Retirement is a mysterious target that exist out in the future. I better get it right since I only get one shot at it. There are some prerequisites like savings, investing, and drawdown strategy that needs to be firmed up for a successful execution of a retirement plan.

The Withdrawl Strategy

A successful withdrawl strategy will allow for withdrawal from your pool of assets without ever depleting the assets prior to your death. There are positive value to your assets at death is a successful retirement, and the flip side of no assets and still alive is a failure. The most common methodology is the 4% withdrawal rate as published by the trinity study. To have a successful retirement you need:

Your expenses and taxes to be within the 4% threshold or less.
When the markets fluctuate, like the big crashes in 2020, you need to withdraw less and keep the expenses within this lowered withdrawal.
Your fixed expenses needs to be well managed to address any sequence of return risks.

Ramit Sethi's Conscious Spending Plan (CSP) model often talks about the parameters of spend as a percent of take home pay:

Fixed Costs = 50% to 60%
Investments = 10%
Savings = 5% to 10%
Guilt Free Spending = 20% to 35%

While the retirement model will have noone in the investment category, i am simply adding it to the guilt free spending in the retirement model.

All of these methods are implying the same thing, it is important to have your fixed costs really low as a percent of your retirement income to have a successful retirement. There is even a broader argument that the longer the retirement time horizon, a lower withdrawal rate of 3.5% or 3% might be more prudent.

Total Retirement Assets Needed To Support Annual Spend
Withdrawal Rate	4.0%	3.5%
Annual spend of $100,000 requires	$2,500,000	$2,857,142
Annual spend of $75,000 requires	$1,875,000	$2,142,857

Reviewing the table above, the differences are very ckear. A $25,000 reduction in annual spend has the impact of $625,000 in your retirement accounts. This equates to several years of working, saving, and investing to account for that extra $25,000 in annual spend.

The spend rate is king! The higher control you have on fixed expenses the higher impact you have towards a successful retirement.

Figured out how to create and display a table to convey information. The table structure in HTML is not the most optimal, but I'm still in the process of keeping everything barebones withing HTML until I'm absolutely sure to introduce a new language or complication.
