“How much can I get?” is the first question almost every owner asks — and the honest answer is the one nobody wants to hear: it depends on your business, not on a number you can look up. There’s no published limit that applies to you specifically, because a credit limit isn’t a price tag. It’s a lender’s judgment call about how much your business can comfortably repay.

I spent years on the lender side of the desk setting those limits. So instead of repeating a “you can get up to $X” headline, let me walk you through exactly what a lender weighs to land on your number, where the typical limit ranges sit by lender type, and the unvarnished truth about chasing the big amounts — $100k, $250k, $500k, and the $1M line everyone wants to know about.

This page is part of our guide to business line of credit requirements.

The short answer

Your credit limit is a lender’s estimate of how much debt your business can service — pay back, on time, from real cash flow — without putting itself (or them) at risk. The bigger and steadier your revenue, the longer your track record, and the cleaner your credit, the higher that estimate goes.

A few things to internalize before we get into the mechanics:

• There is no universal cap. Limits vary enormously by lender and by your profile. Anyone quoting you a fixed maximum without seeing your financials is guessing.
• A higher limit isn’t automatically better. Lenders extend what the numbers support. A limit that’s larger than your cash flow can responsibly carry is a liability, not a win.
• You usually don’t pick the number — the lender does. You can ask for a target, but the underwriting decides what you actually get approved for.

What determines your credit limit

When I sized a line, I wasn’t looking at one number — I was building a picture from five inputs. Here’s what each one does to your limit.

1. Revenue

This is the anchor. Lenders frequently size a line of credit as a fraction of your annual or monthly revenue, because revenue is the raw material that repayments come out of. More revenue generally supports a larger line. The exact relationship — what percentage of revenue a lender is willing to extend — varies by lender and product.

2. Cash flow

Revenue tells a lender what comes in; cash flow tells them what’s left after the business pays its own bills. Two companies with identical revenue can support very different limits if one runs on thin margins and the other keeps healthy cash on hand. Lenders read bank statements to see whether money flows in consistently and whether there’s room to service a new payment. Steady, predictable deposits push your limit up; choppy or seasonal cash flow pulls it down. (If your revenue swings by season, our guide to seasonal cash flow lines is worth a read.)

3. Time in business

A longer operating history lowers the lender’s risk, and lower risk supports a higher limit. A business with years of records and a proven ability to repay is a safer bet than one that opened last quarter — even at the same revenue. Thin-file and brand-new businesses tend to be capped lower until they build a track record. (See business lines of credit for startups and new businesses.)

4. Credit (personal and business)

Your credit profile sets the terms of the deal, and it influences the ceiling too. Stronger personal credit — and, as the business matures, a stronger business credit file — generally unlocks larger limits at better pricing. Weaker credit doesn’t always disqualify you, but it tends to compress both the limit and the cost. We cover this in depth in what credit score you need.

5. Collateral

Whether you pledge collateral is the dividing line between two kinds of lines:

• Unsecured lines aren’t backed by a specific asset, so lenders lean harder on revenue, cash flow, and credit — and tend to keep limits more conservative.
• Secured lines are backed by collateral (receivables, inventory, equipment, or cash). Because the lender has something to fall back on, secured lines can often support larger limits for the same business. The trade-off is that you’re putting an asset on the line. Our secured vs. unsecured guide breaks down which makes sense.

Almost all small-business lines also carry a personal guarantee — you personally stand behind the debt. That’s part of how lenders get comfortable extending the limit in the first place.

Typical limit ranges by lender type

Here’s the landscape at a glance. Treat every figure as “varies by lender” until verified against that lender’s live page — the value of this table is the relative ordering, not exact dollar amounts.

Typical line-of-credit limits by lender type (illustrative)

Lender type	Typical limit range	What it takes	Trade-off
Traditional bank / credit union	Highest limits — commonly up to ~$500k*, sometimes more for strong profiles	Strong revenue, multi-year history, solid credit, often collateral	Largest limits, lowest cost, slowest and hardest to qualify
SBA-backed lending (e.g. CAPLines)	Up to $5M via government backing*	Solid profile + heavy documentation	High limits, low cost, longest timeline, most paperwork
Online / fintech lender	Lower to mid-range — often up to ~$250k* (e.g. Bluevine ~$250k; OnDeck up to ~$100k*)	More flexible profile; faster underwriting	Smaller limits, easier and faster, higher cost
Marketplace (e.g. Lendio)	Spans the range — matches you to many lenders	One application, profile-dependent	No single cutoff; you see what multiple lenders will actually offer

* Illustrative — ranges above reflect representative published lender limits and SBA program maximums (e.g. Bluevine up to ~$250k; OnDeck up to ~$100k; SBA CAPLines up to $5M; per the lenders’ and SBA’s published figures, 2026). Specific limits, rates, and terms vary by lender and by your full business profile — always confirm against the lender’s own current terms before relying on a number.

