Compare monthly payments, total interest, and flexibility between 15-year and 30-year home loans.
Try the Mortgage CalculatorMonthly payment vs total cost
A 30-year mortgage spreads payments over 360 months, keeping the monthly bill lower. A 15-year mortgage doubles the payment timeline pressure but cuts total interest dramatically — often by half or more on the same loan amount and rate.
The right choice depends on cash flow, other financial goals, and how long you plan to stay in the home. Lower payments free cash for investments or emergencies; shorter terms build equity faster.
When a 30-year loan makes sense
Choose 30 years when you need maximum affordability, expect income to grow over time, or want flexibility to invest extra cash elsewhere. You can still pay extra toward principal without committing to the higher required payment of a 15-year loan.
First-time buyers in high-cost markets often start with 30-year terms to qualify within debt-to-income limits, then refinance or make extra payments as income increases.
When a 15-year loan makes sense
A 15-year mortgage suits buyers with stable high income, strong savings, and a goal of owning the home free and clear sooner. You will pay less total interest and build equity faster — useful if you are nearing retirement or want to eliminate housing debt early.
Run both scenarios in our calculator with your actual home price and rate spread (15-year rates are typically 0.25–0.75% lower than 30-year) to see the exact tradeoff.
