This is my monthly roundup of the best interest rates on cash, roughly sorted from shortest to longest maturities. Check out my Ultimate Rate-Chaser Calculator to get an idea of how much additional interest you’d earn if you are moving money between accounts. Rates listed are available to everyone nationwide. Rates checked as of 9/4/18.

High-yield savings accounts
While the huge megabanks like to get away with 0.01% APY, getting higher rates is as easy as transferring some money electronically from your checking account to an online savings account. Keep in mind that the interest rates on savings accounts can drop at any time, so consider prioritizing banks with a history of competitive rates.

• CIT Bank Money Market offers 1.85% APY with no minimum balance ($100 to open), no max balance cap. Redneck Bank offers 2.00% APY on a maximum balance of $50k. Several other established high-yield savings accounts are in this close range.
• In terms of newcomers, Customers Bank offers 2.25% APY guaranteed until 6/30/19, but with a minimum balance of $25k+. Northfield Bank has a Platinum Savings Online (not their regular Platinum Savings) at 2.25% APY up to $100k, but there is an $8 monthly fee if under $2,500.
• My “hub” bank account is the Ally Bank Savings + Checking combo due to their history of competitive rates, 1-day external bank transfers, and overall ease of use. The free overdraft transfers from savings allows to me to keep my checking balance at a minimum. Ally Savings is currently at 1.85% APY. From here, I open “spoke” accounts and CDs to lock in higher rates.

Money market mutual funds + Ultra-short bond ETFs
If you like to keep cash in a brokerage account, you should know that money market and short-term Treasury rates have been rising. The following money market and ultra-short bond funds are not FDIC-insured, but may be a good option if you have idle cash and cheap/free commissions.

• Vanguard Prime Money Market Fund currently pays an 2.08% SEC yield. The default sweep option is the Vanguard Federal Money Market Fund, which has an SEC yield of 1.93%. You can manually move the money over to Prime if you meet the $3,000 minimum investment.
• Vanguard Ultra-Short-Term Bond Fund currently pays 2.42% SEC Yield ($3,000 min) and 2.52% SEC Yield ($50,000 min). The average duration is ~1 year.
• The PIMCO Enhanced Short Maturity Active Bond ETF (MINT) has a 2.42% SEC yield and the iShares Short Maturity Bond ETF (NEAR) has a 2.54% SEC yield while holding a portfolio of investment-grade bonds with an average duration of ~6 months.

Short-term guaranteed rates (1 year and under)
I am often asked what to do with a big wad of cash that you’re waiting to deploy shortly (just sold your house, just sold your business, legal settlement, inheritance). My usual advice is to keep things simple. If not a savings account, then put it in a flexible short-term CD under the FDIC limits until you have a plan.

• USALLIANCE Financial Credit Union has a 1-year CD at 2.75% APY ($500 minimum new money) with an early withdrawal penalty of 6 months interest. You must join the credit union first, but anyone can join via American Consumer Council (ACC). CIT Bank 1-year CD is at 2.50% APY ($1,000 minimum) with an early withdrawal penalty of 3 months interest.
• For more flexibility, the Ally Bank 11-month No Penalty CD is at 2.00% APY ($25k minimum) and the CIT Bank 11-Month No-Penalty CD is at 1.85% APY with a lower $1,000 minimum. The lack of early withdrawal penalty means that your interest rate can never go down for 11 months, but you keep full liquidity. You can open multiple CDs in smaller $1,000 increments to get even more flexibility.

US Savings Bonds
Series I Savings Bonds offer rates that are linked to inflation and backed by the US government. You must hold them for at least a year. There are annual purchase limits. If you redeem them within 5 years there is a penalty of the last 3 months of interest.

• “I Bonds” bought between May 2018 and October 2018 will earn a 2.52% rate for the first six months. The rate of the subsequent 6-month period will be based on inflation again. More info here.
• In mid-October 2018, the CPI will be announced and you will have a short period where you will have a very close estimate of the rate for the next 12 months. I will have another post up at that time.

Prepaid Cards with Attached Savings Accounts
A small subset of prepaid debit cards have an “attached” FDIC-insured savings account with exceptionally high interest rates. The negatives are that balances are capped, and there are many fees that you must be careful to avoid (lest they eat up your interest). Some folks don’t mind the extra work and attention required, while others do. There is a long list of previous offers that have already disappeared with little notice.

