How It Works

Here’s a step-by-step guide to using the calculator:

1. Enter Your Information

  • Home price ($): The price of the home you want to buy (e.g., $400,000).
  • Down payment (%): The percentage of the home price you plan to pay upfront (e.g., 20%).
  • Current savings ($): How much you’ve already saved toward your down payment (e.g., $25,000).
  • Monthly contribution ($): The amount you can add to your savings each month (e.g., $1,500).
  • Annual interest rate (%): The annual rate your savings earns, if any (e.g., 4%).

2. Review Your Results

  • Down payment: The total amount you’ll need upfront, based on your inputs (e.g., $80,000).
  • Loan amount: The remaining amount you’ll need to borrow from a lender (e.g., $320,000).
  • Months to goal: How many months it will take to reach your down payment target, given your starting balance, monthly contributions, and expected interest (e.g., 33 months).

3. Explore Visual Summaries
