Why annualization matters
A 4.99 weekly plan is roughly 259.48 per year before tax. Users often compare the weekly number with a yearly unlock and pick the wrong option. Convert every offer to the same time base first.
How to estimate real subscription cost
Weekly prices look small until they are annualized. This calculator converts weekly, monthly, and yearly plans into comparable monthly and yearly totals so you can decide whether a trial or paid plan matches your actual usage.

Count only active plans
Paused, cancelled-but-not-expired, and family-shared plans can confuse totals. Mark only the plans that still create real spend. Keep notes for trial end dates and cancel paths.
Local privacy by design
Rows are stored in browser localStorage only if you click save. Export JSON for spreadsheets. Nothing is uploaded to Storewise servers.
What this tool cannot do
It cannot read your Apple account, cancel subscriptions, or include tax automatically. Always confirm final amounts and renewal dates in Settings > Apple ID > Subscriptions and the App Store checkout page.
Recommended workflow
1) list every recurring plan, 2) annualize cost, 3) open the matching checklist, 4) cancel low-value plans, 5) re-check next week. Pair this page with paid-vs-subscription and subscription-fatigue articles.
如何估算真实订阅成本
周付价格在换算成年成本前看起来总是很小。这个计算器把周付、月付和年付统一成可比较的月成本与年成本，帮助你判断试用或付费方案是否匹配真实使用。
为什么要做年化
4.99 的周付方案在税前大约等于每年 259.48。用户常拿周价格和年付解锁直接比，结果选错。先把所有报价换算到同一时间基准。
只统计仍在花钱的方案
已暂停、已取消但未到期、以及家庭共享方案容易干扰总数。只勾选仍产生真实支出的项目，并用备注记录试用结束日和取消路径。
本地隐私设计
只有点击保存时，列表才会写入浏览器 localStorage。可导出 JSON 到表格工具。数据不会上传到 Storewise 服务器。
这个工具做不到什么
它不能读取你的 Apple 账户、不能取消订阅，也不能自动计入税费。最终金额和续费日期请到“设置 > Apple ID > 订阅”和 App Store 结算页确认。
推荐流程
1）列出全部循环方案；2）年化成本；3）打开对应清单；4）取消低价值项目；5）下周复查。建议配合“买断 vs 订阅”和“订阅疲劳”文章一起使用。
How to use this page safely
- Skim the overview, then run the tool.
Use the interactive section for the task at hand, then come back to the detailed guide if the result looks incomplete or high-stakes.
- Treat partial API data as a clue, not a final answer.
Empty results, delayed feeds, or region mismatches can happen. Re-check the App Store, Apple ID settings, or the original source before you act.
- Verify prices, trials, refunds, and permissions officially.
Storewise helps you research faster. Billing and account outcomes still depend on Apple’s screens and policies.
- Open related checklists for expensive or hard-to-reverse decisions.
Paid apps, free trials, family devices, and region switching are safer with a short written checklist.