• The only notable card left in this category is Mango Money at 6% APY on up to $5,000, but there are many hoops to jump through. There is a $3 monthly fee and you need to maintain a minimum $800 net direct deposit each month. This means you can’t direct deposit $800 and also take out $800 via online transfer. Checks and ATM withdrawals have additional fees. The only thing left is to spend the money via the Visa debit feature (and miss out on flat 2% cash back on all purchases).

Rewards checking accounts
These unique checking accounts pay above-average interest rates, but with unique risks. You have to jump through certain hoops, and if you make a mistake you won’t earn any interest for that month. Some folks don’t mind the extra work and attention required, while others do. Rates can also drop to near-zero quickly, leaving a “bait-and-switch” feeling. That’s just how it goes with these types of accounts.

• Consumers Credit Union recently announced changes starting 10/1/18, including lower balance limits ($10k down from $20k) and more restrictive requirements, but also higher interest rates in some tiers. Free Rewards Checking now offers 3.09% to 5.09% APY on up to a $10k balance depending on your qualifying activity. The highest tier requires their credit card in addition to their debit card (other credit cards offer $500+ in sign-up bonuses). Keep your 12 debit purchases just above the $100 requirement, as for every $500 in monthly purchases you may be losing out on 2% cash back elsewhere (or $10 a month after-tax). Thanks to reader Jonathan for the heads up. Find a local rewards checking account at DepositAccounts.

Certificates of deposit (greater than 1 year)
You might have larger balances, either because you are using CDs instead of bonds or you simply want a large cash reserves. By finding a bank CD with a reasonable early withdrawal penalty, you can enjoy higher rates but maintain access in a true emergency. Alternatively, consider building a CD ladder of different maturity lengths such that you have access to part of the ladder each year, but your blended interest rate is higher than a savings account.

• Synchrony Bank has a special 13-month CD at 2.65% APY ($2,000 min). Note that the early withdrawal penalty is relatively big at 6 months of interest. NASA Federal Credit Union has a special 15-month Share Certificate at 3.25% APY ($5,000 min, EWP 6 months). Anyone can join this credit union by joining the National Space Society (free). However, NASA FCU will perform a hard credit check as part of new member application.
• Ally Bank has a 5-year CD at 3.00% APY ($25k minimum) with a relatively short 150-day early withdrawal penalty. For example, if you closed this CD after 2 years you’d still get a 2.39% effective APY even after accounting for the penalty. (2.61% at 3 years.)
• United States Senate Federal Credit Union has a 5-year Share Certificate at 3.53% APY ($60k min), 3.47% APY ($20k min), or 3.41% APY ($1k min). Note that the early withdrawal penalty is a full year of interest. Anyone can join this credit union via American Consumer Council.
• You can buy certificates of deposit via the bond desks of Vanguard and Fidelity. These “brokered CDs” offer FDIC insurance, but they don’t come with predictable fixed early withdrawal penalties. As of this writing, Vanguard is showing a 3-year non-callable CD at 3.00% APY and a 5-year non-callable CD at 3.35% APY. Watch out for higher rates from callable CDs listed by Fidelity.

Longer-term Instruments
I’d use these with caution due to increased interest rate risk, but I still track them to see the rest of the current yield curve.

• Willing to lock up your money for 10+ years? You can buy long-term certificates of deposit via the bond desks of Vanguard and Fidelity. These “brokered CDs” offer FDIC insurance, but they don’t come with predictable fixed early withdrawal penalties. As of this writing, Vanguard is showing a 10-year non-callable CD at 3.45% APY. Watch out for higher rates from callable CDs from Fidelity. Matching the overall yield curve, current CD rates do not rise much higher as you extend beyond a 5-year maturity.
• How about two decades? Series EE Savings Bonds are not indexed to inflation, but they have a guarantee that the value will double in value in 20 years, which equals a guaranteed return of 3.5% a year. However, if you don’t hold for that long, you’ll be stuck with the normal rate which is quite low (currently a sad 0.10% rate). I view this as a huge early withdrawal penalty. You could also view it as long-term bond and thus a hedge against deflation, but only if you can hold on for 20 years.

High-yield savings accounts
While the huge brick-and-mortar banks like to get away with 0.01% APY, there are a number of online savings accounts offering much higher rates. Keep in mind that with savings accounts, the interest rates can change at any time.

