Line of Credit Pros and Cons

Share

NEED MONEY BEFORE PAYDAY? GET UP TO $250

A personal line of credit gives you access to a reusable amount of money that you can borrow when needed. You only pay interest on the amount you actually use.

The flexibility can make a line of credit useful for emergencies and irregular expenses. The downside is that interest rates are often variable, and easy access to credit can make it easier to stay in debt.

KOHO Cash Advance

KOHO Cover is not a traditional payday loan. It is a cash advance designed for Canadians who need a smaller amount of money to cover short term expenses.

With KOHO Cash Advance, you can:

  • Get up to $250 as an instant cash advance (amount depends on eligibility)

  • Pay no interest on the advance

  • Avoid a credit check

  • Repay automatically once you add money or get paid

You subscribe to the Cover bundle for a low monthly fee, and in return you get the advance feature plus extras like a credit report, financial coaching, and priority support.

Pros of a Personal Line of Credit

1. You Only Pay Interest on What You Borrow

One of the biggest advantages is that you do not need to borrow your entire approved limit.

If you have a $10,000 line of credit but only use $1,500, interest is generally charged on the $1,500 balance.

This can make a line of credit useful when you do not know exactly how much money you will need.

2. You Can Reuse the Credit

A personal line of credit is revolving.

When you repay what you borrowed, your available credit increases again.

You usually do not need to submit a new loan application every time you need money.

This can make a line of credit useful for recurring or unpredictable expenses.

3. It Can Help With Unexpected Expenses

A line of credit can provide access to money when an unexpected cost appears.

You might use one for:

  • Car repairs

  • Emergency home repairs

  • Vet bills

  • Medical expenses

  • Temporary income gaps

  • Other necessary expenses

Having credit available can reduce the need to apply for a new loan during an emergency.

4. Interest Rates Can Be Lower Than Credit Cards

Personal lines of credit can sometimes offer lower interest rates than traditional credit cards.

Your actual rate depends on the lender and your credit profile.

A lower rate can reduce your borrowing cost if you need to carry a balance.

That does not automatically make a line of credit cheap. Always check the actual rate you are offered.

5. You Have Flexibility Over How Much You Borrow

A personal loan usually gives you one lump sum.

A line of credit lets you withdraw only what you need.

This can be useful for projects where costs happen gradually.

For example, a home renovation may involve several expenses spread across a few months.

Cons of a Personal Line of Credit

1. Interest Rates Are Often Variable

Many personal lines of credit have variable interest rates.

This means your rate can rise or fall over time.

If rates rise while you are carrying a balance, your borrowing cost can increase.

This makes payments less predictable than some fixed-rate loans.

2. Easy Access Can Lead to Overspending

A line of credit can feel like money sitting in your account.

It is still debt.

Because the credit remains available, it can be tempting to use it for purchases you would not otherwise make.

Repeated borrowing can turn a temporary balance into long-term debt.

3. Minimum Payments May Pay Down Debt Slowly

Your lender requires a minimum payment each month.

Depending on the product, the minimum may cover only a relatively small portion of the principal.

Paying only the minimum can keep you in debt for a long time.

If your payment only covers interest, you will not reduce the amount you originally borrowed.

4. Your Credit Can Be Affected

A line of credit is part of your credit profile.

Late or missed payments can hurt your credit history.

High balances can also increase your credit utilization.

Managing the account responsibly is important if you want to maintain healthy credit.

5. There May Be Fees

Some lines of credit can include:

  • Administration fees

  • Registration fees

  • Account fees

  • Transaction fees

Fees depend on the lender and product.

Review the agreement before accepting a line of credit.

6. It Can Make It Easier to Stay in Debt

Because you can borrow again after repaying part of the balance, a line of credit does not have the same natural ending as a traditional instalment loan.

You could repay $1,000 and then borrow it again.

Without a repayment plan, the debt can continue for years.

Personal Line of Credit vs. Personal Loan

A personal loan provides a lump sum of money upfront.

You normally repay it through scheduled payments over a specific term.

A line of credit is more flexible.

You borrow only what you need and can borrow again as you repay the balance.

A personal loan may make more sense when you:

  • Know exactly how much you need

  • Want predictable payments

  • Want a specific repayment date

A line of credit may make more sense when you:

  • Do not know exactly how much you will need

  • Expect expenses at different times

  • Want reusable access to credit

  • Can repay balances quickly

What Can You Use a Personal Line of Credit For?

Personal lines of credit can generally be used for many different purposes.

Common uses include:

  • Emergency expenses

  • Home improvements

  • Car repairs

  • Education expenses

  • Temporary cash-flow gaps

  • Debt consolidation

You typically do not need to tell the lender exactly how every dollar will be spent.

How Does Interest Work on a Line of Credit?

Interest starts when you borrow money from the line of credit.

You continue paying interest until the borrowed amount is repaid.

Suppose you borrow $3,000.

You pay interest on that outstanding $3,000 balance.

As you repay the principal, the amount generating interest decreases.

The faster you repay the balance, the less interest you generally pay.

Does an Unused Line of Credit Cost Money?

Not necessarily.

You generally do not pay interest if your balance is $0.

Some providers may still charge account or administration fees.

Check the terms of your specific line of credit.

Is a Personal Line of Credit Good for Emergencies?

It can be useful as a backup source of money.

A line of credit may give you quick access to funds without requiring a new loan application each time an emergency occurs.

That does not mean you should rely on credit instead of savings.

An emergency fund lets you cover unexpected expenses without paying interest.

For smaller short-term expenses, a cash advance may also be an option. KOHO Cover provides eligible Canadians with up to $250 without interest or a credit check.

Should You Use a Line of Credit to Pay Off Credit Cards?

It can make sense if the line of credit has a meaningfully lower interest rate.

You could use it to consolidate higher-interest balances into one account.

However, transferring debt does not solve the problem if you continue adding new balances to your credit cards.

You need a repayment plan.

Otherwise, you could end up with both credit card debt and line-of-credit debt.

Is a Personal Line of Credit Worth It?

A personal line of credit can be useful if you want flexible access to money and can repay what you borrow responsibly.

Its main advantages are reusable credit and paying interest only on what you actually use.

Its main disadvantages are variable rates and the risk of carrying debt indefinitely.

Before opening one, compare the interest rate, fees and minimum payment requirements. Make sure the credit limit fits your budget rather than simply accepting the largest amount available.
