购车负担能力计算器

你到底能负担多贵的车?

经销商和放贷方会批准给你一辆超出你预算承受能力的车。这个计算器先套用20/4/10法则,再对照你的真实月度预算进行核对——销售税、按你信用等级计算的贷款利息,以及保险,全部计入。

Real-life monthly expenses

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

You can actually sustain up to

$209,824

Your budget can support at least as much as the 20/4/10 rule's ceiling — the rule of thumb isn't what's holding you back here.

常见问题

根据我的收入,我能负担多贵的车?

作为起点,这个计算器使用20/4/10法则:首付至少20%,贷款期限4年(48个月)或更短,车辆总成本(贷款月供加保险)不超过税前月收入的10%。这就是“舒适”档位。“紧绷”和“高风险”会放宽这个上限,就像本站其他计算器会放宽超出放贷方理想比率一样——但放宽比率并不会让你的银行账户跟着变大,这正是结余收入检验存在的原因。

什么是20/4/10法则?

这是购车时一条常被引用的个人理财经验法则:首付至少20%,贷款期限不超过4年,车辆月度总成本(月供加保险)不超过税前月收入的10%。它不是一项贷款监管规定——而是一条保守的准则,这个计算器用它作为“舒适”档位的基准。

这个计算器包含销售税和保险吗?

包含。销售税是用你所在州的典型综合税率,乘以车价减去以旧换新价值后的金额计算得出,再连同购车总价减去首付和以旧换新部分一起计入贷款。月度保险费是一项直接输入项,因为保费会因驾驶员、车辆和地区差异过大,无法用一张表格估算出来。

购车贷款负担能力计算器和经销商或放贷方会批准的额度有什么不同?

经销商或放贷方的金融部门核查的是你是否符合贷款资格,而不是这笔月供是否会给你的预算留出空间去应付其他开支。这个计算器两者都算:大多数个人理财指南推荐的20/4/10式规则,以及一个单独的结余收入测试,会扣除你的其他债务和真实月度支出,来看这笔月供是否真的能够承受。二者之间的差距,才是值得关注的数字。
