Best business loans for construction companies in 2026
The best financing for most construction companies is a business line of credit, because it covers materials and payroll between progress payments and costs nothing when it is not drawn. Equipment financing is the right tool for machinery, and an SBA 7(a) loan is the lowest-cost option for established contractors who can wait. Construction is the top industry by SBA 7(a) volume.

The short list

The 4 best options, ranked
1. Business line of credit Best for progress-billing gaps
You buy materials and pay crews weeks before a draw is approved, and retainage is held until the end. A line bridges each gap and is repaid when the draw lands.
Watch for: Some lenders add draw or maintenance fees, and a limit can be cut at renewal. Business line of credit guide →
2. Equipment loan Best for machinery and trucks
Skid steers, lifts, and work trucks secure their own financing, which keeps your line of credit free for the job costs that have no collateral behind them.
Watch for: Older or highly specialized equipment gets shorter terms and higher rates. Equipment financing guide →
3. SBA 7(a) loan Best for lowest long-term cost
For a contractor with two or more years of financials, a 7(a) loan funds working capital or an acquisition at capped rates and long terms.
Watch for: Heavy documentation, and the timeline rules it out for anything urgent. SBA loan guide →
4. Working capital advance Best for mobilizing on a job that starts now
When a signed contract needs materials on site next week and the bank cannot move that fast, an advance funds mobilization. Use it only when the job margin clearly covers the cost.
Watch for: The most expensive option on this list, and daily or weekly remittance strains thin margins. Working capital guide →
Side-by-side comparison
| Option | Verdict | Cost basis | Funding speed | Qualifies on |
|---|---|---|---|---|
| Business line of credit | Best for progress-billing gaps | Representative 8%–30% APR, charged only on what you draw | Often days | Revenue, time in business, and credit |
| Equipment loan | Best for machinery and trucks | Representative 8%–30% APR, with the term matched to the equipment's useful life | Days to weeks | The equipment is the collateral, which can offset a thinner credit profile |
| SBA 7(a) loan | Best for lowest long-term cost | Capped at 10.00%–13.50% by loan size (prime plus the SBA maximum spread) | Weeks to months | Generally stronger credit and two or more years in business |
| Working capital advance | Best for mobilizing on a job that starts now | Often a factor rate rather than an APR; compare total payback | As fast as 24 to 48 hours | Recent revenue and cash flow more than credit score |
What it costs
A line of credit charges interest only on the balance you have drawn. This is the monthly interest on a carried draw, before any principal is repaid:
| Carried draw | At 8% APR | At 19% APR | At 30% APR |
|---|---|---|---|
| $50,000 | $333 | $792 | $1,250 |
| $100,000 | $667 | $1,583 | $2,500 |
| $250,000 | $1,667 | $3,958 | $6,250 |

What lenders look at
- Your backlog and signed contracts, which show where repayment will come from.
- Receivables aging and how much of it is retainage that will not be paid until closeout.
- Bonding and insurance. A contractor who is bondable reads as lower risk to a lender too.
Mistakes to avoid
- Using a short-term advance to float a slow-paying general contractor for months. Match the financing to how long the money will really be out.
- Bidding a job that needs more working capital than your line and cash can cover.
Frequently asked questions
- What kind of loan is best for a construction company?
- A revolving line of credit fits the way construction cash flows: costs first, payment later. Add equipment financing for machinery so the line stays available for materials and payroll.
- Can construction companies use invoice factoring?
- Some can, through factors that specialize in construction, but progress billing, retainage, and lien rights make construction receivables harder to factor than ordinary invoices. A line of credit is usually simpler.
- How does retainage affect financing?
- Retainage is earned but unpaid until the project closes, so it ties up cash on every job. Lenders discount it when they look at your receivables, and it is one of the main reasons contractors need a line of credit.

Landon and Austin were greatLandon and Austin were great. Knowledgable and explained everything in a way that made it all really easy to understand. I avoid these call like the plague but these two were a joy to work with.
Highly recommendedHighly recommended! I worked with Corey, and he was awesome. He found an option after I received multiple rejections that no other company had presented to me. It was within my budget and my timeline. I'm so thankful!
BTC has become my go to for working…BTC has become my go to for working capital. Recently, my company was in a bind and needed funds. The BTC team, headed by Drew, took a problem solving approach and helped to overcome an initial denial, resulting in a better facility than the one I was turned down for. Thanks BTC! Thanks Drew!

How we ranked these options
This guide ranks types of financing, not individual lenders. Each option is ordered by how well it fits the need described on this page, judged on four things in this order: whether the structure matches how the money will be used and repaid, total cost, funding speed, and how hard it is to qualify. Cost figures are WithFunded calculations from published rate inputs as of November 2026: the bank prime loan rate from the Federal Reserve, the SBA maximum-rate schedule, and Federal Reserve survey data. The method follows our 2026 SMB Financing Cost Report, whose own figures use June 2026 rates.
WithFunded is a financing marketplace, not a lender. Our 2-minute form suggests a product type from the families we cover, and a funding partner reviews the request. Not every structure named in this guide is available through WithFunded: options such as SBA microloans, USDA farm loans, bank loans, and seller financing are ones you would pursue directly with the provider. They are listed because leaving out a good fit would make the ranking less useful.
