Our review
Momentum Savings can support a saving routine, but the tools and fee waiver need to fit the way you bank.

Fifth Third Momentum Savings emphasizes goals and automatic saving. Those features can help someone who means to save each month but does not consistently move the money. The account still needs to make financial sense once fees and the ongoing yield are considered. I would compare it as part of an existing Fifth Third relationship rather than assume the word Momentum means higher interest.
Building a habit inside familiar banking
The bank describes opening online, by appointment over the phone or at a branch. It lists identity documents and a camera-enabled phone among online requirements. I would check when the initial deposit becomes available and how external withdrawals work. Automating a checking-to-savings transfer does not establish the speed of an outward transfer to a different bank.
The opening options may be useful to someone who wants help with a first savings account rather than a completely remote experience. That benefit should be evaluated against the actual account costs and the return once savings grow. Automatic transfers can build a habit, but they can also move cash away from checking before a bill is paid if the schedule does not fit income. A predictable fixed transfer after a dependable payday may be easier to manage than a feature the customer cannot explain. The right amount is the one the household can sustain through an ordinary tight month, not the largest amount an app encourages.
Smart Savings can move small amounts from checking, while scheduled transfers provide a more predictable routine. The bank says Smart Savings is managed in the mobile app. I would prefer the method I can understand, monitor and stop when bills are unusually high. A feature that moves money automatically still needs sensible limits.
The fee waiver and the return once savings grow
The current product page states no minimum opening deposit and describes conditional ways to avoid a monthly service charge. Check the applicable checking relationship, minor-owner or military criteria and any funding deadline. Confirm your current standard rate separately from promotions for other Fifth Third products.
A fee waiver connected to checking can make Momentum affordable within an existing relationship, but it should not be mistaken for an extra return. If a saver would keep the qualifying checking account anyway, avoiding the charge can be useful. If the relationship is opened solely to remove a savings fee, the additional account conditions belong in the comparison. The same applies to automatic savings: money moved between a customer's own accounts is still the customer's money, not earnings generated by the feature. Once the reserve is established, the standard yield becomes a more significant part of the account's value than the convenience of moving small amounts automatically.
Service evidence and the Comerica combination
A commercial reader survey included favorable general-bank service comments from Fifth Third customers, but it did not establish the experience for this account. I did not find sufficient product-specific independent evidence to promise easy setup or fast issue resolution. Fifth Third Bank, N.A. is the legal bank. Familiar local staff and deposit insurance may be useful considerations without proving uninterrupted access or future stability.
Fifth Third announced completion of its Comerica merger in February 2026. That is relevant context for customers encountering transition notices or a changing branch relationship, but it does not by itself establish a better savings experience. A larger combined organization is not a promise that a particular branch will remain convenient or that a restriction will be resolved faster. I would follow account-specific transition instructions rather than assume an older Comerica or Fifth Third review describes every current feature. The corporate announcement is evidence of the combination; claims about a seamless customer experience remain something to demonstrate, rather than a benefit to count in advance.
A useful first reserve can evolve
Momentum's automatic saving features are most useful when they fit the household's checking cash flow. With variable income, an amount that feels small after payday can be inconvenient before the next deposit. I would set the transfer around the lowest expected checking balance, rather than choose the largest automatic amount. Once savings accumulate, the account has a second job: earning a competitive ongoing return. Success at helping someone build the first reserve does not establish that it is the best place to keep a much larger one.
I would view Momentum primarily as a tool for building a savings routine alongside banking that already fits. It may serve that purpose well even if it is not where the largest long-term reserve ultimately belongs. There is no need to dismiss a useful habit-building account simply because another bank pays more; there is also no need to leave every accumulated dollar there indefinitely. A deliberate split can preserve familiar bill-paying and automatic saving while moving longer-term cash to a more competitive option. The decision should remain simple enough to maintain, with the interest improvement large enough to justify any extra relationship.
