A 0.25% change in the U.S. prime rate — currently 6.75%, effective December 11, 2025 — moves the interest cost on a $5,000 credit card balance by about $12.50 per year, a $50,000 HELOC by about $125 per year, and a $150,000 SBA 7(a) business loan by about $375 per year. The prime rate is the benchmark interest rate large commercial banks publish for their most creditworthy customers, and it flows directly into the APR on most credit cards, home equity lines of credit, SBA 7(a) loans, and variable-rate personal and business loans. Every U.S. bank sets its own prime, but since 1994 they have all followed the same formula: federal funds rate upper bound + 3.00%.
- The current U.S. prime rate is 6.75%, effective December 11, 2025 — unchanged through the Fed’s January 28, 2026 FOMC meeting.
- Formula: prime rate = federal funds rate (upper bound) + 3.00%. The 3.00% spread has held steady since 1994.
- Prime directly sets rates on most credit cards (typically prime + 10% to + 25%), HELOCs, SBA 7(a) loans, and variable-rate personal loans — but not 30-year fixed mortgages or auto loans.
- A 0.25% prime rate change moves the interest cost on a $50,000 HELOC by about $125 per year, and on a $150,000 SBA 7(a) loan by about $375 per year.
- Historical high: 21.50% (December 19, 1980). Historical low: 3.25% (December 16, 2008 and March 16, 2020).
What the Prime Rate Is and Why It Sets Your Payment
The prime rate is the benchmark interest rate that large U.S. commercial banks publish as the rate they would charge their best corporate customers — the businesses with the strongest credit and lowest default risk. In practice, almost no one borrows at the pure prime rate. Instead, lenders quote consumer and business loans as “prime plus a margin,” where the margin reflects the added risk of that specific borrower and product.
When people talk about “the prime rate,” they almost always mean the Wall Street Journal prime rate. This single published number is calculated from a daily survey of the top 25 U.S. commercial banks by assets and is reported on the Federal Reserve’s H.15 Selected Interest Rates release. It only changes when a majority of those banks move in unison — which, in modern practice, means it only changes when the Federal Reserve moves the federal funds rate. You can see the current figure and change history on our current U.S. prime rate page.
How the Prime Rate Is Set
Technically, the prime rate is not set by the government, the Federal Reserve, or any single bank. Each commercial bank declares its own prime independently. In practice, however, virtually every major U.S. bank has followed the same formula since the mid-1990s: prime rate = federal funds rate (upper bound of the Fed’s target range) + 3.00%.
Here is how that math works today. At its December 2025 meeting, the Federal Reserve cut the federal funds target range to 3.50%–3.75%. The upper bound of that range is 3.75%. Add the 3.00% prime spread and you get 6.75% — the current U.S. prime rate. When the Fed hiked aggressively from March 2022 through July 2023, the upper bound reached 5.50% and prime sat at 8.50%. When the Fed cut rates emergency-style in March 2020, the upper bound fell to 0.25% and prime hit its recent floor of 3.25%.
The 3.00% spread itself is a convention, not a law. Before the early 1990s the spread was closer to 1.50%, and individual banks sometimes led or lagged each other by days or weeks. After the Federal Deposit Insurance Corporation Improvement Act of 1991 and the Fed’s shift to a more transparent rate-setting regime, banks converged on the uniform 3.00% premium and the 24-to-48-hour reaction window we see today. Once the FOMC announces a change, most of the top 25 banks update their posted prime rate by the close of the next business day.
The 3.00% prime-to-Fed-funds spread is not universal. The European Central Bank, the Bank of England, and the Bank of Canada each publish their own benchmark rates using different spreads and methodologies. If you hold a U.S. credit card or HELOC, only the U.S. prime rate matters — but if you are borrowing in another currency or dealing with a foreign subsidiary, do not assume the same 3.00% rule applies. Check the specific base rate your loan agreement references before you estimate future payments.
What the Prime Rate Affects (and What It Doesn’t)
Not every loan moves with the prime rate. Understanding which of your debts are tied to prime — and which are not — is the difference between bracing for every FOMC announcement and ignoring it. Here is the practical breakdown for U.S. consumers and small business owners.
