Is The Cambridge Savings Bank Bonus Worth It?
This is a strong offer if you can meet the requirements. The full $1,200 bonus is attractive, especially because it combines both checking and money market opportunities.
The checking bonus is best for customers who can comfortably receive $2,500 or more in monthly direct deposits and keep at least $5,000 in the checking account for the required period.
The money market bonus requires a larger balance, since you need to maintain $25,000 in new money for the first 3 full calendar months. That may still be worthwhile if you already have idle cash and want to earn the $400 bonus while also earning the account’s tiered APY.
The main limitation is geographic: you must live or work in Massachusetts.
Bottom Line
Cambridge Savings Bank is offering eligible customers up to $1,200 in bonuses when they open qualifying checking and money market accounts by September 30, 2026.
You can earn:
- $500 for meeting checking setup, direct deposit, and balance requirements
- Up to $300 in monthly debit card bonuses
- $400 for opening and funding a Relationship High-Yield Money Market account
For Massachusetts residents or workers who can meet the deposit and balance requirements, this is one of the more valuable bank bonus offers currently available.
