Calcualtion help  David  03082004 This is what I am trying to accomplish:
CST = Cost of the equipment. PMT = monthly payment. I%YR = the interest rate I am buying my money at. RV% = This is always a negative # and is used when a balloon is due at the end of the term (10% is a typical buy out). N = the length of the term in months. #ADV = number of advances (due to the time value of money this could increase my profitability on a deal substantially). PTS = The amount of money I would like to make on a deal i.e. 10 points on a $20,000.00 deal would = $2,000.00 of gross margin. There used to be 2 pages to this equation which resulted in a "more" tab. Re: Calcualtion help  Eddie Shore  03082004 Depends on what calculator are you using. If you are using the HP17/19 Series, there will be a MORE option. If you are using the 48/49 Series, you will not see a MORE box (just press NEXT to go to page 2).
Re: Calcualtion help  David  03082004 Thanks for the response Eddie. It's a 17B II and I am in need of the calcuation to input. I deleted it accidentally changing batteries and the formula burned to the ground along with my house.
Re: Calcualtion help  Wayne Brown  03082004 David,
What was the original source of this program? I don't have a 17bII myself and don't know anything about programming it, but if this was a published program, I'd be glad to try to help you find a copy. For instance, if it was printed in the manual, I can point you to an electronic (PDF) copy.
Re: Calcualtion help  David  03092004 Wayne, Thanks for your response. It's not in the manual. It was an equation put together by a guy that has long since disappeared. I know what the tabs look like and what I am trying to accomplish but alas I have not found anyone to help with the following need: CST = Cost of the equipment. PMT = monthly payment. I%YR = the interest rate I am buying my money at. RV% = This is always a negative # and is used when a balloon is due at the end of the term (10% is a typical buy out). N = the length of the term in months. #ADV = number of advances (due to the time value of money this could increase my profitability on a deal substantially). PTS = The amount of money I would like to make on a deal i.e. 10 points on a $20,000.00 deal would = $2,000.00 of gross margin. There used to be 2 pages to this equation which resulted in a "more" tab.
I am willing to pay for this. I am in desperate need.

Will SOMEone PLEASE fix the spelling of "Calculation"?  Paul Brogger  03092004 ;^)
Calculation  Bob Wang  03092004 OK, I can't spell. Probably can't "calcualte" either ;) But I think David is looking for something like:
ADV: PMT=( (1+PTS÷100) × PV – (RV%÷100)×FV × (SPPV ( I%YR ÷ 12 : N ) ) ) ÷ (USPV ( I%YR ÷ 12 : N  #ADV) + #ADV)
Re: Calculation  Bob Wang  03092004 Yup, already saw one mistake. PV should be CST.

Use this at your own peril!
Bob Wang  David  03172004 Is the master of the Universe. Thank you soooooo much for the formula. You are a life saver.
