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

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.Deep dive into cache hit rate

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.
