Personal loan calculators

By the Carolina Personal Loans editorial team · Last reviewed and updated October 28, 2026 · How we write and check

Short answer

These three calculators run in your browser and store nothing. Use the consolidation tool to see whether a new loan costs less than your current balances, the DTI tool to see how a new payment fits with your other debts, and the offer table to compare up to three written quotes.

Debt consolidation break-even

Consolidation break-even calculator

Enter your own numbers. We do not supply or estimate any rate for you.

Enter numbers to see the comparison.

Estimates for comparison only. Your lender's Truth in Lending disclosure is the legal source for APR, payment and total cost.

Debt-to-income ratio

Debt-to-income (DTI) calculator

DTI is your monthly debt payments divided by gross monthly income (CFPB definition). Lenders set their own limits.

Compare up to three offers

How to use the results

The consolidation calculator tells you whether a new loan would cost less overall than your current balances. The DTI calculator shows how a new payment might sit alongside your other payments. Lenders look at both. Sample numbers in each calculator are placeholders, and the tools do not send your entries anywhere.

Carolina budget examples

A household in Raleigh earning $5,200 a month before taxes pays $1,550 in rent, $320 for a car and $140 in card minimums. Debts total $2,010 and the ratio is about 39 percent. A $200 new payment would take it to about 42 percent. A household in Fayetteville with $3,800 income and $1,100 in rent has less room for the same payment. Enter your own numbers to see where you stand.

Using the offers table

Enter three real offers. For each, type the amount you would receive, the number of payments and the payment amount. The table calculates total repaid and the cost over what you receive. In the Carolinas, you may see offers from credit unions, online lenders and local finance companies. If a local finance company quotes a payment that seems low, check the term; a long term can cost more in total.

What to do with the results

If the consolidation result shows a saving, confirm the numbers with a written offer. If DTI is above what you are comfortable with, reduce the amount or pay down debts first. Then use the checklist to verify lenders.

Storm-season tip

If you live where hurricanes are a risk, run a second DTI with a higher expense line for insurance deductibles and repairs. If the ratio looks tight, borrow less.

How the formulas work

The consolidation calculator estimates the time and total interest to repay your current debts using the balances, rates and payments you enter. It then compares that with a loan offer, counting the fee as part of the cost. The debt-to-income calculator divides your total monthly debt payments by your gross monthly income. The offer table subtracts the amount you receive from the total repaid for each offer. No score or credit data is used.

Practice problems

Problem 1. You owe $4,000 on a card at 25 percent with a $120 minimum, and $2,000 on another at 20 percent with a $60 minimum. A loan offer gives you $5,700 after a $300 fee and asks $230 a month for 30 months. Enter all figures and compare totals.

Problem 2. Your gross income is $4,500 a month. Rent is $1,300, a car payment is $350 and card minimums are $180. What is your ratio, and what happens if a new $250 payment is added?

Problem 3. Three offers: A receives $9,500 and repays $12,300; B receives $10,000 and repays $13,100; C receives $9,800 and repays $12,500. Which costs least over what you receive?

The numbers are illustrations to practice with. They are not offers.

Reading the results with caution

A saving of a few dollars is not worth a new account; look for a meaningful difference. A debt-to-income ratio above the high 30s or low 40s percent may make approval harder with many lenders, but each sets its own limit. Use the offers table only with written quotes. If a number looks too good, ask the lender to explain every fee.

Share your results

If a counselor or family member is helping you, you can screenshot the results to discuss. Remember that the numbers stay in your browser.