How to qualify for a higher limit

If the limit you’re being offered is smaller than you need, the lever isn’t a better pitch — it’s a stronger file. Here’s what actually moves the number, in roughly the order of impact I saw on the lender side:

1. Grow and document revenue. Since limits often scale with revenue, the most direct path to a bigger line is more revenue — and clean records that prove it. Make sure your bank statements and bookkeeping tell a clear, consistent story.
2. Strengthen cash flow. Tightening up margins, smoothing out lumpy deposits, and keeping a cash cushion all signal that you can service a larger payment. Lenders reward businesses that don’t run on fumes.
3. Put time on the board. A few more quarters of operating history and on-time payments can shift you out of the thin-file tier. If the need isn’t urgent, time itself raises your ceiling.
4. Improve your credit profile. Paying down existing balances — especially short-term, high-cost debt like a merchant cash advance — frees up capacity and improves the credit picture. Building a business credit file helps as the company matures. Start with how to build business credit.
5. Consider collateral. If an unsecured line caps out below what you need, a secured line backed by receivables, inventory, or equipment can often support a higher limit — provided you’re comfortable pledging the asset.
6. Don’t bet on one lender’s box. Two lenders can look at the same business and land on very different limits. Checking multiple lenders at once shows you the top of your actual range, not just the first offer you happened to get.

One caution: ask for what the business can carry, not the biggest number you can squeeze out. A line you can’t comfortably repay isn’t a higher limit — it’s a faster way to get into trouble. Run the payment math before you commit with our line of credit calculator.

The reality of large amounts: $100k, $250k, $500k, $1M

This is where the honest talk matters most, because the bigger the number, the bigger the gap between what owners hope for and what lenders actually do.

The pattern is simple: as the requested amount climbs, the bar climbs with it — fast. A larger line means more risk to the lender, so they demand more proof you can carry it: more revenue, more history, cleaner credit, stronger cash flow, and often collateral and deeper financial documentation (tax returns, financial statements, sometimes a review of your accounts receivable).

Roughly how the difficulty scales:

• Around $100k. Reachable for an established business with solid, documented revenue and decent credit — but it’s a real underwriting decision, not a rubber stamp. For reference, several online lenders top out around this level (OnDeck up to ~$100k*), and qualifying typically lines up with their published floors (roughly $100k+ annual revenue, ~1 year in business*). Thin-file or low-revenue businesses will usually land below this. Exact thresholds vary by lender.
• $250k–$500k. Now you’re in serious-underwriting territory — above where most online lenders cap (Bluevine tops out around $250k*) and into bank/SBA range. Expect lenders to want strong multi-year history, substantial and consistent revenue, healthy cash flow, good credit, and very possibly collateral, plus deeper documentation such as tax returns and financial statements. This is where a lot of applications get scaled down to what the financials support. Specifics vary by lender.
• $1,000,000 and up. A seven-figure line is genuinely hard. At this level you’re typically looking at bank lending or an SBA-backed facility — the SBA’s CAPLines program runs up to $5M* — generally for larger, well-established businesses with significant revenue, multiple years of clean financials, strong credit, and — very often — collateral and a full financial-statement review. It’s not impossible, but it is not something a young or modest-revenue business gets, and no honest lender will promise it sight-unseen. Specific qualifying thresholds vary by lender and program.

The takeaway: the limit follows the financials, not the request. If you’re aiming high, the work is in the business — revenue, history, cash flow, credit, and often collateral. And because lenders disagree on where the line sits, the smartest move when you’re chasing a large amount is to let several of them weigh in at once rather than betting everything on a single underwriter.

The verdict

There’s no lookup table for how much you can get — your limit is a lender’s estimate of what your business can responsibly repay, built from revenue, cash flow, time in business, credit, and collateral. Banks and SBA-backed lending reach the highest limits but demand the most; online lenders move faster for smaller amounts; marketplaces let you see what several lenders will actually offer.

If you want a bigger number, build a stronger file — and be honest with yourself about what you can carry. The big headline amounts ($250k, $500k, $1M) are real, but they’re earned with years of clean financials and usually collateral, not unlocked with the right application wording.

The practical move: don’t guess your limit, and don’t bet it all on one lender’s read. Check where your business actually lands against multiple lenders in one application — you’ll see your real range instead of a number off a webpage.