• CIT Bank Money Market offers 1.85% APY with no minimum balance ($100 to open) and no max balance cap. Several others have similar rates (see interactive tool below). Customers Bank offers 2.25% APY guaranteed until 6/30/19, but with a minimum balance of $25k+. On the flip side, Redneck Bank offers 2.00% APY but on a maximum balance of $50k.
• My “hub” bank account is the Ally Bank Savings + Checking combo due to their history of competitive savings/CD rates, 1-day external bank transfers, and overall user experience. The free overdraft transfers from savings allows to me to keep my checking balance at a minimum. Ally Savings is currently at 1.80% APY. From here, I open “spoke” accounts and CDs to lock in higher rates.

Money market mutual funds + Ultra-short bond ETFs
If you like to keep cash in a brokerage account, you should know that money market and short-term Treasury rates have been rising. The following money market and ultra-short bond funds are not FDIC-insured, but may be a good option if you have idle cash and cheap/free commissions.

• Vanguard Prime Money Market Fund currently pays an 2.06% SEC yield. The default sweep option is the Vanguard Federal Money Market Fund, which has an SEC yield of 1.87%. You can manually move the money over to Prime if you meet the $3,000 minimum investment.
• Vanguard Ultra-Short-Term Bond Fund currently pays 2.44% SEC Yield ($3,000 min) and 2.54% SEC Yield ($50,000 min). The average duration is ~1 year.
• The PIMCO Enhanced Short Maturity Active Bond ETF (MINT) has a 2.45% SEC yield and the iShares Short Maturity Bond ETF (NEAR) has a 2.47% SEC yield while holding a portfolio of investment-grade bonds with an average duration of ~6 months.

My usual advice is to keep things simple. If not a savings account, then put it in a flexible short-term CD under the FDIC limits until you have a plan.

• United Texas Bank has a 1-year CD at 2.80% APY. CIT Bank 1-year CD is at 2.50% APY ($1,000 minimum). Early withdrawal penalty is 3-months of interest. For more flexibility, the Ally Bank 11-month No Penalty CD is at 2.00% APY ($25k minimum) and the CIT Bank 11-Month No-Penalty CD is at 1.85% APY with a lower $1,000 minimum. The lack of early withdrawal penalty means that your interest rate can never go down for 11 months, but you keep full liquidity. You can open multiple CDs in smaller $1,000 increments to get even more flexibility.
• Several other banks now have 12-month CDs at 2% APY and above. Watch the early withdrawal penalties. For example, Synchrony Bank has a 2.45% APY 12-month CD, but the early withdrawal penalty is 90 days of interest. Meanwhile, Ally Bank has a 12-month CD at 2.40% APY with $25k+ deposit (2.25% APY for $5k+) and early withdrawal penalty of 60 days interest.

• Consumers Credit Union offers up to 4.59% APY on up to a $20k balance, although getting 3.09% APY on a $10k balance has a much shorter list of requirements. The 4.59% APY requires you to apply for a credit card through them (other credit cards offer $500+ in sign-up bonuses). Keep your 12 debit purchases small as well, as for every $500 in monthly purchases you may be losing out on 2% cashback (or $10 a month after-tax).

• Connexus Credit Union is offering a 1-year Share Certificate at 2.50% APY (90-day early withdrawal penalty), a 3-year Share Certificate (180-day early withdrawal penalty) at 2.75% APY, and a 5-year Share Certificate (365-day early withdrawal penalty) at 3.25% APY. All have a $5,000 minimum deposit. Anyone can join this credit union via partner organization Connexus Association for a one-time $5 fee.
• You can buy certificates of deposit via the bond desks of Vanguard and Fidelity. These “brokered CDs” offer FDIC insurance, but they don’t come with predictable fixed early withdrawal penalties. As of this writing, Vanguard is showing a 3-year non-callable CD at 3.00% APY and a 5-year non-callable CD at 3.30% APY from a few banks including American Express and Citibank. Watch out for higher rates from callable CDs listed by Fidelity.

Longer-term Instruments
I’d use these with caution due to increased interest rate risk, but I still track them to see the rest of the current yield curve.

• Willing to lock up your money for 10+ years? You can buy long-term certificates of deposit via the bond desks of Vanguard and Fidelity. These “brokered CDs” offer FDIC insurance, but they don’t come with predictable fixed early withdrawal penalties. As of this writing, Vanguard is showing a 10-year non-callable CD at 3.45% APY.
