A household earning the U.S. median income and saving ten percent of it takes roughly eight years to accumulate a twenty percent down payment on a median-priced home, assuming the home price stays still. Home prices do not stay still. That single assumption is what separates a savings plan from an arithmetic exercise, and it explains why the timeline feels different from the way it is usually described.
Below are the timelines by income, the sources behind every input, and the assumptions that drive the results.
The inputs, and where each comes from
Four figures do all the work here. Each is attributed, and readers should check them against the original series rather than against this article.
Median home sale price: roughly $400,000 to $420,000 in 2024, from National Association of Realtors and Census Bureau data. The calculations below use $410,000 as a midpoint.
Median household income: roughly $80,000 as of 2023, from the U.S. Census Bureau. This is household income, covering all earners in the home, not an individual salary.
Twenty percent down payment on $410,000: $82,000. Twenty percent is not a legal requirement. It is the conventional threshold above which private mortgage insurance is typically dropped.
Five percent down payment on $410,000: $20,500, shown alongside because most first-time buyers put down less than twenty percent.
Timelines at a twenty percent target
These are straightforward division, using gross income and a stated savings rate. They are arithmetic, not survey findings.
At a $60,000 household income saving 10 percent, or $6,000 a year, reaching $82,000 takes about 13.7 years. Saving 15 percent, or $9,000 a year, takes about 9.1 years.
At $80,000 saving 10 percent, or $8,000 a year, the figure is about 10.3 years. At 15 percent, or $12,000 a year, about 6.8 years.
At $100,000 saving 10 percent, about 8.2 years. At 15 percent, about 5.5 years.
At $140,000 saving 10 percent, about 5.9 years. At 15 percent, about 3.9 years.
Timelines at a five percent target
The same incomes against $20,500 produce far shorter timelines. At $60,000 saving 10 percent, about 3.4 years. At $80,000, about 2.6 years. At $100,000, about 2.1 years. At $140,000, about 1.5 years.
The gap between these two tables is the real content of the article. Moving the target from twenty percent to five percent cuts the timeline by three quarters, which is why most first-time buyers do it, and why mortgage insurance is so common.
What these numbers leave out
Every figure above is optimistic, for four reasons worth stating plainly.
They use gross income. Federal, state and payroll taxes come out first. A household saving ten percent of gross is saving a considerably higher share of what actually reaches its account.
They assume the price holds still. If home prices rise while a household saves, the target moves. A saver accumulating $8,000 a year against a target rising even modestly is climbing a slope, and at high enough appreciation the target outruns the saver entirely.
They ignore closing costs. Those commonly run a few percent of the purchase price on top of the down payment, which adds thousands to the real target.
They assume nothing interrupts. A decade of uninterrupted saving with no job loss, medical event, car replacement or family change is not a typical decade.
Why the savings rate is the hard part
Ten percent of income sounds achievable in the abstract. The competing claims are what make it difficult.
KFF put the average total premium for employer-sponsored family coverage near $25,000 a year in 2024, with the worker’s share above $6,000. Child Care Aware reports center-based childcare commonly running $10,000 to $17,000 or more per child per year. Edmunds and Experian data put the average new-car payment near $730 to $740 a month in 2024, with used vehicles near $520. The Education Data Initiative puts average student loan debt near $38,000 per borrower, and Federal Reserve G.19 data puts total outstanding student debt in the range of $1.7 to $1.77 trillion.
Set the worker premium share, one child in center-based care, and a used-car payment against an $80,000 household income and a substantial share of gross income is committed before housing, food or saving. The residual is where the down payment has to come from.
And that residual is being extracted in the same market where the household intends to buy, because rent tracks local home prices. The more expensive the target market, the more it takes from the saver while they save.
The ratio underneath all of it
The reason these timelines look worse than they did for earlier generations is a single ratio. A median home at roughly $410,000 against median household income near $80,000 is about five times income. In the 1980s the comparable figure sat near three times.
At three times income, a twenty percent down payment is roughly sixty percent of one year’s household income. At five times, it is roughly one full year. The savings problem did not get harder because households became less disciplined. The target grew relative to the income available to reach it.
Fight For A Living Wage, a nonpartisan grassroots 501(c)(3), makes the affordability case on this basis, treating housing as one of several costs that outran wages rather than as an isolated market.
How to use these figures
Substitute your own numbers. National medians are close to useless for an individual decision, because both home prices and incomes vary enormously by county. The MIT Living Wage Calculator exists partly because basic cost requirements differ by location to a degree national data obscures.
Run your own local median price against your own household income at your own realistic savings rate, using net income rather than gross. The result will be less encouraging than the tables above and considerably more accurate.
What the national figures establish is the shape of the problem, not its size in any particular place. The shape is that the down payment target has grown faster than the incomes expected to reach it, and no savings rate fully compensates for a change in that ratio.
