Loan & Debt Calculators

Debt is not inherently bad. A mortgage lets you build equity in a home. A student loan funds education that raises your earning power. The problem starts when you take on debt without understanding the full cost: how much you will actually pay over the life of the loan, how extra payments accelerate payoff, or how a small difference in interest rate changes the total by thousands of dollars.

The loan and debt calculators below give you that clarity. The loan payment calculator shows your monthly obligation and total interest for any fixed-rate loan. The mortgage calculator adds property tax, insurance, and PMI to give a realistic housing cost. The credit card payoff calculator reveals how long your balance will take to clear at different payment levels and shows how much interest you can avoid by paying even a little extra each month.

Every calculation runs locally in your browser. We do not see your balances, rates, or payment details. Run as many scenarios as you need to compare options and make the most informed decision. Understanding the math behind your debt is the first step toward controlling it.

Frequently Asked Questions

How are mortgage rates determined?
Mortgage rates are influenced by the federal funds rate, inflation expectations, your credit score, loan-to-value ratio, and overall market conditions. A higher credit score and larger down payment typically get you a lower rate. Even a 0.5% difference in rate can save tens of thousands over the life of a 30-year mortgage.
Should I pay off debt or save first?
It depends on the interest rate. If your debt charges more than you could earn investing (credit cards at 20%+ vs. investments at 7-10%), pay the debt first. For low-rate debt like mortgages (3-6%), it often makes sense to invest simultaneously. Always keep a small emergency fund even while paying debt.
Is refinancing my mortgage worth it?
Refinancing is typically worth it if you can reduce your rate by at least 0.75-1%, plan to stay in the home long enough to recoup closing costs, and the new loan term fits your financial plan. Use the mortgage calculator to compare monthly payments before and after refinancing.
What is the fastest way to pay off credit card debt?
Two proven strategies: the avalanche method (pay minimums on all cards, put extra money toward the highest-rate card first) saves the most interest. The snowball method (smallest balance first) builds psychological momentum. Both beat paying only minimums, which can take decades to clear a balance.
What is a good debt-to-income ratio?
Lenders generally prefer a DTI below 36%, with no more than 28% going to housing costs. Above 43% you may struggle to qualify for most mortgages. A lower DTI means you have more room in your budget and are less vulnerable to financial shocks.
