If you opened a savings account at Cambridge Trust years ago and just checked your statement, the math probably feels off. Local New England banks rarely pay competitive interest, and Cambridge Trust is no exception. The bigger news, though, is that Cambridge Trust merged into Eastern Bank in July 2024, so the rate sheet you remember may not match what is actually posted today.
This guide walks through Cambridge Trust savings account interest rates as they stand in 2026, what changed after the Eastern Bank merger, and how to think about your options if the yield you are earning feels too low to be worth keeping.
What the Eastern Bank merger means for savings rates
Eastern Bankshares completed its merger with Cambridge Bancorp on July 12, 2024. Consumer banking, including checking and savings accounts, now operates under the Eastern Bank brand. The Cambridge Trust name was preserved for private banking and wealth management, but everyday deposit products were moved onto Eastern Bank's systems.
For most depositors, that conversion meant new account terms, a new mobile app, and a new published rate sheet. If you opened a Cambridge Trust savings account before the merger, your current interest rate is whatever Eastern Bank pays on the converted product, not whatever Cambridge Trust used to advertise.
Typical Cambridge Trust and Eastern Bank savings rates
Local and regional banks in Massachusetts almost universally pay below 1% APY on standard savings accounts. Eastern Bank's posted rates on basic savings tiers usually land in the 0.01% to 0.10% APY range, with slightly higher rates on relationship or premier tiers that require larger balances or a linked checking account.
That is a real gap from what online banks pay. As of May 2026, leading online savings accounts pay between 3.80% and 4.20% APY. On a $10,000 balance, the difference between 0.05% and 4.00% is about $395 per year in interest you are leaving on the table.
Why traditional banks pay so little
Brick-and-mortar banks have higher overhead. They run branches, employ tellers, and maintain ATM networks across a footprint. That cost gets paid for somewhere, and historically it has come out of depositor interest.
Online banks skip most of those costs. Without branches, they can hand back a much larger share of what they earn on your deposits. The result is the persistent 3 to 4 percentage point gap between local-bank savings yields and online savings yields.
A higher-APY banking alternative to compare
If you mostly use your savings account as a buffer next to a checking account, Current Banking is one of the more popular online options. With a qualifying direct deposit of $200 or more, members can earn up to 4.00% APY on Savings Pods, get paid up to two days early, and overdraft up to $200 fee-free. There is no monthly fee and no minimum balance.
It is not a one-to-one swap for Cambridge Trust if you genuinely value a local branch you can walk into. But for a savings cushion that mostly sits there, the rate difference is significant.

How to actually evaluate a savings APY
Three things matter more than the headline rate:
- Minimum balance to earn the APY. Some accounts only pay the top rate above $25,000. If your balance is smaller, you may end up at a much lower tier.
- Direct-deposit or activity requirements. A 4.00% APY that requires a $200 monthly direct deposit only works if you can actually meet that.
- FDIC coverage. Standard FDIC insurance is $250,000 per depositor, per insured bank, per ownership category. Online banks and fintechs that partner with sponsor banks should clearly state how coverage applies.
A 0.05% APY is easy to understand because there are no strings. A 4.00% APY may have a few. Read the disclosure once before you switch.
Pairing savings with budgeting
The other half of getting more out of a savings account is knowing what is moving in and out of it. If you have switched banks before, you have probably had the experience of a small recurring charge following you around for months because you forgot to update the card on file.
Monarch Money is a budgeting app that pulls all of your accounts into one view, tracks net worth, and surfaces subscriptions. Firstcard readers get 50% off the first year of the Core plan. It is the kind of tool that makes it easier to see whether a higher APY is actually translating into a bigger balance, or whether the gain is being eaten by spending you did not notice.

Building credit while you save
A savings account is a starting point, but it does not build a credit history. If your score is thin or has dings, the long-term wins (lower mortgage rate, lower car loan rate, lower insurance premiums in some states) come from building credit, not from chasing an extra half percent on a savings yield.
The Self Visa® Credit Card is one of the simplest ways to do that. It is backed by funds you set aside in a paired Self Credit Builder Account, so approval rates are high. On-time activity reports to all three bureaus, and the savings stay yours when you close the account. For a Cambridge Trust customer with cash already parked at a low rate, redirecting a small piece of that into a credit-builder setup can compound much faster than a 0.05% APY ever will.
Should you keep your Cambridge Trust savings account?
A few scenarios where staying put makes sense:
- You actively use Cambridge Trust for wealth management or trust services and the savings account is the cash sleeve of that relationship.
- You want a true local branch for cash deposits and notarizations.
- You have less than a few thousand dollars in savings, where the dollar difference between 0.05% and 4.00% APY is small.
Most everyone else is better off splitting deposits: keep a small operating balance at the local bank if you like the branch, and move the bulk of the savings to a higher-yield online account.
The bottom line
Cambridge Trust savings interest rates today are effectively Eastern Bank's rates, and they sit at the low end of the market for standard savings tiers. The merger gave depositors a bigger institution but did not change the basic economics of brick-and-mortar savings yields. If a few hundred dollars a year in extra interest matters to you, an online savings account is the simplest fix. If you want long-term wealth, pair a savings move with a credit-building habit so that the score lift compounds alongside the cash.
Frequently Asked Questions
Did Cambridge Trust raise its savings interest rates after the Eastern Bank merger?
Most everyday Cambridge Trust savings products were converted to equivalent Eastern Bank products in July 2024. Eastern Bank's posted rates on basic savings tiers are typically below 0.10% APY, similar to what Cambridge Trust paid before the merger.
Is my money still FDIC insured at Cambridge Trust?
Yes. Eastern Bank is FDIC insured, and the merger did not change that. Standard coverage is $250,000 per depositor, per insured bank, per ownership category. Coverage applies to the combined institution.
Why are online savings rates so much higher than Cambridge Trust?
Online banks have no branches and lower overhead, so they can pass more interest back to depositors. Brick-and-mortar banks like Cambridge Trust and Eastern Bank price savings products to fund branch operations.
Can I close my Cambridge Trust account and switch to an online bank without penalty?
For most standard savings accounts there is no early-closure penalty. Certificates of deposit are an exception, since closing a CD before maturity usually triggers an interest forfeiture. Check your specific account terms before moving funds.
