DeepSeek API Cost Tracker
Track Every Cent of Your DeepSeek API Spend
Drop your DeepSeek billing CSVs and get instant cost breakdowns by day, model, and API key — all processed locally in your browser. No signup, no server upload.
Features
Daily Cost Breakdown
See exactly how much you spent each day with an interactive bar chart. Spot anomalies and spending spikes at a glance.
Per-Key Cost Attribution
Know which API key is burning through your budget. Detailed per-key tables with inline usage bars and copy-to-clipboard support.
Cache Hit Rate Monitoring
Understand how much you save through context caching. Green/amber/red color coding makes it easy to spot low-hanging optimization opportunities.
Multi-Month Comparison
Drag multiple ZIP files at once and they auto-pair by month. Compare spending trends across billing cycles to track your optimization progress.
Real Usage Scenarios
Finance or ops review
Upload the monthly export before invoice review. The dashboard highlights daily spikes, zero-cost anomalies, and which keys drove the change.
Client or project chargeback
If one DeepSeek account serves multiple apps or customers, use the per-key and custom-project views to map spending back to each internal owner.
Optimization rollback checks
After changing prompts, routing rules, or cache settings, compare multiple months side by side to verify whether the optimization actually reduced spend.
Cost Tracking FAQ
Why use a CSV cost tracker if I already have the DeepSeek billing page?
DeepSeek's billing view is useful for raw exports, but this tool restructures the data into daily trends, per-key attribution, cache hit visibility, and project-level summaries.
Who should review this page every month?
Usually the engineer who owns prompts, the team lead who tracks burn, or the operations person who reconciles invoice deltas. The page is meant for those handoff moments.
Can I use it for post-optimization proof?
Yes. Upload two or more months and compare daily and per-key changes. That makes it easier to tell whether a prompt rewrite or caching improvement actually reduced cost.
DeepSeek API 费用追踪器
追踪 DeepSeek API 的每一分钱
拖入 DeepSeek 账单 CSV，即刻获取按日、按模型、按 API Key 分类的费用明细 — 所有数据在浏览器本地处理。无需注册，无需上传。
功能特点
每日费用明细
通过交互式柱状图精确查看每日支出。一眼发现异常消费和费用尖峰。
按 Key 费用归因
搞清楚到底是哪个 API Key 在吞噬预算。详细到 Key 的表格包含内嵌用量条和一键复制功能。
缓存命中率监控
全面了解上下文缓存为你节省了多少成本。绿色/琥珀色/红色三色标记，让你轻松发现最值得优化的 API Key。
多月对比分析
一次拖入多个 ZIP 文件，自动按月份配对合并。跨账单周期对比消费趋势，追踪你的优化成果。
典型使用场景
财务或运营月度复盘
在核对账单前上传月度导出，快速定位每日费用尖峰、异常归零以及到底是哪几个 Key 推高了支出。
客户 / 项目分摊结算
如果一个 DeepSeek 账号服务多个应用或客户，可借助按 Key 与自定义项目视图，把费用回溯到具体内部负责人。
优化方案回归验证
改了 Prompt、路由策略或缓存配置后，直接横向比较多个月份，验证这次优化是否真的把成本压下来了。
费用追踪常见问题
既然 DeepSeek 后台已经有账单页，为什么还需要 CSV 成本追踪器？
平台账单页适合导出原始数据，但这个工具会把数据重组为每日趋势、按 Key 归因、缓存命中可见性和项目级汇总，更利于定位问题和复盘。
谁最适合每月看这页？
通常是负责 Prompt 的工程师、关注 burn rate 的团队负责人，或对账单差异做核对的运营同学。这页就是为这些交接时刻准备的。
它能用于证明一次优化真的有效吗？
可以。上传两个月或更多月份的数据，对比每日与各 Key 的变化，就能更直观看出 Prompt 改写或缓存优化是否真的降低了成本。
