Join the conversation. Tell me what you think.
Jan says:
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
Karl says:
Yes you can. Please use the Ultimate Financial Calculator
If you scroll down the page, you’ll see a series of calculation tutorials. I suggest that everyone works through tutorial #1 for some basic information.
After that, this tutorial is for your specific use case:
25. Calculate Loan Balance — Loan Payoff Calculation
Enter payments for any amount on date made — audit balance due
Pamela says:
Are your downloads compatible with Mac’s? Can you give step by step instructions?
Karl says:
Sorry, but the downloads are only for Windows PCs.
brownbrady says:
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?
Karl says:
No, sorry, there isn’t one. But it sounds like adding one would be a really good idea.
inezstorage says:
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.
Karl says:
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.