Loans and credit tied directly to the prime rate
- Credit cards. Nearly all variable-rate credit cards price at prime + a margin of roughly 10% to 25%. A card quoted at “Prime + 15.74%” has a current APR of 22.49% (6.75% + 15.74%). See how the prime rate affects credit card interest rates for the mechanics.
- Home equity lines of credit (HELOCs). Most HELOCs are quoted as prime + 0.00% to + 2.00% during the draw period, with a lifetime ceiling. Our guide to how prime affects mortgages and HELOCs breaks down the full pricing.
- SBA 7(a) small business loans. The SBA caps lender spreads between prime + 3.00% (loans over $350,000) and prime + 6.50% (loans of $50,000 or less). The SBA added three alternative base rates — 5-year Treasury, 10-year Treasury, and SOFR — effective March 1, 2026, but WSJ Prime remains the dominant base rate used by 7(a) lenders.
- Variable-rate personal loans and personal lines of credit. Less common than fixed-rate personal loans, but when offered, the variable APR usually floats off prime. See our coverage of prime rate and personal loans.
- Business lines of credit and working capital loans. Most bank and fintech business lines quote as prime + a margin. A move in prime shows up on the next statement cycle.
Loans not tied to the prime rate
- 30-year fixed mortgages. Mortgage rates track the 10-year U.S. Treasury yield plus a spread, not prime. A Fed cut can move prime without moving your mortgage rate at all.
- Auto loans. Auto loan pricing is driven by the captive-finance market, credit tier, and used-car residual values, not prime.
- Fixed-rate personal loans. Once you lock in a fixed-rate personal loan with a lender like SoFi, Upstart, or LightStream, your APR does not change for the life of the loan regardless of what prime does.
- Student loans. Federal student loan rates are set annually by Congress based on the 10-year Treasury, not prime. Most private fixed-rate student loans are also insulated from prime once locked.
- CDs and high-yield savings accounts. Deposit rates follow the federal funds rate and short-end Treasury yields, not prime directly. They usually move the same direction as prime, but the timing and magnitude differ.
How a Prime Rate Change Hits Your Wallet
The Fed typically moves the federal funds rate in 0.25% increments, which translates to 0.25% moves in prime. That sounds small on paper. In dollars, it is not. Here is what a single 0.25% move does across the debts most Americans carry.
$5,000 credit card balance at 22.49% APR (prime + 15.74%). A 0.25% prime hike raises the APR to 22.74% and adds roughly $12.50 per year in interest if you carry that balance continuously. A 0.25% cut saves the same amount. The cumulative 1.75% in cuts the Fed delivered between September 2024 and December 2025 dropped the interest cost on this same balance by about $87.50 per year.
$50,000 HELOC at prime + 1.50% (currently 8.25%). A 0.25% move changes your HELOC APR to 8.50% or 8.00%. During the interest-only draw period, that swings your monthly interest payment by about $10.42. Annualized, a 0.25% prime rate change on a $50,000 HELOC is worth roughly $125 per year. Over a 10-year draw period, a single full percentage point of Fed tightening compounds to $5,000 in extra interest.
$150,000 SBA 7(a) loan at prime + 2.75% (currently 9.50%). For SBA 7(a) loans of $150,001 to $250,000, the maximum spread is prime + 6.00%, but competitive lenders offer closer to prime + 2.75% for strong borrowers. A 0.25% prime rate change moves the annual interest cost on this balance by about $375, and a full 1.00% move — a typical Fed cycle — changes the monthly payment by roughly $125. For long-term 10-year business loans, the lifetime interest difference from one full Fed tightening cycle can exceed $7,500 on a $150,000 balance.
When a prime rate change is announced, most credit card issuers, HELOC servicers, and SBA lenders apply the new rate on the next statement cycle — typically 30 to 60 days later. That gap creates a small window of arbitrage for balance transfers. If the Fed signals a likely hike at the upcoming FOMC meeting, lock a 0% intro APR balance transfer offer the week before. If the Fed signals a likely cut, wait until the cycle after the cut to refinance a variable-rate debt into a lower-rate product. Either way, track the FOMC meeting schedule so you are never caught off guard.
Prime Rate History and Where It’s Headed
The U.S. prime rate has a long and volatile history. Its all-time high was 21.50%, reached on December 19, 1980, during Federal Reserve Chair Paul Volcker’s campaign to break double-digit inflation. At that rate, a $100,000 business loan cost $21,500 per year in interest alone. On the other end, the prime rate hit its modern low of 3.25% on two separate occasions: December 16, 2008, during the global financial crisis, and again on March 16, 2020, in the first weeks of the COVID-19 pandemic. Each floor lasted several years before the Fed began raising rates.
