We Ran the Early-Withdrawal Math Twice Before Signing the 4.75% CD

Five months of interest. That is the entire cost of changing our minds on the 5-year CD, and I wrote the figure at 10:05 on a Tuesday morning at the kitchen island with a spreadsheet open between me and my husband Dana and two phones showing the same Marcus login, cuz we had agreed to touch nothing until the number had been written down twice by two different people. The number came out the same both times. $396. The 4.75 percent rate stays tempting either way.

The money is my mother's condo, sold February 12 after she moved into Lavender Hills Assisted Living in January, $71,000 net after the realtor and the county, with $11,000 routed to her care escrow and $60,000 sitting in our names doin' 3.90 percent at Marcus. It is inheritance in the practical sense and mom's money in every sense that counts. We had one job: do not lose it, and do not insult it either.

The ladder is not a clever idea. It is a bet on our own patience, priced at $396, and it only works because of a paragraph most CD ads bury: the penalty schedule, printed in the 14th disclosure bullet at Marcus and the 6th at Ally, which we read before signing instead of after. We read the price list first. Most people read it after.

$71,000, then $60,000

Mom is 88, sharp, furious about the move, and thriving, in whatev order the hour demands. Her two-bedroom condo in Saginaw closed February 12 at a $92,000 sale price, $71,000 net, and per her own instruction written on a napkin in 2021, the care fund got its $11,000 top-up that same week. The remaining $60,000 came to us as the future cost of two vehicles: my 2011 Honda Civic with 164,000 miles and Dana's 2014 Rogue with a transmission that grinds in reverse. Estimated replacements: 2027 and 2029. That timeline turned out to be the whole strategy, and I did not know it yet in February.

the Marcus account at 3.90 percent

The $60,000 landed in our Marcus high-yield savings account at 3.90 percent APY, where it earned about $195 a month and could leave any minute of any day with no penalty, no questions, and no paperwork. That account is the measuring stick for everything else. Any CD hasta beat 3.90 percent, account for the penalty risk, and still justify locking money we have already promised to two cars. At 3.90, doin' nothing was already a decent plan. Doing nothin' earned $2,340 a year. The bar was real.

the ladder, three rungs

By August the rate board read: 12-month CD at 4.30 percent at Ally, 36-month at 4.50 percent at Synchrony, 60-month at 4.75 percent at Marcus, all FDIC-insured, all under the $250,000 limit with room to spare. We split the money into three $20,000 rungs, one per term, so a maturity date arrives every other year instead of never: September 2027, September 2029, September 2031. The 2027 rung matches the Civic. The 2029 rung matches the Rogue. The 2031 rung matches nothin' yet, and 2031 us will know what it is for.

the penalty in the 14th bullet

Every bank prints the early-withdrawal penalty, and none of 'em prints it on the rate page. Marcus takes 90 days of interest on the 12-month term and five months of interest on the 60-month. Ally takes 60 days' interest on terms under 24 months. Synchrony takes 180 days of interest on the 36-month, which on $20,000 at 4.50 percent is about $444. The scary one, the 60-month, runs 20,000 times 4.75 percent times five-twelfths, which is $396, cheaper than the mid-rung penalty, counterintuitive, and the reason we ran the math twice instead of eyeballing it. Dana checked my arithmetic on a legal pad. I checked his.

break-even at 28 months

The 60-month CD pays 0.85 points more than sitting in the high-yield savings account, which on $20,000 is $170 a year of extra interest. The penalty for leaving early is $396. Divide one by the other and break-even lands at 2.33 years, about 28 months, meaning any scenario where we crack the 60-month rung inside 28 months turns the whole move into a loss versus savings. The rule that fell outta the spreadsheet was simple: the 60-month rung only holds money we can swear to for at least three years. The car money never touches it. The Civic comes out of the 12-month rung in 2027, the Rogue outta the 36-month in 2029, and the 60-month rung just compounds, $950 a year, its penalty schedule sitting there unread and, we hope, unneeded.

the signatures, September 2

We opened all three CDs online September 2 in about 25 minutes: three logins, three confirmations, three PDFs saved into a folder called LADDER, cuz Dana's folders are all lowercase and mine are not. Rates locked at 4.30, 4.50, and 4.75. The savings account kept $2,100 as float for insurance and property tax surprises. Marcus showed the first 60-month interest posting on September 3, $2.61 for one day, which is the most boring number I have ever been pleased by.

the calendar reminder, June 2029

There is one calendar event named CD-36 DECISION on June 4, 2029, ninety days before the Synchrony rung matures, and its entire job is to force one question: does the Rogue wait, or does the money re-up. Shopping rates again at maturity is part of the plan, not a step we might forget. The penalty math sits in the same spreadsheet, row 19, printed once and taped inside the cabinet door. Five months of interest is what impatience costs on rung three. We do not plan to be impatient. That is the whole decision.
