I got Marcus Bank bonus for adding required amount of funds to my Marcus Bank Online Savings account
I got my Marcus Bank bonus credited to my online savings account one day after the 90-day maintenance period ended in May.
Here's the timeline:
Fall 2025 - Open Marcus Bank Online Savings account
January 29, 2026 - Receive an email saying if I add a certain amount of NEW funds from outside Marcus Bank to my Marcus Bank Online Savings account I'll get a bonus. The tiers are $100 bonus if I add $10,000; $750 if I add $50,000 and $1,500 if I add $100,000. I have to go to a web page to enroll in the offer by March 11. I have 10 calendar days from enrollment date to transfer in the necessary funds and then I have to maintain those funds in the Online Savings accounts for 90 days. The bonus will then be credited to the Online Savings account within 14 days after the 90 days ends. To ensure I don't transfer funds out from any Marcus Bank accounts and then transfer them back in to get the bonus, I have to maintain for 90 days after the 10-day period my Online Savings balance as of 6 p.m. Jan. 26 plus the added funds AND my total Marcus Bank balance including my CD accounts plus the added funds.
February 9, 2026 - Visit the website page for promotion (there's a URL provided in that email) and enroll in the offer. I receive a confirmation email that I'm enrolled in the offer. I'm told I have until Feb. 19 to transfer in the funds. A cash bonus tracker immediately shows up in my Marcus Bank account on the bank website and the Marcus app. It shows that I have until Feb. 19 to transfer the funds, how much in funds I've transferred in and the bonus I'm eligible for, the end of the maintenance period on May 20 and that I'm set to get the bonus by June 3. The bonus tracker is updated once a day so it can be a day or two before a transfer shows up in the tracker. After the transfers are completed - within a couple of days the tracker updates and accurately shows how much I've transferred in, the Online Savings account balance I must maintain and my total Marcus Bank balance I must maintain and the bonus I'm eligible for. I also get a warning that if any of my no-penalty CDs mature or are closed without the CD being renewed I must transfer the funds to the Marcus Bank Online Savings. If the funds go to an external account, that could bring the total balance down to the point I go down a bonus tier or not get a bonus at all.
Feb. 10 to Feb. 13, 2026 - I add an external account to Marcus Bank and I have Marcus Bank pull all the funds from the other bank in four transfers spread out over four days. The advantage of doing this is I'm credited the interest starting from the moment I initiated the ACH pull. There's not the typical one to three business day hold before interest may accrue. However, funds may not be available for withdrawal for about a week to 10 days. So for an ACH pull transfer scheduled on Feb. 10, the funds would not be available until Feb. 18. I find that if I time the transfer for after 3 p.m., the money doesn't leave the external account until the next business day meaning I'm being credited the interest for that day with Marcus Bank and the other bank. If I scheduled the transfer prior to 3 p.m. or 2 p.m. then the money leaves the external account by the end of the business day.
Feb. 20, 2026 - The 90-day maintenance period begins. I do not touch any funds during the maintenance period. Interest is credited on the last day of each month.
May 20, 2026 - 90-day maintenance period ends.
May 21, 2026 - The bonus is credited to my Online Savings account well before the June 3 deadline and the bonus tracker disappears.
