AI Thread Summary
To generate a complex loan amortization schedule for a $390,000 loan with three annual payments of $10,000 each, starting on July 5, 2015, and amortized over 30 years, an interest rate must be specified. A suggested annual interest rate is approximately 6.5%, assuming total annual payments of $30,000. The irregular payment dates complicate the use of standard formulas for amortization. A computer program or spreadsheet is recommended to accurately calculate and print the amortization schedule. Providing the interest rate will enable more precise assistance with the calculations.

How would I create a complex loan ammortization schedule for the following figures

$390,000 Loan

(3) payments of $10,000 each year on Jan 5th, July 5th and Oct 5th

First Payment on July 5th 2015

Ammortized over 30yrs

Hi dzweber! Welcome to MHB! (Smile)

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?
 
Not even sure where to start with a formula. Hoping for a spreadsheet referal

Problem: you didn't specify an interest rate

Anyway, assuming an annual payment of 30,000,
an annual rate of ~6.5% needs to be the loan's rate.

But regardless of all that, no formula can be used
using those weird payment dates.

If you need an amortization schedule, then you need a
computer program to do the calculations and appropriate
schedule printing.

I'll gladly help...once you supply a rate!
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
For original Zeta function, ζ(s)=1+1/2^s+1/3^s+1/4^s+... =1+e^(-sln2)+e^(-sln3)+e^(-sln4)+... , Re(s)>1 If we regards it as some function got from Laplace transformation, and let this real function be ζ(x), that means L[ζ(x)]=ζ(s), then: ζ(x)=L^-1[ζ(s)]=δ(x)+δ(x-ln2)+δ(x-ln3)+δ(x-ln4)+... , this represents a series of Dirac delta functions at the points of x=0, ln2, ln3, ln4, ... , It may be still difficult to understand what ζ(x) means, but once it is integrated, the truth is clear...
