I built a savings account comparator for Spain that ranks by real euros earned, not headline rate

Hi! Sharing a side project I've been working on. radartae.es compares high-yield savings accounts, fixed-term deposits and salary-account bonuses in Spain. The problem: most comparison sites rank by headline APY. But a 3% account capped at €50k earns less than a 2.5% uncapped one if you have €80k, and a 3-month promo rate isn't a yearly rate. So I rank by actual euros you'd earn in a year for your amount, after tax (Spain withholds 19%). Stack: static site generated with Python fr

AI 分析

痛点:西班牙储蓄账户比较网站通常按名义APY排序,忽略存款上限、促销期限和19%预扣税,用户难以知道实际到手利息。

目标用户:西班牙储户,尤其是有5万欧元以上存款、寻找高收益储蓄账户、定期存款或工资账户奖励的人。

证据:most comparison sites rank by headline APY. But a 3% account capped at €50k earns less than a 2.5% uncapped one if you have €80k, and a 3-month promo rate isn't a yearly rate. So I rank by actual euros you'd earn in a year for your amount, after tax (Spain withholds 19%).

变现:银行开户/存款导流佣金、CPA affiliate、展示广告、利率变动提醒或个性化推荐订阅。

MVP:选一个国家或地区,手动维护20到30个储蓄产品的JSON数据,用户输入存款金额和期限后,按税后实际年收益排序;用静态页+邮件提醒利率变化,先验证搜索流量和点击转化。

竞品:HelpMyCash、iAhorro、Raisin、Finect、Kelisto

摘要:西班牙开发者做了一个按税后实际欧元收益排序的储蓄账户比较器,覆盖55个产品并每月手动核对,技术栈为Python静态站、vanilla JS和Cloudflare Pages。原帖没有收入或用户付费证据,但存在银行导流佣金等变现空间;主要风险是已有多个比价平台且人工维护成本高。
