"In order to get a good understanding of the purchasing power of your future retirement savings for today, you can do a “simple” calculation: Take your total retirement savings and multiply it by 3%. For example, if you have $1.25m (retirement savings), multiplied by 0.03% (inflation), you get $45,000 in inflation. Then you subtract that number from your total savings: $1.25m - $45k = $880k. This will give you a base…

also $1.25MM x 3% = $37.5k

Not $45k

It is difficult to trust the calculator when arithmetic errors exist in the prose.

I love "retirement end year" in this...aka death.

I can certainly picture the dev frowning at the screen trying to think of a way of not just saying "bucket kicking date".

Yowzers! Please tell me what this magical investment is where I can expect an average rate of return of 9% (let alone 12%). That is off the charts optimistic.

You can get guaranteed 11% returns at https://www.twino.eu/ I used it for a while; it did work and their published financials are solid, but being happy with some risk I decided stocks where a better play. Still, it's a useful baseline.

tino shows a default or delayed rate of around 25%. That means your returns are not risk free.

You desperately need to grab someone from the street and see if he knows what he's looking at. The UI is not very intuitive, or you have specific target audience.

- Age range input. It took me a minute to understand what this is for. I assume the lower bound is my current age and the upper bound is the retirement age

- How much do you currently have saved? ex $1,000. I actually tried to type a dollar symbol and nothing happened.

- Aggressive vs conservative. Huh? What are you talking about? What is aggressive/conservative?

The list goes on...

Yep. Such as .03% vs 3%.

> there's no way I'm going to have saved enough money to live off of It is possible. It will take work and change on your part. The first step is to track your spending. The easiest way to do this is get an account with mint, ynab (you need a budget), or personal capital. You can link all of your accounts with the site and app. You can then categorized your spending. After you do this you can start seeing where you c…

There is no straightforward risk-less formula, unfortunately. You can follow all the textbook advice, have a budget, max your 401k, pay down your debt, buy a house, blah blah blah, and after 20 years still only have 1x or 1.5x your salary in total savings [ask me how I know] due to bad luck, unfortunate market timing, lack of skill in investing, emergencies, etc. I hate all this simplified, incomplete advice. If succ…

Amen! I read The Millionaire Next Door when I was 22. Bought a house in a low-cost but appreciating neighborhood. Started working with an accredited financial advisor. Saved double-digit percentages of my income. Worked hard, made a six-figure income.

At forty? Here I am tens of thousands in debt, all that hard work gone. I did all the things society told me to do if I wanted to live the good life, but life can come at you in unexpected ways. For some people it is poor health, others a crazy ex and a truly unfair divorce. Businesses succeed, but sometimes they also fail.

Much like the founding story myth discussion here on HN, we might do well to hear some stories of personal financial failure as vehicles for learning.
