Hours mean nothing without a rate
“Saves five hours a week” is a marketing sentence. Five hours at a $20 effective rate is $100 a month; at $80 it is $400. The converter attaches your own rate so the claim becomes a number you can compare against a subscription price.
Effective rate, not headline rate, is the right input — the same correction the net income checker applies.
The three-way comparison
Doing it yourself, automating it, and outsourcing it are competing options with different cost structures. Doing it yourself costs time; automating costs setup plus maintenance; outsourcing costs money per unit. Comparing them on the same axis makes the choice obvious.
The comparison also exposes the option people skip: sometimes the correct answer is to stop doing the task entirely.
没有费率，小时没有意义
“每周省五小时”是一句营销话术。按 20 美元的有效时薪算，五小时是每月 100 美元；按 80 美元算，是 400 美元。转换器挂上你自己的费率，让这句话变成一个能与订阅价格对比的数字。
该输入的是有效时薪而非表面报价——这正是净收入计算器所做的同一个修正。
三方对比
自己做、自动化、外包，是三种成本结构不同的竞争选项。自己做花时间；自动化花搭建加维护；外包按件花钱。放在同一坐标轴上比较，选择就很清楚。
这个对比还会暴露一个常被跳过的选项：有时正确答案是干脆不再做这件事。
