住房负担能力计算器

一套房子每个月实际会花掉你多少钱

房贷月供并不是拥有一套房子的全部成本。这个计算器在本金、利息、税费、保险和PMI之上,加上了几乎每个人都会忘记的一项——维护储备金,让你看到的数字就是你实际要支付的数字。

Income & debts
Real-life monthly expenses ?

Lenders don't count these against you — but they determine whether the payment actually fits.

Your result

Comfortable — up to $267,424

A lender would likely approve up to

$335,507

You can actually sustain up to

$462,699

Your budget can support at least as much as a lender's generous debt-to-income ceiling — the DTI limit isn't what's holding you back here.

True monthly cost
$2,463

Left over each month after this payment, other debts, and real-life expenses

$2,037

This household clears both the lender's ratios and a real monthly budget.

What's driving this

  • Your $1,300/mo in childcare, healthcare, groceries, and other real-life expenses doesn't affect what a lender will approve, but it directly reduces what's left over each month.
  • Texas property tax at 1.63% is costing you roughly $141/mo more than the national average would suggest.
  • Homeowner's insurance in Texas is costing you roughly $141/mo more than the national average would suggest.

常见问题

为什么会有一项我没要求的维护费用?

因为这是拥有一套房子真实且无法回避的成本,而大多数计算器都悄悄把它去掉,好让数字看起来更小。这个计算器默认按房屋价值的1%每年计入预算——屋顶、热水器和暖通空调系统坏掉的时候,可不会挑一个方便的时机。

PMI什么时候会取消?

只要首付低于20%,就需要缴纳私人房贷保险。根据联邦法律,一旦贷款余额摊销到房屋原始价值的78%,PMI就会自动取消——这个计算器会直接展示这一确切发生的月份,而不是假装PMI是永久成本,也不是假装它根本不存在。

15年期还是30年期更划算?

15年期的利率更低,积累房屋净值的速度也快得多,但在相同贷款金额下,月供明显更高。在计算器中切换贷款期限,就能看到针对你具体数字的月供和总成本差异。

如果我首付不到20%会怎样?

你需要一直缴纳PMI,直到贷款价值比降到78%以下——这个计算器会把它作为月度明细中单独的一项列出来,同时还会告诉你需要额外增加多少首付才能完全跳过它。

在买房之前,我需要多少住房负担能力?

在你买房之前,先在这里核算你的数字,而不是等到放贷方的柜台前才算。住房负担能力不仅仅是放贷方会批准的价格——它是在计入税费、保险、PMI和维护费用之后,你的预算仍然留有余地的那个价格。这个计算器会同时展示两个数字,让你用自己的数字去谈判,而不是对方的数字。
