WhatsApp Business API Cost Calculator
The WhatsApp Business API has two costs that confuse almost everyone: the platform (BSP) subscription and Meta's per-conversation charge. This calculator combines both, plus GST, so you see your real monthly cost in India before you commit.
Platform fee
Rs.2,500
Meta conversations
Rs.1,760
GST (18%)
Rs.767
Total / month
Rs.5,027
Total = platform subscription + (conversations x Meta rate) + 18% GST. Meta's per-conversation charge is billed through your BSP and varies by category (marketing costs more than utility or authentication) and changes over time, so set the rate to match your mix and confirm current Meta rates. Free-tier conversations and service-window rules can lower your real Meta cost. Always confirm plan pricing on the provider's own site.
The two costs explained
1. The BSP platform subscription. Providers like AiSensy, Wati, Interakt and Gallabox charge a monthly fee for the shared inbox, broadcasts, chatbots and automation.
2. Meta's per-conversation charge. On top of the platform fee, Meta bills per 24-hour conversation, billed through your BSP. Rates vary by category (marketing costs more than utility or authentication) and change over time, so confirm current rates and set them in the calculator.

Frequently asked questions
- How much does the WhatsApp Business API cost in India?
- There are two costs: the BSP platform subscription (for example AiSensy from around Rs.2,500/mo, Gallabox from Rs.2,999/mo, DoubleTick from Rs.3,000/mo) and Meta's per-conversation charge billed through the BSP. Your total is platform fee + (conversations x Meta rate) + 18% GST. Use the calculator above with your real conversation volume.
- What are Meta's WhatsApp conversation charges?
- Meta bills per conversation, with rates that vary by category - marketing conversations cost more than utility or authentication, and service conversations within the 24-hour window are often free. India rates are relatively low but change over time, so set the per-conversation rate in the calculator to match your category mix and confirm current Meta pricing.
- Is the platform fee the only cost?
- No - and this is the most common mistake. The BSP subscription (AiSensy, Wati, Gallabox, Interakt, DoubleTick) is separate from Meta's per-conversation charges, which are billed on top through the BSP. A low platform fee can still mean a high total bill at high conversation volume, so always budget for both.
- Which WhatsApp Business API provider is cheapest?
- On platform fee, AiSensy (from around Rs.2,500/mo) is among the lowest, and it also has a free tier. But the cheapest in practice depends on your conversation volume, because Meta charges dominate at scale. Compare AiSensy, Wati, Interakt and Gallabox on both platform fee and your expected Meta cost.
