Save Your Down Payment Faster
Figure out exactly how much to save each month to reach your down payment goal. Set a target home price, down payment percentage, and current savings – the tool will map out your savings timeline and monthly contribution needed. All free, private, and instant.
Turn Your Homeownership Dream Into a Savings Plan
Saving for a down payment can feel overwhelming, but breaking it into a monthly goal makes it manageable. This calculator takes your target home price, the down payment percentage you want to reach, and what you’ve already saved, then shows exactly how much you need to put away each month — and how long it will take. Whether you’re aiming for a conventional 20% down or a smaller FHA 3.5% down payment, you’ll see a clear path to the closing table.
What Is a Down Payment Calculator?
A down payment calculator is a free online tool that helps future homebuyers plan their savings. You enter your desired home price, the down payment percentage (or a fixed dollar amount), your current savings, and an expected savings interest rate, and the calculator will determine the monthly contribution you need to make, as well as the number of months or years until you reach your goal. It’s the perfect companion to a mortgage calculator — because before you can finance a home, you need to save for it.
How to Use the Down Payment Calculator
Set Your Home Price Goal
Enter the price of the type of home you want to buy. The calculator will automatically determine a target down payment based on your chosen percentage.
Enter Your Current Savings
How much have you already saved? Even a small starting amount shortens your timeline.
See Your Monthly Contribution
Instantly find out how much you need to save each month — and how long it will take to reach your target.
How the Down Payment Calculator Works
The tool uses the future value of a series formula, taking into account your starting savings, monthly contributions, and an assumed interest rate on your savings. It solves for the monthly payment needed to reach the target amount in a given time, or for the time needed given a fixed monthly contribution. All calculations are performed in your browser, so your financial information never leaves your device.
Core Savings Formula
Future Value = P(1+r)^n + C × [ (1+r)^n – 1 ] / r
P = current savings, C = monthly contribution, r = monthly interest rate, n = number of months.

Down Payment Percentages for Different Loans
Conventional Loan
Typically 5–20%. A 20% down payment avoids Private Mortgage Insurance (PMI), saving you hundreds each month.
FHA Loan
As low as 3.5% with a credit score of 580+. You’ll pay mortgage insurance, but the lower upfront cost makes homeownership accessible sooner.
VA & USDA Loans
Often require 0% down for qualified borrowers. If you’re eligible, you might not need this calculator — but it’s still useful for moving costs and reserves.
How Your Savings Rate Changes Everything
A small increase in monthly savings can dramatically shorten your timeline. For example, if you need $40,000 and have $5,000 saved, saving $500/month at 0% interest will take 70 months (nearly 6 years). Bump that to $700/month, and you’ll reach your goal in 50 months — over a year and a half sooner. The calculator lets you play with these numbers to find a sustainable pace.
Interest on Savings: A Hidden Accelerator
Without Interest
If you keep your down payment in a checking account earning 0%, your timeline depends purely on how much you save each month. Every dollar counts.
With Interest (High‑Yield Savings)
A high‑yield savings account paying even 3–4% can shave months off your timeline, especially for longer savings horizons. The calculator factors this in automatically.
Don’t Forget Closing Costs
While you’re saving for a down payment, remember that closing costs typically add 2–5% of the home price. You can use the calculator to save for a combined “down payment + closing costs” goal. Simply add the estimated closing cost amount to your target down payment figure and enter the total as your goal.
PMI and the 20% Threshold
If your down payment is less than 20% on a conventional loan, you’ll pay Private Mortgage Insurance. The calculator can show you how much longer you’d need to save to reach 20% versus 5%, helping you decide whether it’s worth waiting to avoid PMI. Often, the PMI savings outweigh the extra months of saving.
Example Savings Plan
You’re aiming for a $300,000 home with a 10% down payment ($30,000). You’ve already saved $6,000 and can contribute $800/month to a high‑yield savings account earning 3% annually. The calculator determines you’ll reach your goal in approximately 27 months (2 years and 3 months). If you increase your monthly savings to $1,000, the timeline drops to 22 months — five months faster. This real‑time feedback helps you adjust your budget before you even start house hunting.
Where to Park Your Down Payment Savings
Your down payment fund should be safe and liquid — not invested in stocks if you plan to buy within 5 years. A high‑yield savings account, money market account, or short‑term CD are excellent options. The calculator lets you input an expected interest rate, so you can see how much faster a 4% return helps compared to a 0.01% checking account.

The math follows standard time‑value‑of‑money formulas and is accurate to the cent. As long as your inputs are realistic, the projected timeline and monthly contribution will be precise.
Security and Privacy
All calculations are performed locally in your browser. No personal financial data is ever sent to a server, stored, or shared. You can even use the tool offline after the page loads.

Frequently Asked Questions
How much should I save for a down payment?
It depends on the loan type. Conventional loans often require 5–20%, FHA loans as low as 3.5%, and VA/USDA loans may require 0%. A larger down payment avoids PMI and reduces your monthly payment.
Can I include closing costs in the calculator?
Yes. Add your estimated closing costs (2–5% of home price) to your down payment target and enter the total as your goal. The calculator will show a single timeline for the combined amount.
Does the calculator account for interest on my savings?
Yes. You can input an expected annual interest rate (such as from a high‑yield savings account) and the tool will compound it monthly to give a more accurate timeline.
What if I can’t reach 20%?
That’s okay — many buyers put down less. The calculator shows you the timeline for any percentage. Just be aware you may pay PMI until you reach 20% equity.
How often should I update my savings plan?
Every 3–6 months, or whenever your income, expenses, or home price target changes. Regular check‑ins keep you on track.
Is my personal data safe?
Absolutely. Everything is calculated locally. No data is ever transmitted or stored.
