calculate the FV and ADD it to the 1,000,000.
 
 I don't understand this at all. Any help is appreciated.
