A competitive U.S. House campaign typically costs about $2 million, and a competitive Senate campaign can easily run into the tens of millions. That’s the short answer to how much it costs to run for Congress. Across the 2023–2024 cycle, congressional candidates collectively raised $3.8 billion and spent $3.7 billion, and that figure doesn’t count the billions more that outside groups poured into the same races.1Federal Election Commission. Statistical Summary of 24-Month Campaign Activity of the 2023-2024 Election Cycle
The real answer depends on which chamber you’re aiming for, how competitive your race is, and where in the country you’re running.
What a House Race Costs
In the 2024 cycle, the median sitting House member seeking reelection raised roughly $2.1 million. That works out to about $2,900 a day over the two-year cycle. Freshman incumbents raised more, with a median around $2.4 million.
The spread around those medians is enormous. A candidate in a safe district where the other party has no realistic shot can win spending well under $500,000. Candidates in genuine toss-up seats routinely spend north of $2.5 million each, and in the most expensive House races the number climbs higher still. Competitiveness is the single biggest driver of cost, ahead of geography, party, or anything else.
What a Senate Race Costs
Senate races operate in a different financial universe. The median senator seeking reelection in 2024 raised about $11.1 million, but that median hides a wide range. In highly contested races, spending explodes. Senators Sherrod Brown and Jon Tester each raised over $90 million for their 2024 reelection bids, together accounting for nearly 30 percent of all Senate incumbent fundraising. Across all 266 Senate candidates in the 2023–2024 cycle, total receipts hit $1.5 billion.1Federal Election Commission.

State size matters. A Senate candidate campaigning in a state with several major media markets faces punishing broadcast ad costs and travel expenses that a single-market state doesn’t impose.
Where the Money Goes
Advertising dominates most campaign budgets. Television, radio, and digital ads frequently eat up more than half of total spending, and in competitive races the share climbs higher. The 2024 cycle saw nearly $4.5 billion in television and radio advertising across federal and gubernatorial races, with total ad spending likely exceeding $5 billion once digital is added. For a single House candidate in an expensive media market, even a modest TV presence can cost several hundred thousand dollars in a matter of weeks.
Staff salaries are usually the second-largest line item. A campaign manager, communications director, finance director, field organizers, and digital staff all draw salaries, and competitive races employ dozens of people. Consultants for polling, media production, and strategy typically charge monthly retainers or take a percentage of ad buys. Polling alone can run $30,000 to $50,000 per survey for a quality statewide poll in a Senate race.
Beyond ads and payroll, campaigns spend on:
- Travel: flights, hotels, rental cars, and meals for the candidate and advance staff, especially in geographically large Senate states
- Fundraising costs: event venues, catering, direct mail solicitations, and online platform fees, which can consume 20 cents or more of every dollar raised
- Field operations: office rent, phone banks, canvassing materials, and get-out-the-vote efforts in the closing weeks
- Legal and compliance: campaign finance attorneys and consultants who keep FEC filings accurate and on time
- Printed materials: yard signs, bumper stickers, literature drops, and direct mail pieces
The mix shifts by race. A Senate campaign with multiple expensive TV markets tilts heavily toward broadcast. A House campaign in a compact urban district trapped inside a giant metro market often shifts money away from television, since most of the audience lives outside the district, and puts more into digital and field.
What Drives the Cost Up or Down
Three factors move the number more than anything else.
Competitiveness. A safe seat is cheap; a toss-up is expensive. Most of the variation in campaign budgets traces back to this one variable.
Incumbency. Sitting members have a structural fundraising advantage. Corporate and union PACs overwhelmingly give to incumbents, name recognition lowers the cost of voter contact, and the franking privilege provides free constituent mail between elections. Challengers often have to spend heavily just to introduce themselves before they can start persuading anyone. Open-seat races, where no incumbent is running, tend to draw the most money from both sides because neither candidate has a built-in edge.
Media market. A House district sitting inside a major metropolitan TV market like New York or Los Angeles forces candidates to pay for ads that reach millions of viewers outside the district, making broadcast television inefficiently expensive. Senate candidates in states with multiple large metros face the same problem at scale.
What It Costs to Get on the Ballot
Before you spend a dollar on ads, there are entry costs. Most states charge a filing fee to appear on the primary ballot for the U.S. House, and those fees range widely, from under $100 in some states to over $10,000 in others. Some states let you submit voter petition signatures instead of paying a fee, and a handful require both. Senate filing fees follow a similar pattern and vary by state.
On the federal side, you become an official candidate in the FEC’s eyes once you raise or spend more than $5,000 in connection with a federal election. At that point you have 15 days to file a Statement of Candidacy (FEC Form 2) and designate a principal campaign committee, which registers using FEC Form 1. Every dollar raised and spent from then on falls under federal disclosure rules.2Federal Election Commission. Introduction to Campaign Finance and Elections
Testing the Waters Without Committing
You don’t have to register with the FEC just to see whether a run makes sense. Federal regulations allow a “testing the waters” period, during which you can raise and spend money on exploratory activities like conducting polls, making phone calls, and traveling to meet potential supporters without those funds counting as campaign contributions.3eCFR. 11 CFR 100.72 – Testing the Waters
There are limits. Money you accept still has to come from sources and in amounts that would be legal as campaign contributions, and you must keep records of every dollar received. Running public political ads promoting your candidacy, or raising money far beyond what exploratory activities would require, are signs you’ve crossed from exploring into campaigning. If you decide to run, every testing-the-waters dollar gets reported on your first FEC filing.
The Money You Don’t Control: Super PACs
The money candidates raise is only part of the picture. Independent expenditure-only committees, commonly called Super PACs, can raise unlimited amounts from individuals, corporations, and unions and spend freely to support or oppose candidates, so long as they don’t coordinate directly with a campaign.4Federal Election Commission. Contributions to Super PACs and Hybrid PACs In the 2023–2024 cycle, independent expenditure disbursements across all federal races totaled $4.4 billion.1Federal Election Commission. Statistical Summary of 24-Month Campaign Activity of the 2023-2024 Election Cycle
For a candidate, that outside money cuts both ways. Friendly groups can flood a district with ads on your behalf without you raising the money. You also have no legal control over their message, and opposing Super PACs can bury you in attack ads you never saw coming. In some competitive Senate races, outside spending exceeds what the candidates themselves spend.
The Bill After Election Night
Not every campaign ends in the black, and the race ending doesn’t end the obligations. A campaign committee cannot formally terminate and close its FEC account until every outstanding debt is paid, settled through a formal debt settlement plan, forgiven by the creditor, or otherwise extinguished.5eCFR. 11 CFR Part 116 – Debts Owed by Candidates and Political Committees A losing candidate can be stuck filing quarterly FEC reports for years while trying to retire debt. Creditors can forgive debts owed by ongoing committees, but only after the debt has been outstanding for at least 24 months and the committee can show minimal financial activity and little realistic prospect of paying.
Candidates who loaned their own money to the campaign have a somewhat easier path. After the Supreme Court’s decision in FEC v. Ted Cruz for Senate, there is no longer a federal cap on how much a campaign can repay a candidate for personal loans, removing a restriction that previously capped post-election repayment at $250,000.6Federal Register. Repayment of Candidate Loans Even so, you still need post-election contributions to repay yourself, and donors are far less motivated to give once the votes are counted. Running for Congress isn’t just what you spend by Election Day. It’s what you may still owe long after.
