This calculator is intended for illustration purposes only and exact payment terms should be agreed with a lender before taking out a loan.
A business line of credit is like a fuse between a loan and a credit card for businesses. It’s a flexible option for financing that gives businesses access to funds up to a set credit limit. Unlike a traditional loan where the entire amount is disbursed at once, a line of credit allows you to take out funds as needed.
Then, interest is only charged on the amount you use, making it a great choice for managing cash flow, covering unexpected expenses, or financing short-term business needs. Many times, these are used to bridge gaps between receivables (incoming funds) and payables (what needs to be paid), so you keep smooth daily operations.
The Swoop line of credit calculator is an online tool that helps you estimate the monthly payments as well as how long it will take to pay off the credit line used. Our aim is to help you understand what it takes to pay back your line of credit debt before it’s used.
Start by entering your balance (current or estimated), then your interest rate and your payoff goal, which is the number of months you’d like to pay it off in. Finally, enter your monthly payment, and the ‘your results’ will populate.
From here you can see what your projected monthly payment should be to reach you payoff goal as well as how it compares to your current monthly payment.
The easiest way is to see your terms and conditions provided by your lender but to do it by hand you’ll need access to a few things including; you interest rate, the total principal banace and how long you’ll take to repay.
Here’s how it works:
So if you borrow $50,000 at 8% annual interest for 30 days, the interest would be about $328.77.
Repayments on a line of credit typically include both principal and interest. Each repayment reduces the outstanding balance, and since interest is only charged on what you owe, your future payments decrease as you pay down the balance.
For example, if you have a line of credit with a limit of $100,000 and borrow $50,000, your monthly repayment will cover the interest on the $50,000 plus any principal amount you choose to pay. If you pay $10,000 toward the principal, your interest for the next month will be calculated on the remaining $40,000. This repayment flexibility helps manage costs while keeping your borrowing within your financial means.
No, but you can use the calculator to see how long it will take you to pay off a line of credit, which is just as helpful. To estimate how much you can borrow on a line of credit, you would need to speak with a lender. Each has its own ways of determining who is eligible for which amounts. Things to consider checking for yourself include:
If a line of credit doesn’t fit your business’s needs, consider alternative funding options. For starters, equity financing allows you to raise capital by selling shares in your business. Then invoice financing lets you borrow against unpaid invoices to free up cash flow.
Another option is peer-to-peer lending platforms that can provide fast loans with flexible terms. Additionally, crowdfunding is a viable option for businesses with innovative products or community-driven missions.
