Minafi's Take on MUB vs TRFFX

Here's an in depth look at the differences between iShares National Muni Bond ETF ($MUB) and T. Rowe Price Target 2055 Fund ($TRFFX).

To start off, here's a look at the basics of each fund. Keep an eye on the FI Score. That's a custom score from 0 to 100 that we generate based on how good this fund is for the casual investor. Most investors only need a handful of total funds in their portfolio. The higher the score, the more likely this is one of those few. Score alone isn't enough! Keep reading on to see how different (or perhaps similar) these two funds are.

$MUB is classified as an ETF while $TRFFX is classified as a Mutual Fund. Even though one of these is a mutual fund and the other is an ETF, that doesn't matter too much for their holdings. Both ETFs and mutual funds are just containers to hold lots of investments inside of them.

The biggest differences between these two is where they may be offered. ETFs are more widely availble from a larger number of investment apps and websites. Mutual funds, on the other hand, are generally offered by the platform they're issued by (Fidelity funds on Fidelity, Vanguard funds on Vanguard). Usually 401(k)'s will offer both ETFs and Mutual Funds. If you're investing outside of a 401(k), I'd recommend you verify the fees associated with ETF and mutual fund transactions. Some platforms charge an additional fee to purchase a mutual fund.

When evaluating a fund, the first things I look at are:

  • What it invests in
  • How much it charges in fees
  • How large the fund is

Let's look into these criteria one by one and see if either of these funds stands out.

Fund Holdings Comparison

Minafi's FI Score algorithm takes into account the category and market. The more niche a fund is, the lower the score. This doesn't mean it's a worse fund, but it does mean you should stop and make sure this a fund you need to diversify your portfolio.

MUB TRFFX
Market Score 9.9 /10 2.9 /10
Category Score 8.0 /10 5.0 /10
Total 17.9 7.9

A score of 10 means this is a solid market and category that almost every investor will want to have investments in. The lower the score, the more specific the investment. These scores are based on when most investors would add these funds to their portfolio. A score of 10 means that this fund (or one like it) belongs in a three-fund portfolio. The lower the score, the farther down in your portfolio a fund would go.

Winner: $MUB

Fee Comparison

Fees are one of the biggest killers of portfolio growth. The difference between a 2% fee and a 0.04% fee over 30 years can result in your portfolio having half the total value!

If you're just getting started investing and learning how fees impact your portfolio, I'd encourage you to read through my free investment course (specifically '2.2 - All About Fees') where I go over all the different types of fees you can be charged and how to lower them.

For these two funds, MUB has an expense ratio of 0.07% while TRFFX has an expense ratio of 0.17%. In this case, both of these funds have a similar fee.

Winner: $MUB (barely)

Fund Size Comparison

One place these two funds differ is in their total assets under management. This is a good indication of how many other investors trust this fund. A large fund by itself doesn't mean it's a good fund, but it is one thing to consider when figuring out how to choose the right fund.

In the case of these two funds, MUB is a large fund with 16.3 Billion in assets under management. TRFFX, on the other hand, is a small fund with 82.2 Million in assets under management.

Which Should You Choose? MUB or TRFFX?

Comparing these two funds isn't an apples to apples comparison. MUB is a Bond Municipal Bond fund, while TRFFX is a Allocation Target-Date fund.

If you're aiming to build a diversified, low-fee, tax-optimized portfolio you likely won't be choosing between these two funds since they're different enough.

Running both of these funds through Minafi's FI Score algorithm, gives MUB a score of 95 and TRFFX a score of 58.
