House Down Payment Savings Calculator
House Down Payment Savings Calculator
A down payment goal starts with simple arithmetic — home price times your target percentage (commonly 20% to avoid mortgage insurance, though many loans allow less). This calculator then applies the same savings-plan math used for any goal to find your required monthly contribution.
Prospective homebuyers use this to set a realistic house-hunting timeline: if the required monthly savings amount doesn't fit the budget, extending the timeline or targeting a lower down payment percentage are the two main levers.
- Two-Step Calculation: First derives your dollar down payment goal from the home price and percentage, then solves for the monthly savings needed.
- 20% Isn't Mandatory: Many conventional loans allow down payments as low as 3-5%, though a lower down payment usually means mortgage insurance and a larger loan.
- Existing Savings Help: Money you've already saved reduces the future monthly amount needed, since it compounds on its own in the meantime.
Do I really need 20% down?
No — many conventional and government-backed loans allow down payments well below 20%, though a smaller down payment typically means private mortgage insurance (PMI) and a bigger loan-to-value ratio.
Should I keep down payment savings in a savings account or invest it?
For a near-term goal (a few years or less), a high-yield savings account or CD is generally safer than market investments, since you can't afford a market downturn right before you need the money.