The most recent full cycle saw prime climb from 3.25% in March 2022 to 8.50% by July 2023 — a 5.25-point increase over 16 months, the fastest tightening cycle in four decades. Starting in September 2024 the Fed began cutting, and by December 2025 prime had settled at 6.75%. At the FOMC’s January 28, 2026 meeting, the committee held rates steady, and market expectations for additional cuts in 2026 remain data-dependent.

Frequently Asked Questions
What is the prime rate today?
The U.S. prime rate is 6.75%, effective December 11, 2025. The Federal Reserve held rates steady at its January 28, 2026 FOMC meeting, so the prime rate has remained at 6.75% since December. The rate is published daily on the Federal Reserve’s H.15 Selected Interest Rates release and is surveyed from the top 25 U.S. commercial banks.
Who sets the prime rate?
No single entity sets the U.S. prime rate. Each commercial bank declares its own prime independently. In practice, virtually every major bank has followed the same formula since 1994: federal funds rate upper bound plus 3.00%. The Wall Street Journal calculates the published prime rate from a daily survey of the top 25 U.S. commercial banks, and it changes when a majority of those banks move in unison — almost always within 24 hours of a Federal Reserve rate decision.
How much will my payment change when the prime rate moves 0.25%?
A 0.25% prime rate change moves the interest cost on a $5,000 credit card balance by about $12.50 per year, a $50,000 HELOC by about $125 per year ($10.42 per month during the interest-only draw period), and a $150,000 SBA 7(a) loan by about $375 per year. For a 30-year mortgage, a 0.25% prime move has zero direct impact, because fixed mortgages are tied to the 10-year Treasury yield, not prime.
Should I refinance to a fixed rate when the prime rate rises?
It depends on your balance, your remaining term, and where rates are expected to go. A rule of thumb: if you carry a variable-rate balance above $25,000 and the Fed is in an active tightening cycle, the interest savings from locking a fixed rate often outweigh origination fees within 12 to 18 months. For smaller balances or late in a hiking cycle, staying variable and waiting for cuts is usually the better math. Run the numbers on your specific balance before switching.
Does the prime rate affect my fixed-rate mortgage?
No. A 30-year fixed-rate mortgage is priced off the 10-year U.S. Treasury yield, not the prime rate. Once your fixed mortgage closes, your rate is locked for the full term. The prime rate does affect home equity lines of credit (HELOCs) and some adjustable-rate mortgages, but traditional fixed mortgages are insulated from prime rate changes entirely.
How often does the prime rate change?
The prime rate changes only when the Federal Reserve changes the federal funds rate, which the FOMC reviews at eight scheduled meetings per year. In quiet years, prime may not change at all. In active tightening or easing cycles, it can change at multiple consecutive meetings. From March 2022 through July 2023 prime rose 11 times in 16 months. Since September 2024 it has fallen three times.
Why is it called the “prime” rate?
The term dates to the 1930s, when banks began publishing a single rate reserved for their “prime” customers — the largest and most creditworthy corporations that posed minimal default risk. The word “prime” in this context means “highest quality,” the same way a butcher refers to prime-grade beef. Everyone else borrows at a premium above prime that reflects the added credit risk of their specific profile.
Next Steps: Making the Prime Rate Work for You
The prime rate is one of the few macroeconomic numbers that translates directly into your household budget or your business’s interest expense. The practical takeaway is not to obsess over every basis point, but to know which of your debts are tied to it and roughly how much a typical 0.25% move changes your annual interest bill. From there, the decisions get easier: if you are carrying a variable-rate balance and expect more Fed cuts, staying put may save money; if you expect hikes, refinancing into a fixed-rate product can lock in today’s cost.
Want to model a specific scenario? Use the prime rate impact calculator to see how a 0.25%, 0.50%, or 1.00% move would change your monthly payment on any variable-rate balance. If you are comparing a fixed loan against a variable one, the prime vs. fixed rate calculator runs the side-by-side math. And to time any refinance or new borrowing around the next rate move, bookmark the FOMC meeting schedule.
