DissoWare

by Andrew G. Watters, Esq.

The world's only attorney-programmed family law software suite. Coming soon.

I've been using Mathematica for many years to generate my signature cash flow charts and other materials for trials, but it's extremely tedious. Mathematica is a large, heavy duty desktop application with no web interface. With the recent discontinuation of DissoMaster by the geniuses at Thomson-West, I decided to write my own suite of web-based tools for clients and other counsel to use. I'm not sure what I will get out of this, but having "Andy's Calculator" certified by the Judicial Council would be an ironic result that might be enough for me. Or maybe I make it free with a SMCBA or San Mateo County login and charge per use to the public, with a subscription for other courts. This follows my calendaring program, which I did for internal use at my firm, but which anybody can use for free at the moment. It doesn't have bells and whistles, but this is the kind of thing I can do and that I enjoy doing: link. Any feature requests? Would you prefer essentially a duplicate of DissoMaster as a web application, or is there a better way to do it? PDF generation would be no problem, so I could make it look just like a DissoMaster printout for sure-- or even better. One wish list feature I would have is a set of sliders that adjust the numbers to a target figure in the case of an agreement-- something missing from DissoMaster. And of course, importing DissoMaster files. What else would you find helpful? Feel free to email me.

Time Value of Money with IRR

FV = PV x [ 1 + (i / n) ] ^ (n x t)
PV = FV / [ 1 + (i / n) ] ^ (n x t)

FV = Future Value
PV = Present Value
i = Interest rate/discount rate per year (e.g., 5.0)
n = Number of compounding periods per year
t = Number of years

Enter either FV or PV to solve for the other amount. Once you have FV and PV, you can compute IRR (Internal Rate of Return).






Andy's Calculator (Advanced)

Determine support with tax calculations, bonus income, and other DissoMaster-style features, and print PDF reports.

Cash Flow Analyzer

Input bank statement information and generate graphs.

Output:

Last four digits of account number:

Beginning Balance / Deposits / Withdrawals / Ending Balance
Month 1:  
Month 2:  
Month 3:  
Month 4:  
Month 5:  
Month 6:  
Month 7:  
Month 8:  
Month 9:  
Month 10:
Month 11:
Month 12:

It would also be great to calculate the parametric derivative of the cash flow so that you can see the rate of change of someone's cash flow over time. In Mathematica, you can do that with ParametricNDSolve, but that's going to be tough to implement in Javascript. Also looking forward to adding 3D graphs, courtesy of gnuplot. My dream feature is having people upload the last 12 bank statements and have the program auto-detect the fields and numbers for the CFA, and also generate a heat map of transaction activity. That way if there are any months with unusual amounts of transactions, or transactions above a certain threshold, they would stand out.

Andy's Calculator (Basic)

Calculate support under Family Code sec. 4055.

CS - Child Support
K - Income allocated to support (1+h * 0.12+(800/tn)
HN - High earner's net monthly disposable income
H - Parenting time percentage of the high earner (0.5 by default)
TN - Total net monthly disposable income of both parties
n - Multiplier for number of children (1 kid = 1.0, 2 kids = 1.6, 3 kids = 2.0)
SS - Spousal Support under Santa Clara/San Mateo formula
K = (1 + H)*(0.12 + (800/TN));
CS = n * (K (HN - H (TN)));

Total Net Disposable Income Per Month	K
$0-2,900				0.165 + tn/82,857
$2,901-5,000				0.131 + tn/42,149
$5,001-10,000				0.250
$10,001-15,000				0.10 + 1,499/tn
Over $15,000				0.12 + 1,200/tn

SS - Spousal Support
SS = (0.4*HN) - (0.5*(TN - HN));

Note: Recently updated with the statutory revisions to K, but does not yet
calculate Low Income Adjustment under revised statute that took effect September 1, 2024.
HN - high earner's net monthly disposable income (after tax).
H - parenting time of high earner (0.5 default = 50%).
TN - Total disposable income of both parties (after tax).
Number of kids.
