Calculate timeline to save for your down payment with compound interest
Future homebuyers currently saving for a down payment, renters planning a timeline to homeownership, and anyone trying to reach a savings goal faster.
Calculate how long it takes to reach your down payment goal with your current savings rate, and see how investment growth compounds to accelerate your timeline.
Saving $1,500/month toward a $60,000 down payment (15% on $400K) at 4.5% interest reaches the goal in 36 months instead of 40 months — 4 months faster thanks to compounding.

Plan your path to homeownership in 4 simple steps
Enter the home price you're targeting and your desired down payment percentage. We'll calculate the exact dollar amount you need to save.
Input how much you've already saved and how much you can contribute each month. Be realistic — consistent saving beats aggressive targets you can't maintain.
Enter the APY on your savings account. High-yield savings accounts currently offer 4-5% APY, which significantly shortens your timeline through compound interest.
See exactly when you'll reach your goal, how much interest you'll earn, and the total cash needed including closing costs. Adjust inputs to explore different scenarios.
Your down payment is the foundation of your home purchase. It determines your loan amount, monthly payment, whether you'll pay private mortgage insurance (PMI), and even the interest rate you'll qualify for. A larger down payment means lower monthly costs and more equity from day one.
While 20% down is the traditional target that eliminates PMI, many first-time buyers purchase with as little as 3-3.5% down. The key is finding the right balance between saving enough to get favorable terms and not waiting so long that rising prices outpace your savings.
Everything you need to know about saving for your first home
3.5% FHA minimum, 5% conventional, 20% to avoid PMI. On $400K: 3.5% = $14K, 20% = $80K. Start with what you can, refinance later to remove PMI.
Use HYSA earning 4-5% APY. On $50K saved earning 4.5% = $2,250/year interest. Much better than checking (0.01%) or regular savings (0.5%).
Saving $80K at $2,000/mo takes 3.5 years with 0% interest, but only 2.8 years at 4.5% APY. Interest earned: $6,200! Use compound interest to your advantage.
Parents/family can gift down payment. Need gift letter stating it's not a loan. FHA allows 100% gift, Conventional requires 5% your own funds for investment property.
Many states offer down payment assistance (DPA) grants or low-interest loans. Some give $5K-25K free money. Check your state housing authority website.
Automate savings the day after payday. Set up separate HYSA so you're not tempted to spend it. Treat it like a bill you must pay - to your future self!

Why save 20%?
Reality check: Most first-time buyers put down 6-12%. Don't wait years for 20% if prices rising faster than you can save.
Best options for down payment savings:
1. High-Yield Savings Account (HYSA) - BEST CHOICE
Example: Saving $60K over 2 years
2. Money Market Account
3. Short-term CDs (if timeline flexible)
AVOID for down payment:
Yes, but be very careful. Here are your options:
IRA Withdrawal (Best option if using retirement funds):
401(k) Loan (Risky but common):
401(k) Hardship Withdrawal (Last resort):
Example comparison - $30K needed:
Option A: IRA withdrawal
Option B: 401(k) loan
Option C: Save longer
Recommendation: Only use retirement funds if you have no other option and are confident in job security.
Usually NO - don't wait for 20% if it takes years. Here's why:
Scenario: $400K home, saving $2,000/month
Option A: Buy with 5% down ($20K) = 10 months saving
Option B: Wait 3 more years to save 20% ($80K)
The math: Option A wins by $138,000!
When you SHOULD wait for 20%:
PMI isn't forever:
Yes! Gift funds are commonly used and fully allowed.
