I agree with this. Inflation is a huge factor and needs to be considered with any retirement calculator because you can't assume that your $100K today is worth $100K in 20 years.

I actually built a calculator myself to better accommodate for inflation and have the ability to tweak the numbers just a bit more. If you're interested:

Huh. Crazy how close it is to my implementation - https://modelinvesting.com/retirement-calculator/

You have a UI bug on your tooltips on advanced fields. They show up way above where they should be =)

Awesome tool! I honestly feel like the more of these there are in the world, the better. So many opportunities to help people learn more about investing, saving, etc.

I know that's a bug I need to fix, something with bootstrap. Thanks for pointing it out and hopefully will have a fix tonight!

Thank you! I have a ton of fun doing the development for that site, calculators and all. Definitely one of my flagship products over the years, great client -> great product =)

Hey Folkhack. Nice to see you on this thread. I posted a link to my retirement calculator here too. It was always fun discussing design with you.

[peterangular]

Eyyy asaph - was good to see you in here too! Always down to chat design. Stop by again if you're ever in the neighborhood!

Why is there a minimum amount on the field for how much you need? i.e. if I make $500k now, why am I forced to spend $100k in retirement? What if I only need to spend $50k?

[AustinGrandt]

I think if you look in the advanced fields you can change to how much you need in retirement to set a separate number. We auto calculate and extrapolate based on current savings rate, but a lot of people will spend much less in retirement.

Just fill out the field income in retirement under advanced fields and I think that should (hopefully) be what you're looking for.
