Everything You Need to Know About the Prime Rate
The prime rate is the interest rate that commercial banks charge their most creditworthy customers and serves as the benchmark for most variable-rate lending in the United States. Currently at 6.75% after five consecutive Federal Reserve rate cuts since September 2024, the prime rate directly determines what you pay on credit cards (prime + 12%–23% margin), SBA loans (prime + 2.25%–4.75%), HELOCs (prime + 1%–2%), and adjustable-rate mortgages.
Key Facts About the Prime Rate
- The current U.S. prime rate is 6.75%, effective December 11, 2025, after the Fed cut the federal funds rate to 3.50%–3.75%.
- Prime rate = federal funds rate upper bound + 3.00%. This formula has held since 1994. When the Fed moves, prime follows within one business day.
- The prime rate has ranged from a record high of 21.50% (December 1980) to a record low of 3.25% (December 2008 and March 2020).
- Over $4.8 trillion in U.S. consumer debt is tied to the prime rate, including credit cards, HELOCs, SBA loans, and adjustable-rate mortgages, per Federal Reserve G.19 data.
- The next FOMC meeting is May 6–7, 2026. Markets currently expect the Fed to hold rates steady, keeping prime at 6.75% through mid-2026.

What Is the Prime Rate?
The prime rate is a benchmark interest rate published by the Wall Street Journal based on a survey of the 30 largest U.S. banks. When 23 of the 30 banks (three-quarters) change their base lending rate, the WSJ updates the published prime rate. In practice, all 30 banks move simultaneously because the prime rate is mechanically linked to the federal funds rate set by the Federal Reserve.
The formula is simple: prime rate = federal funds rate (upper bound) + 3.00%. With the current fed funds target at 3.50%–3.75%, the prime rate is 3.75% + 3.00% = 6.75%. This 3-point spread has been consistent since 1994, making the prime rate entirely predictable once you know the Fed’s target rate.
Banks do not actually lend to most customers at the prime rate. It serves as a floor or index — your actual rate is prime plus a margin based on your creditworthiness. A consumer with excellent credit might get a HELOC at prime + 0.5% (7.25%), while a credit card for a fair-credit borrower might be prime + 18% (24.75%). The prime rate itself is what the bank charges its very best corporate customers for short-term operating loans.
How Is the Prime Rate Set?
The prime rate is not set by law or regulation. It is a market convention that follows the Federal Reserve’s monetary policy decisions. Here is the chain of events when the prime rate changes:
Step 1: The FOMC meets. The Federal Open Market Committee (FOMC) meets 8 times per year to set the federal funds rate target range. This is the overnight rate at which banks lend reserves to each other.
Step 2: Banks adjust prime. Within one business day of an FOMC rate change, the 30 largest U.S. banks adjust their prime lending rate by the same amount. If the Fed cuts 25 basis points, prime drops 25 basis points. The relationship is mechanical, not discretionary.
Step 3: Consumer rates adjust. All variable-rate products tied to prime — credit cards, HELOCs, SBA loans, adjustable-rate mortgages — adjust on their next statement cycle. Fixed-rate products (most personal loans, conventional mortgages) are not directly affected but may shift over time as market conditions change.
The CFPB notes that most consumers experience prime rate changes through their credit card statements first, since credit card issuers adjust APRs within one billing cycle of a Fed rate change.
Prime Rate History: 1980–Present
The prime rate has experienced dramatic swings over the past four decades, reflecting major shifts in monetary policy and economic conditions. According to Federal Reserve (FRED) data:
1980–1982: The Volcker era. Fed Chair Paul Volcker raised rates to combat double-digit inflation, pushing prime to an all-time high of 21.50% in December 1980. A $100,000 home equity loan at that rate cost $1,792/month — compared to $467/month at today’s 6.75%.
1990–2000: The Great Moderation. Prime gradually declined from 10% to 9.5% as inflation stabilized. The dot-com boom pushed rates back to 9.5% by 2000.
2001–2003: Post-9/11 cuts. The Fed slashed rates aggressively, dropping prime from 9.5% to 4.0% — the lowest since the 1950s at that time.
2007–2009: Financial crisis. Prime fell from 8.25% to 3.25% as the Fed cut rates to near zero. The 3.25% prime rate lasted from December 2008 through December 2015 — seven years of the lowest prime rate in modern history.
2022–2023: Inflation fight. The Fed raised rates 11 times in 16 months, pushing prime from 3.25% to 8.50% — the fastest tightening cycle since the early 1980s.
2024–present: Easing cycle. Five rate cuts since September 2024 have brought prime from 8.50% to 6.75%. Markets expect further gradual cuts through 2026–2027. For detailed historical data, see our Prime Rate History article and the Prime Rate Forecast Calculator.
