PCalc 2.0
PCalc is an additional payment calculator for a loan. You can evaluate various scenarios for making additional payments to minimize the total sum of interests and to estimate the real cost of your next "big buy".

With PCalc you will get a payment schedule for your loan as well as a total sum of interests. Then you can insert into your schedule any number of additional payments with any amount and date each of them. You will see how the total sum of interests changes due to those additional payments. You can evaluate various scenarios for making additional payments to minimize the total sum of interests you have to pay in accordance with the future available income.

PCalc will allow you to estimate the real cost of your next "big buy". For example, for a loan of $250,000 for 30 years with 6.5% annual interest rate PCalc shows that if you pay $1000 every month as an additional payment and skip the third month additional payment your total sum of interests will increase by $600 (six hundred). This means that your big buy worth of $1000 during the third month will really cost you $1,600. It is a bitter truth but it is an actual truth.

With PCalc you can integrate your payment schedule into another calculations as easy as Excel allows.
