Morty Mortgage for just
(Ten US Dollars). This trial version will operate for 14 days. If you purchase the program I will send you a serial number by email that will enable continued operation with no time limit and remove the exit nag screen. Pay once and all future upgrades are free. Your serial number will work with all future versions. This demo version is fully functional. No features have been removed. It contains no spyware, no advertising.
To change the input values click the up/down arrow on the right side of each input box:
Each time you click the number changes by one increment and the entire table is recalculated.
The program saves and restores the increments for each value the next time it is run.
There are 6 variables you can enter:
- The simple uncompounded interest rate of the loan. This number is usually given by the bank. The program uses this number to calculate the APY (Annual Percentage Yield) which is the compounded interest rate. Values from 0.0001 to 99.9999 are allowed with up to 4 decimal places to the right of the decimal point.
- The total amount of the loan. This may be in any currency such as Dollars or Euros. Values from 1 to 1 trillion are allowed.
- The number of years in the loan. Must be a whole integer number. Partial or fractional years are not allowed. Values from 1 to 99 are allowed.
- The date the loan begins. The first payment is due 1 month after this date. Click on the down arrow to display a selection calendar. Loans may begin on any day of the year. A loan begun on the 31st will have a payment due on the last day of the month in months with fewer than 31 days. Leap years are included and calculated as required.
- This value is optional. Most loans have a zero extra payment. This is an extra amount you would include with each payment of the loan. It allows you to pay off the loan faster. If you include an extra payment the length of the loan is automatically shortened. For example, an extra payment of just $30 per month might allow a 30 year mortgage to be paid off in 28 years. The extra payment must be less than the total principal amount of the loan.
- This value is optional. Most loans have a zero balloon payment. A
is a one-time payment you must make at the very end of the loan. The balloon payment must be less than the total principal amount of the loan.
The next time you start Morty it will remember which columns are on and off, column locations, and column widths.

I am PayPal Verified. My Account Creation Date is May 30, 2000.
The Official PayPal Verified Seal above means that I have provided PayPal with proof that I have a bank account and that my address is valid. Banks are required by law to screen account holders so PayPal's verification process increases security when you pay parties you do not know. My bank has my address and Social Security number on file. I have been using PayPal for over 16 years.
I use PayPal because the fees are low. If you send me $10.00 PayPal only takes about $1.00 so I net $9.00. All other payment services take several dollars so I would have to charge around $15 for my program to gain the same net. This lowers the cost to you. PayPal does not charge you any fees. PayPal is also free for me for most purchases, such as Ebay auction payments, but as a seller I am required to have a Premier Account with fees. If you do not have a PayPal account, you can still use PayPal to make a payment using your credit card. PayPal does not charge you any fees for this. PayPal is a very secure and reliable payment system used by millions of people around the world.
