Savings Account, Money Market, & Treasury Comparison

[RonSwanson1776]

I've been saving for a down payment and was frustrated at the lack of ability to quickly compare Savings, Money Market, and Treasury rates of return.

https://yieldfinder.app/

It isn't perfect, but I made a tool that is semi-automated (I run the script locally now, but should be able to automate this relatively easily) to compare the rates of return. There are a couple of things I'm working on, but would love any feedback/suggestions.

Rates by product:
Banks -> Savings APY
MM -> 7 day yield
Treasuries -> Interpolated rate

These rates aren't directly comparable, but are close enough to make an informed decision IMO. Please let me know what feedback you have!

Could you add FZDXX and FDLXX?

Curious about how you are retrieving Bank rates, the tool I produced already addresses MM and T-bills.

Don't know if you have seen: MM Optimizer

https://moneymarket.fun could be a good source for you to retrieve a more general set of money market funds.

Will look into adding them. Thank you!

Yes. Huge fan of both tools. I didn’t want to rely on another site for information so choose to pull from sources directly rather than leveraging money market.fun.

The bank rates are scraped daily (or whenever I run the script rather). It was a pain, but I have a method that works reliably at this point.

So I am a shameless user of other peoples work (that is what I love about software).

Do you mind if I farm/scrape the JSON string embedded in your app for savings accounts? If you can reasonably keep up your updates, I can import that string into my infrastructure and add a page about Bank rates. I have Treasuries and MM funds pretty well covered. Vanguard/Fidelity directly and the rest via @adamhg's tool.

Also, not sure what your development environment looks like, but I can share some schemes I have been using to automate to a degree without paying for commercial services.

If interested, PM me and we can coordinate. I have a Github that is starting to take shape to encourage cooperative efforts.

Yes of course, sent you a DM

For you posters who are able to construct these tools … Do you have any leads for me on someone I can hire to do some scraping of data and creation of simple programs analyzing that data ? I have the data readily available and it has an API key. Could be US or international based (our son who is in tech in Asia, is seeing if there are resources there that might help me). It’s not a lot of heavy lifting for someone with the skill set.

PM me, if you are serious. There are tons of services out there that will sell you a programmer for hire, I am not currently up on those. Someone else can chime in. At one time Amazon had a Mechanical Turk service that was a marketplace for buying commodity programming services. I have no idea if it is currently viable.

Now that Fidelity Cash Management will allow you to change your default to SPAXX, YieldFinder is out of date.

Cute tool.

It still shows VUSXX Vanguard Treasury Money Market Fund has the top yield for California residents.

One thing I have noticed is that once one gets well over the NIIT limit, the effective marginal Federal Tax of 24% becomes 27.8%.

[retiringwhen]

Correct, often missed.

It automatically defaults into the sweep program so I think I'm going to keep it as is, but you can see the rate for SPAXX listed under money markets!

I've had success using Upwork in the past, but I would consider trying to use chatgpt or Claude on your own! If you can articulate what you want to do/see in plaintalk, it can usually help you translate it into code.

i suggest that you will get a more useful answer if you calculate the after tax return on these instruments; the idea is that income from treasuries are exempt from state income tax, while income from the other instruments are taxable by states.
