Retirement Planning with Replit
Retirement planning shouldn't feel like rocket science.
So I built an app to make it simple.

I do a lot of retirement planning in my spare time and it used to feel like a maze of spreadsheets.
Most online calculators (Nerdwallet, Bankrate) are a great first step but don’t take into account fundamental assumptions for future value (401k match, taxes on Roth contributions, or any withdrawal strategy besides the 4% rule).
I built a retirement planning app using Replit to simplify the process and provide clear, visual projections based on user input.
As a PM, I strongly believe in building apps that have utility.
Thanks to Replit I finally retired my Excel spreadsheet.
Say goodbye old friend 👋
What is Replit?
Replit is an AI-assisted IDE that lets users code, build, and deploy applications directly from their browser with prompting.
It provides a dev environment complete with client, server, and database capabilities that you can deploy to cloud-hosted environments.
It features an autonomous AI agent and an AI assistant to help users build.
Replit’s Agentic AI enhanced my one-liner with BE logic and FE styling requirements.
But it performs better when you provide a PRD.
I provided a list of default values, and it assumed that I would withdraw from my savings account before withdrawing from my 401k in retirement.
Didn’t even tell it to do that, which was awesome!
It also calculated the shortfall and laddered the tax rate increases over time.
Next Steps
Planned enhancements:
Adding support for Roth 401k and IRA accounts.
Incorporating Social Security benefits into projections.
