Hong Life CalculatorsHow it works
Cost per request = (uncached input tokens × input price + cached input tokens × cached-input price + output tokens × output price) ÷ 1,000,000, with prices in US$ per 1 million tokens. Requests made in off-peak hours cost half (factor 0.5), as DeepSeek states. Day = request cost × requests per day; month = day × days per month; year = month × 12. “Saved” compares with the same traffic at the plain input and output price. Prices shown are peak (full) rates. Cached input = cache hit. Taxes, tools (web search, code execution), image or audio tokens, long-context surcharges and cache-write fees are not included.

FAQ
When are DeepSeek’s off-peak hours?
DeepSeek’s peak hours are 01:00–04:00 and 06:00–10:00 UTC on weekdays (except Chinese public holidays). All other times are off-peak and cost half. In Korea (UTC+9) the peak windows are 10:00–13:00 and 15:00–19:00 on weekdays.
Why is the cached input price so low?
DeepSeek caches repeated prompt prefixes on disk automatically. A cache hit costs about 2–3% of the normal input price, so chat history and fixed instructions become very cheap.
Checked 10 Nov 2026. DeepSeek official API pricing page (https://api-docs.deepseek.com/quick_start/pricing), read on 10 Nov 2026. Off-peak rates are half of peak rates. Peak: 01:00-04:00 and 06:00-10:00 UTC, Monday to Friday (except Chinese public holidays).
