FIRE_simulation

v1.0

20200618

A personal finance simulation to predict retirement date.

with some adjustable variables, and some probabilistic variables, you can run a simulation of 500 clones of yourself pre->post FIRE and see how many clones retire at what years.

Some clones get lucky with the market and eg low child costs -> retire early.

Some clones get bad luck and take a few more years to retire!

can also track a clones assets, income, savings rate over time.

Also can use to stress-test (eg poor market returns), and goal seek (assets go to zero when i die. to retire earlier)

Top right are variables about me.

Top left are market variables.

bottom right are simulant/clone (output) info.

Middle 'folder' represents a clone of me.

some vars arent fixed, rather probabilities eg child costs being unknown, i have normally distributed it (my half of costs) around $12k pa and each clone of me gets a random cost on the dist for the simulation. I will add and update in next version

Sign up to insightmaker, click "clone insight" and build/adjust your own modelling. Or send feedback to phillip.balding@gmail.com

programming notes:

-market return years running consecutively not random.

-future years return FIRE rule

-cap_gains and pay_super flows can now be neg

-intro of super still seems too high, grows too much after 60

-rearrange user input variables

To do:

-get actual historical dividends

-goalseek to die with 0 assets -> minimise retirement age.

-year begin not integer?

-auto interpolation seems good.

-tidy the fucking model map mess

-fix child costs at initial random dist.

This model is a representation of a predator prey dynamic between natural capital and built capital in relation to tourism.

Model of tourism

JP Burklow

The Lotka-Volterra equations (also known as the predator-prey equations) model the dynamic interactions between two biological populations: a predator and its prey.

This form of modeling dynamic systems is based on "stocks" (amounts) and "flows" (rates of change). For the predator-prey model we ask what factors impact the flows (the thick arrows) into and out of the populations of sheep and wolves (the stocks)? The dotted arrows can be used to connect and describe the relationships within the model. Additional variables, e.g, sheep fertility, can be added to the model to make relations clearer.

Overall, the dynamics for this kind of modeling centers on the factors that impact the flows. Click on any of the flow-arrows to see how the factors connect by the dotted arrows are used to determine the flows in or out of the stocks (the populations).
