Down Payment Calculator
Down payment amount, loan and resulting monthly payment.
How it works
Down = price × %; Loan = price − down
Common down payments are 20%–30%. Low down payments may add insurance or a higher rate.
Worked example
Price 1,000,000 with 30% down: 300,000 down, 700,000 loan.
At 20% down: 200,000 down, 800,000 loan — borrowing 100,000 more adds about 489/month and 76,000 of interest at 4.2% over 30 years.
Notes and limitations
More down is not automatically better: it consumes liquidity and emergency reserves. A common rule is to keep six months of expenses after paying the down payment. Also budget 3%–8% of the price for taxes, fees and setup costs.
