What this calculator tells you
The Loan Affordability Calculator helps translate amount, APR, term, payment, or debt inputs into a planning estimate. Use the output to compare scenarios, not as a lender quote.
Limitations
Calculator results do not include every lender fee, state rule, underwriting condition, payment timing variation, optional product, or final disclosure. Actual terms come only from the lender or partner reviewing a request.
Compare next
| If the result shows | Compare next |
|---|---|
| Payment looks high | Try a smaller amount, lower APR assumption, or longer term while checking total cost. |
| Total interest looks high | Compare a shorter term or extra-payment strategy. |
| Debt ratio looks tight | Review affordability before adding another payment. |
| Two offers look close | Compare APR, fees, net proceeds, due date, and total repayment. |
Quick answer: This calculator estimates a proposed personal-loan payment, debt-to-income ratio before the loan, debt-to-income ratio after the proposed payment, total repayment, and estimated interest. It is educational only and does not predict approval.

Borrow Your Loan is not a lender and does not decide approval, funding, loan amount, APR, or terms. A lender or partner controls any actual offer.
What this calculator can and cannot tell you
| Output | How to use it | Important limitation |
|---|---|---|
| Estimated payment | Check whether a payment may fit your monthly budget. | Real lender terms may include fees or different payment timing. |
| DTI before and after | See how a possible payment changes debt pressure. | Lenders may calculate or interpret DTI differently. |
| Total repayment | Compare payment fit with total cost. | This estimate excludes lender-specific fees unless you include them in the amount. |
Illustrative affordability scenario
Illustrative example - not an offer - actual terms vary. This example uses $5,000 gross monthly income, $900 in existing monthly debt, and a hypothetical $10,000 loan at 18% APR over 36 months. It does not say the borrower can afford or qualify for a loan.
| Gross monthly income | Existing monthly debt | Proposed payment | DTI before | DTI after |
|---|---|---|---|---|
| $5,000.00 | $900.00 | $361.52 | 18.0% | 25.2% |
This example produces an estimated payment of $361.52 and would change the illustrative DTI from 18.0% to 25.2%.
Methodology
The payment estimate uses the fixed-installment amortization formula. Current DTI is current monthly debt divided by gross monthly income. Proposed DTI adds the estimated payment to current monthly debt. Zero APR is handled by dividing principal by term.
