financial online calculator Join the conversation. Tell me what you think.
  • I am working on a loan an individual (friend) made to his son for business purposes. The loan I guess was made in advances of 3 or 4 amounts starting in 2008. payments started being made in Jan. 2010. My friend wants to charge 5.5% interest and recoup the loan funds in 20 years.
    I’m trying to put together an amortization schedule after the fact.
    I have a record of the payments made of which there approx. 80 payments received in the amount of $2,000.00 practically every month.
    Can I re-create this scenario now in 2016?
    Thank You, Jan 8037578269

  • Is there a TFSA “Catch-Up” calculator to determine the date when a TFSA’s contribution room will be maxed given the current balance, new contributions, and new room created each year?

  • I paid $69 for this, and I’m not sure it’s what I’m looking for: First of all, where is the phone number so I can call? Where do I find the irregular amortization schedule for a loan? I pay different amounts at different times of the month, and that’s what I need to calculate.

    • I’m the sole owner and employee of the business and I’m hearing impaired, so I can’t offer affective phone support any longer.

      The best calculator to use is the C-Value! Classic calculator, accessible from the Schedule menu at the top.

      It will allow you to track payments made on any date. There is a tutorial or user guide that describes how to do this. Please see tutorial #25 in the program’s "Help."

      If you don’t see it in Help, then this online tutorial will work too.
