How This Calculator Works
Enter the current drawn balance, the LOC's variable rate, and the fixed monthly payment. The calculator charges interest on the balance each month, subtracts the payment, and counts the months until the balance reaches zero. The calculator assumes you don't draw more during the payoff window.
The Formula
Debt Payoff Time
B = balance, P = fixed monthly payment, r = monthly rate (APR ÷ 12), n = months to clear
Worked Example
A $25,000 business LOC at 10% APR paid down at $600 a month clears in 52 months and adds about $5,838 in interest. Most LOCs require only interest-only minimum payments — at 10% on $25,000 that's $208 a month, which never touches principal. Always pay above the interest-only minimum to actually pay down the balance.
Key Insight
Business LOCs are designed for revolving use — borrow, repay, borrow again — not amortization. Treating one as a term loan and paying it off completely is fine, but it also locks up an asset (available credit) when the balance is zero. Some businesses keep a small balance to maintain active credit and demonstrate use for renewal; others zero out to minimize interest. Choice depends on your future capital needs.
Business LOC as working capital management
Healthy use of business LOC: bridge timing gaps between expenses (must pay suppliers, employees, inventory) and revenue (customer payments). Example: business sells $100K of products in Q4; collects from customers over 60 days. Q4 expenses (inventory purchased Q3, employee wages, rent) total $80K. Cash flow gap = $80K-$60K already collected = $20K bridge.
Use LOC for $20K bridge; pay back when customer receivables come in. Annual interest cost: $20K × 12% × (60 days / 365) = $400. Cost of avoiding cash flow crisis: minimal compared to revenue at risk.
Unhealthy use: LOC for ongoing operating losses (business unprofitable, using LOC to delay reckoning); LOC for owner draws (treating LOC as personal income); LOC for non-business purposes. These patterns produce growing balance with no clear payoff path.
Business LOC payback discipline
Best practice: clean the LOC to zero at least once per year. If business cannot fully repay LOC during normal seasonal cycle, it indicates the LOC is funding structural losses rather than timing gaps. Lender may not renew at expiration if balance never reaches zero.
For working capital LOC: target balance at year-end <30% of credit limit. Higher utilization suggests overdependence. Lender's renewal underwriting examines utilization patterns; consistent high utilization triggers concerns.
For inventory or seasonal-funded LOC: tie payments to revenue cycle (sell inventory; pay down LOC). Build payoff schedule into business plan, not as afterthought. Lender will accept higher utilization with clear payoff plan than with random/escalating utilization.
Business LOC sources and typical features (2024)
Reference business LOC providers and typical terms.
| Source | Limit range | Rate | Notes |
|---|---|---|---|
| SBA Express LOC (CAPLine) | Up to $5M | Variable | Government guarantee; longer term |
| Bank business LOC (Wells, Chase) | $25K-$500K+ | 9-13% | Traditional underwriting |
| Bluevine business LOC | $5K-$250K | 8-30% | Online; faster approval |
| OnDeck | Up to $100K | 29% effective | Speed over rate |
| Kabbage (Amex) | Up to $250K | 9-36% effective | |
| Credit union business LOC | $10K-$100K | 8-12% | Member benefit |
| Personal LOC for business use | $5K-$50K | 9-15% | Personal credit relied upon |
SBA-backed LOCs (CAPLine program) are the lowest-cost option but require SBA-eligible borrowing. Bank business LOCs are next-cheapest but require strong business financials and operating history (2+ years). Online lenders offer speed and easier qualification at higher rates — often 20-30%+ effective. For prime borrowers, traditional bank/credit union sources typically optimal.
Frequently Asked Questions
What's the minimum LOC payment?
Most business LOCs require interest-only minimum payments. On a $25,000 balance at 10% APR, that's roughly $208/month — which keeps the LOC current but never reduces principal. Pay above the minimum to actually pay down.
Should I pay off the LOC completely?
Depends on future capital needs. Zeroing out minimizes interest but locks up an asset (available credit). Maintaining active usage helps with renewal underwriting. Many businesses keep a small balance ($1,000 to $5,000) cycling through to demonstrate active use.
Can I redraw after paying down?
Yes — that's the structural difference between a LOC and a term loan. The LOC remains available up to the credit limit even after paydown. Term loans, once paid off, are gone.
What rate should I expect?
Bank business LOCs: prime + 1 to 3 points (currently 9% to 11.5%). Online business LOCs (Kabbage, Bluevine, OnDeck): often 15% to 30% effective APR. Fee structures vary and can push the true cost above the nominal rate.
Are LOC interest payments tax deductible?
Yes — interest on business debt is deductible against business income on Schedule C or the corresponding business return. The LOC must be used for business purposes; personal-use draws don't qualify.
When is this calculator unreliable?
When borrower continues drawing on LOC during 'payoff' (defeats the calculation), when LOC rate is variable and significant rate movements occur during payoff period, or when LOC structure includes renewal requirements that affect payback timing. For business LOCs specifically, target zero balance at least annually to maintain lender relationship and demonstrate healthy working capital management.

Methodology & Review
Business LOC payoff calculates time to clear business line of credit balance with fixed payments. The calculator returns payoff schedule. U.S. business LOC 2024: typical 9-15% APR variable; limits $25K-$500K secured by business assets or unsecured; common with banks (Wells Fargo, Chase, Bank of America business divisions) and online lenders (Bluevine, OnDeck, Kabbage). Used for working capital management — covering seasonal cash flow, inventory, AR fluctuations. RELIABILITY: Reliable for fixed-payment payoff modeling. Less reliable when borrower continues to draw on LOC during payoff (extending debt), when LOC rate is variable and changes during payoff period, or when minimum payments are interest-only with no principal reduction requirement.