What the Prime Rate Affects
The prime rate flows through to virtually every variable-rate financial product in the United States. Here is how a 0.25% change in prime affects each product type:
| Product | Typical Rate Formula | Current Rate | Impact of +0.25% | Annual Cost on $50K |
|---|---|---|---|---|
| Credit cards | Prime + 12%–23% | 18.75%–29.75% | +$12.50/yr per $5K | +$125 |
| HELOCs | Prime + 0.5%–2% | 7.25%–8.75% | +$12.50/yr per $50K | +$125 |
| SBA 7(a) loans | Prime + 2.25%–4.75% | 9.0%–11.5% | +$10.42/mo per $50K | +$125 |
| Adjustable-rate mortgages | Prime + 0%–1% | 6.75%–7.75% | +$8.33/mo per $200K | +$500 (on $200K) |
| Auto loans (variable) | Prime + 1%–5% | 7.75%–11.75% | +$5.21/mo per $30K | +$75 (on $30K) |

Prime Rate Forecast
The prime rate forecast depends entirely on Federal Reserve policy. Based on CME FedWatch Tool data and FOMC dot-plot projections as of March 2026:
2026 FOMC meeting schedule and market expectations:
- March 18–19 (completed): Held steady at 3.50%–3.75%. Prime stays at 6.75%.
- May 6–7: Markets expect hold. Prime stays at 6.75%.
- June 17–18: Possible 25bp cut if inflation data cooperates. Prime could drop to 6.50%.
- July 29–30: Data dependent. Hold or cut.
- September 16–17: Markets price ~60% probability of a cut by this meeting.
- October 28–29, December 16–17: Year-end positioning, further cuts possible.
Consensus forecast: Most economists expect 1–2 additional rate cuts in 2026, potentially bringing prime to 6.25%–6.50% by year-end. However, persistent inflation above the Fed’s 2% target could delay cuts. Explore scenarios with our Prime Rate Forecast Calculator and read our full Prime Rate Forecast analysis.
Prime Rate vs Other Rates
The prime rate is one of several benchmark rates in the U.S. financial system. Understanding the differences helps you evaluate loan offers and anticipate rate changes.
Prime rate vs federal funds rate. The federal funds rate is the overnight rate banks charge each other. Prime = fed funds + 3%. The fed funds rate is set by the FOMC; prime follows mechanically. Read our detailed comparison: Prime Rate vs Federal Funds Rate vs SOFR.
Prime rate vs SOFR. The Secured Overnight Financing Rate (SOFR) replaced LIBOR as the benchmark for institutional lending and adjustable-rate mortgages. SOFR is currently ~3.50%, roughly tracking the fed funds rate. Prime is used for consumer and small business lending; SOFR is used for wholesale/institutional products.
Prime rate vs Treasury yields. Treasury yields (10-year, 30-year) are set by market supply and demand, not the Fed. Fixed-rate mortgages track the 10-year Treasury, not the prime rate. When the Fed cuts and prime drops, fixed mortgage rates may not follow if the bond market expects future inflation. This is why HELOCs (tied to prime) may offer lower rates than fixed mortgages during easing cycles.
Prime rate vs APR. APR is the total annual cost of borrowing including fees. Prime is a benchmark rate. Your APR = prime + margin + any fees annualized. A credit card at prime + 15% with a $95 annual fee has a higher effective APR than the rate alone suggests. The CFPB’s credit card tools explain how to compare APR across issuers.
Frequently Asked Questions
What is the current prime rate?
The current U.S. prime rate is 6.75%, effective December 11, 2025. It is published by the Wall Street Journal and based on the Federal Reserve’s federal funds rate target of 3.50%–3.75% plus a 3.00% spread. Prime changes only when the Fed adjusts the federal funds rate.
Who sets the prime rate?
The prime rate is set by individual banks, but in practice all major banks move in lockstep with the Federal Reserve. The Wall Street Journal publishes the consensus rate based on a survey of the 30 largest U.S. banks. When the Fed changes its target rate, banks adjust prime by the same amount within one business day.
How does the prime rate affect my credit card?
Most credit card APRs are calculated as prime + a fixed margin (typically 12%–23%). At 6.75% prime, a card with prime + 15% margin charges 21.75% APR. When prime drops 0.25%, your APR drops to 21.50%. On a $5,000 balance, this saves about $12.50/year. The change appears on your next billing statement.
How does the prime rate affect mortgage rates?
HELOCs and adjustable-rate mortgages are directly tied to prime (prime + 0.5%–2% for HELOCs). Fixed-rate conventional mortgages are NOT tied to prime — they track the 10-year Treasury yield instead. When the Fed cuts and prime drops, your HELOC rate falls but your fixed mortgage rate may not change.
Will the prime rate go down in 2026?
Market expectations as of March 2026 suggest 1–2 additional rate cuts are possible in the second half of 2026, potentially bringing prime to 6.25%–6.50% by year-end. However, the Fed has emphasized that future cuts depend on inflation data reaching the 2% target sustainably.
What is the difference between the prime rate and the federal funds rate?
The federal funds rate is the overnight rate banks charge each other for reserves, set by the FOMC. The prime rate is what banks charge their best customers, always 3.00% above the federal funds rate upper bound. The fed funds rate is currently 3.50%–3.75%, making prime 6.75%. They always move together.
