Worked examples

$350,000 home price, 20% down ($70,000 target) starting with $20,000 at $1,500/month

To save 20% ($70,000) on a $350,000 house starting with $20,000 saved and adding $1,500 monthly at 4.5% APY takes 31 months, earning $2,389 in interest.

$500,000 home price, 10% down ($50,000 target) starting with $10,000 at $2,000/month

Reaching $50,000 with $10,000 saved at $2,000/month takes ~19 months.

Frequently asked questions

Why is a 20% down payment recommended for home purchases?

A 20% down payment eliminates Private Mortgage Insurance (PMI), lowers monthly payments, and builds instant home equity.

Can I buy a house with less than 20% down?

Yes, conventional loans permit as low as 3% down, FHA loans require 3.5% down, and VA/USDA loans offer 0% down for eligible borrowers.

Where should I store my down payment savings?

Keep down payment funds in high-yield savings accounts (HYSA), certificates of deposit (CDs), or money market funds to keep capital safe while earning interest.
