Re: Show HN: I made a simulator for personal finance and financial independence
#2I had trouble finding a good FI planning and simulation tool that could model things in enough detail to finally ditch my spreadsheets... so I decided to build one: ProjectiFi
A while back I posted a very early version here (https://news.ycombinator.com/item?id=26969173), and just released a major overhaul with loads of new features and enhancements, many inspired by the initial HN commentary:
- Monte Carlo mode with customizable simulations, variables, probability distributions
- Backtesting on historical data
- Multiple data persistence options for subscribers: cloud synchronization, localStorage only, or manual import/export
- Stock/bond allocation curve over time
- Improved support for international use cases (currency + locale selector, custom options and contribution limits for financial goals)
- Ability to quickly switch between deterministic and probabilistic modes
- Many new event types to model a broader range of scenarios
- Better support for married filing jointly / couples planning (perhaps still not perfect, but definitely better)
- Redesigned landing page, additional UI improvements
- And more!
If you feel like checking it out, I would love to hear what you think. Most of the functionality is free, but for anyone interested in upgrading to Premium, you can use coupon code "HN-15" for 15% off all plans :)

#3Congrats. Remember trying this out on your previous post and it wasn't that UK friendly, sounds like that should be better minus the Tax features so will try again.

#4Looks great! I like that there is a FREE tier - thank you!
I recently wanted to run some simple simulations (mortgage & investments) so I wrote a simple JS script that outputs the amortization table and a graph in the terminal of multiple scenarios you want to compare. Very limited in scope, but might be useful to others:

Thanks, I'll be interested to hear what you think of the new version. And if you have further ideas/suggestions to continue improving/generalizing things for international use cases, just let me know!

#6Thanks! I understand that is not your purpose now, but do you plan to extending to businesses? I'd be glad to have such decision helping tool :).
Also, congrats for your website. I find it very clear to understand what the tool does, why it is useful (your example are simple and to the point), and what is your pricing. :+1:

Extending the tool to accommodate planning for businesses sounds like an interesting prospect, though I'll be the first to admit I know less about the nuances there than in the personal finance domain. I'll take a note to do some more research in this direction, and if you have any further thoughts/suggestions on what kind of new features would be needed to accommodate use cases like that, I'd be all ears!

Thanks Colin! Really appreciate the subscription :)

#10I gave a quick try and just from the first look this looks amazing. It's precisely what I'm missing in my spreadsheets for my personal finance: probabilistic planning. I'd consider paying the premium tier but I miss a few things:
- Support for tax brackets in other countries (maybe let users introduce them manually)
- Support for "disasters" in the probabilistic case. I'd be interested in knowing how robust is my strategy to being fired, or having a reduced salary. For example, letting me input a "probability of losing employment" per year and possible ranges for time being unemployed would be interesting.
- Also, support for variable-rate mortgages would be interesting. Here in Spain there are quite a lot of offers on mortgages at X% + euribor, and it'd be interesting to put together the behaviour of the mortgage index and the investments. Related with the previous points, simulation of economic crisis could be interesting: investments go down, increased probability of losing my job, increased mortgage payments maybe... Do I survive those crisis? What's my margin?
All in all, pretty interesting, congratulations on the job.
