Im currently with Fidelity for the past 8 years at current job, new employer has ADP.
I feel like I will be losing money if I rollover the money in the account to new employers plan. Am I thinking of it wrong, as I put money into these different funds when they were less expensive and now if I bought back in at a similar fund i would have less shares. It seems to me like I would be losing the future growth, any help understanding this any deeper would be appreciated

Here is a ChatGPT answer to your question.

This is a very common and very reasonable concern, and the good news is: you’re not actually losing money or future growth just by rolling over. What you’re thinking about (buying back in at higher prices and having fewer shares) feels like a loss, but economically it isn’t. Let’s break it down carefully.

The core misconception (totally normal)

“I bought these funds at lower prices. If I sell and rebuy now, I’ll have fewer shares, so I’m losing future growth.”

Key truth:
?? What matters is the dollar value invested and the future return, not how many shares you own.

If you have:
$200,000 invested
And the market goes up 10%
You end up with $220,000, whether that $200,000 is:
2,000 shares at $100, or
1,000 shares at $200

Shares are just units of measurement.

What actually happens in a 401(k) rollover
Step-by-step reality:
Your Fidelity 401(k) investments are sold
The money moves tax-free (if done as a direct rollover)
You reinvest the full dollar amount in the ADP plan

If:
You had $180,000 at Fidelity
You roll it over
You reinvest $180,000 at ADP
?? You still have $180,000 working for you in the market

No value disappears.

Why future growth is NOT lost

Let’s use an example:
Before rollover
1,500 shares of Fund A
Price = $100
Total value = $150,000
After rollover
Fund B (very similar index)
Price = $150

You buy 1,000 shares
Total value = $150,000

Now suppose both funds grow 8% per year.

Scenario Value in 10 years
Stay at Fidelity ~$323,000
Roll to ADP ~$323,000

Same math. Same growth.

When rolling over can actually hurt (real risks)

This is where your intuition is smart — but for different reasons.

?? Potential downsides:

Higher expense ratios
Some employer plans have expensive funds
A 0.75% fee vs 0.05% fee is a real drag over time
Poor fund choices
Limited index options
Heavy use of actively managed funds
Being out of the market too long
If the rollover sits in cash for weeks during a rally
(This is avoidable with proper timing)

Often the best option people overlook
? Leave the money at Fidelity (if allowed)

If:
Fidelity plan has low-cost index funds
No maintenance fees for ex-employees
You like the investment options
Then you can:
Leave it exactly where it is
Keep all your current investments
Roll it later into:
An IRA
A future employer plan with better options
No rule says you must move it now.

Another strong option (often best long-term)
? Roll Fidelity 401(k) ? Fidelity Rollover IRA

Benefits:
No taxes
No forced fund changes
Full control (VTI, SCHG, VXUS, etc. — aligns with how you already invest)
Usually lower fees than employer plans

Downside:
If you plan backdoor Roth conversions later, this can complicate things
(happy to explain if relevant)

How to decide (simple checklist)

Ask these questions:
Fidelity plan
What are the expense ratios?
Any admin fees after leaving?
Good index options?

ADP plan
Cheapest S&P 500 / Total Market fund?
Expense ratios?
Any employer match vesting rules?
?? Fees and fund quality matter far more than share count.

Bottom line (important)
You are not wrong to be cautious — but the fear about “losing future growth due to fewer shares” is a mental accounting trap, not a real loss.
You only lose money if:
You pay higher fees
You’re forced into worse investments
You’re out of the market too long

you won't, assume it happens instantaneously, you will sell 100 shares of x and buy 100 shares of y.

But like the other person said, you should roll over to an IRA on a platform like fidelity and then thats where you roll over any 401ks when you leave a job

Agree. That way there are no fees associated with the old 401k and you aren’t limited by their investment options.

How old are you? If age 55 is on the horizon, you might want to google "Rule of 55 401K" and read up. If you leave a job during or after the year you turn 55, you can immediately access your 401K without penalty. You can only access the 401K from the job you left, not an old one, and you can't do this with an IRA, only a 401K. It is worth considering when deciding whether to roll over to an IRA or a new employer's 401K, but you can always rollover from a rollover IRA to a 401K if that IRA only contains rollover assets from previous 401K's.

Roll into IRA.

IF you wait, you may have some hassle transferring a bigger account.

I had to find a medallion signature to transfer my money from 403b and 457 to my Traditional IRA when I retired.

It took a couple of times because the banker signature could only do $500,000 at a time. These were accounts where I worked for almost 10 years, and where I had rolled over another account to.

I’m down to a traditional, a Roth, and a SEP now. Will roll the SEP to traditional when I stop my business(small)

Rollover to an IRA, not the new 401k.

Then put it in the place that gives you the most opportunity to grow it, but keep in mind as you get older that you might just realize that work sucks by the time you are 55.

That’s not how this works. You cannot roll your money into your new employers 401(k) plan. You will roll your money into an independent IRA.

This is actually one of my favorite things about changing jobs. You get to roll your money into an IRA tax-free, and the IRA will give you substantially more control over how you invest the money than your employer sponsored 401(k) program. You will be able to purchase the full range of stocks, ETF, and mutual funds, not just the ones that are included in your program.

That’s not true for many employer plans.

This /\.
Roll over the old job 401K into a Self Directed IRA and keep in Fidelity. Fidelity can help you do this and will handle the transaction so that you don't acquire any tax burden. You'll then be able to select from all the investment options that Fidelity has to offer.
You'll start a new 401K with your new company. Delete the old company 401K with it being replaced by your new Self Directed IRA.

Most of the time you can but as the thread has shown most would advise not to. The one exception is if you need to utilize the Rule of 55 at the new employer.

I was unaware of that. But even if you can, why would you? It’s such an advantage to have the freedom to invest your portfolio.
