Front-End DTI
Also known as: housing ratio, front ratio
The percentage of gross monthly income consumed by housing costs alone (rent or mortgage principal, interest, taxes, and insurance). Most personal loan lenders use back-end DTI rather than front-end DTI, but understanding both helps when managing total borrowing capacity near a home purchase.
Full definition
Debt-to-income (DTI) ratio has two versions used in lending: Front-end DTI = Housing costs only / Gross monthly income. Housing costs include: mortgage principal and interest (or rent), property taxes, homeowner's insurance, HOA dues, private mortgage insurance (PMI). Standard limits for mortgage approval: conventional loans generally allow front-end DTI up to 28%. FHA loans allow up to 31%. Back-end DTI = All recurring monthly debt payments / Gross monthly income. Adds all other minimum payments: car loans, student loans, credit cards, personal loans, child support, alimony. Standard limits: conventional mortgages allow up to 36-45% (sometimes higher with compensating factors). Personal loan lenders use back-end DTI almost exclusively. Why front-end DTI matters for personal loan borrowers: If you plan to buy a home within the next 1-2 years, taking on a personal loan raises your back-end DTI and may push you past mortgage qualification thresholds. Example: You earn $6,000/month. Your target home has a $1,500/month PITI payment (25% front-end DTI, acceptable). But a $500/month personal loan payment raises your back-end DTI from 30% to 38.3%, which may affect mortgage approval. Understanding front-end DTI helps you plan personal borrowing around a future home purchase without jeopardizing mortgage qualification.

- APR (Annual Percentage Rate)APR is the yearly cost of borrowing, expressed as a percentage of the loan amount. It includes interest plus most lender fees, so it's a more complete measure of cost than the interest rate alone.
- Interest rateThe interest rate is the percentage of the loan balance charged per year as interest, excluding fees. It is a component of, but smaller than, the APR.
- Fixed interest rateA fixed rate stays the same for the entire life of the loan, so the monthly payment never changes. Most U.S. personal loans are fixed-rate.
- Variable interest rateA variable rate can change over the life of the loan, usually tied to an index like the prime rate. Monthly payment can rise or fall.
- Prime rateThe prime rate is the benchmark interest rate U.S. banks publish for their most creditworthy commercial customers. Many consumer rates are quoted as prime + a margin.
- Loan termThe loan term is how long you have to repay the loan, usually expressed in months. Common personal-loan terms are 24, 36, 48, 60, and 72 months.
