API vs Claude Pro+SDK - Should You Switch?

Plug in your current monthly Claude API spend and how heavily you use Agent SDK / Claude Code. See whether switching to a subscription helps once the SDK carve-out takes effect.

Effective 2026-06-15

Your situation

Current monthly Claude API spend (USD) From your last Anthropic invoice. Round to nearest $10. How much of that spend is agent / Claude Code traffic?

Light Medium Heavy

Light = ~15% agent (mostly batch/chat API). Medium = ~50%. Heavy = ~85% (most spend is agentic). Plan to compare against Team Standard seats: $20 SDK credit. Enterprise Standard seats: NOT eligible. Billing cycle

Monthly Annual

Annual saves 20% on Team plans (e.g., Team Premium $125→$100/seat). Interactive Claude value realized: 50% 0% = pure automation. 50% conservative. 100% = full chat allowance valued at retail.

medium agent usage

Medium agent usage — credit largely consumed, overflow at full API rates.

Cost-roughly-neutral on cash; gain interactive Claude as bonus. Consider Max 5x ($100 credit) if your agent spend is climbing.

**Pro** saves $10/month ($120/year) when you value interactive Claude at 50%. Cost-roughly-neutral on cash; gain interactive Claude as bonus. Consider Max 5x ($100 credit) if your agent spend is climbing.

Methodology + caveats

SDK credit is a CARVE-OUT not a discount: prepaid voucher at full API rates, not a rate reduction
Agent overflow (beyond SDK credit) bills at standard API rates per Anthropic docs
Non-agent API spend (interactive Claude Code, chat) always at full API rates
Pre-June-15: Pro/Max subsidized agent usage 15-30× cheaper than API; post-June-15 this subsidy ends
Agent intensity (light/medium/heavy) drives default split; override via monthly_agent_sdk_spend_usd
Multi-seat plans scale plan cost and SDK credit by num_users; Team plans require min 5 seats
