Loans & Debt Education

Understanding your loans & debt numbers

Interest & APR

Interest is the cost of borrowing. APR includes certain fees, so it reflects the true yearly cost of a loan better than the interest rate alone.

Loan Term

A longer loan term lowers each monthly payment but increases total interest paid over the life of the loan for the same amount and rate.

Payoff Strategies

The avalanche method targets the highest-interest debt first to save the most interest; the snowball method targets the smallest balances first for momentum.

Debt-to-Income

DTI compares monthly debt obligations to gross monthly income and is a key figure lenders use when evaluating new credit applications.

Loans & Debt Calculator FAQs

Common loans & debt questions, answered

How is a loan payment calculated?

With the amortization formula M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the principal, r is the monthly rate, and n is the number of monthly payments.

What's the difference between interest rate and APR?

The interest rate is the cost of borrowing the principal. APR includes certain fees expressed as a yearly rate, so it usually better reflects the total cost of a loan.

Does paying extra on a loan help?

Yes. Extra payments apply to principal, which reduces future interest and shortens the term — often significantly over the life of the loan.

What is debt consolidation?

Combining multiple debts into a single new loan, often to simplify payments or lower the overall interest rate. It changes the structure of debt but does not erase it.

Snowball or avalanche — which payoff method is better?

The avalanche method (highest interest first) saves the most interest. The snowball method (smallest balance first) can help build momentum. The best choice is the one you'll stick with.

What is a good debt-to-income ratio?

Lender standards vary, but a lower DTI is generally better. Many lenders look for a total DTI below a certain threshold when evaluating new credit. This calculator shows your ratio for your own planning.
