Your total interest on a $100,000 mortgage

On a 30-year mortgage with a 4% fixed interest rate, you’ll pay $71,869.51 in interest over the life of your loan. That’s about two-thirds of what you borrowed in interest.

If you instead opt for a 15-year mortgage, you’ll pay $33,143.83 in interest over the life of your loan — or about half of the interest you’d pay on a 30-year mortgage.

Amortization schedule

When you take out a mortgage, you agree to pay the principal and interest over the life of the loan. Your interest rate is applied to your balance, and as you pay down your balance, the amount you pay in interest changes.

Amortization means that at the beginning of your loan, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your balance.

Will I need a down payment?

It depends on the type of loan.

VA loan

Backed by the Department of Veteran Affairs (VA), VA loans don’t require a down payment. To qualify for a VA loan, you or your spouse must have served 90 to 181 days in active service, or over six years in the Reserves or National Guard. The VA also extends loans to borrowers with a family member who died in the line of duty.

Conventional loan

Lenders typically require a down payment of at least 20%. So, for a $100,000 mortgage, you’d need a down payment of $20,000 – excluding closing costs and taxes. Some conventional lenders will accept down payments as low as 3%, but you’ll most likely need to purchase private mortgage insurance (PMI) to secure the loan.

FHA loans

Insured by the Federal Housing Administration, these loans require a down payment of at least 3.5%. For a $100,000 mortgage, that means you’ll cough up $3,500. The down payment aside, you’ll pay an upfront mortgage insurance premium, and then continue to make monthly payments until you build 20% equity in your home.

USDA loans

Another type of government loan, USDA loans are backed by the US Department of Agriculture. They don’t demand a down payment, but you’ll need to carry private mortgage insurance (PMI) until you’ve built up 20% equity in your home.

Can I afford a $100,000 mortgage?

Ideally, you want to make sure your mortgage payment doesn’t exceed 28% to 30% of your monthly household income. To comfortably afford a $100,000 mortgage, you’ll need to make the minimum monthly incomes outlined below based on your down payment.
