# simulink-moneyflow-library

This is a Simulink® library consisting of:

-) A block modeling a bank account that earns interest after each period -) A block that calculates US federal taxes according to a given tax bracket

Four examples are given:

1. how to use the tax block (tax_block_example.mdl)

2. how to use the bank account block (bank_block_example.mdl)

3. how to calculate money flowing from paycheck to retirement and bank accounts, during employment years (ContributionFlow.mdl)

4. how to calculate money flowing from retirement and bank accounts (and social security) to expenses, during retirement years (DistributionFlow.mdl)

The last two examples can be useful for retirement planning. For example, they can be used to suggest preliminary answers to questions such as: -) how much money do I need to save for retirement? -) how long will my savings last during retirement? -) should I prefer tax deferred or after-tax (roth) 401K accounts? -) how do I to minimize cumulative taxes over a lifetime?

An additional folder contains:

-) A MATLAB® function (taxes.m) that uses a different (and completely independent) method to calulate taxes from the block in the library -) A Simulink model (block_vs_mfcn.mdl) that compares the tax block and taxes.m for positive values, showing that they are indeed equivalent

-) A MATLAB function (mort.m) to calculate mortgage or bond dividends -) A MATLAB function (bond.m) to calculate discounted bond values -) A MATLAB function (irate.m) to calculate monthly, daily and continuously compounding interest rates equivalent to a given yearly compounding rate

The last 3 functions are inspired by (and use the same notation of) the book "The Math of Money: Making Mathematical Sense of Your Personal Finances" from Morton D.Davis: https://www.amazon.com/Math-Money-Mathematical-Personal-Finances/dp/0387950788
