How Does It Calculate?
We predict month-end costs in 3 simple steps
1Calculate Daily Average
First, we calculate your current sending pace.
Formula
Daily Avg = Total Messages ÷ Days Elapsed
Example
If you sent 1,000 messages by February 5th:
1,000 ÷ 5 = 200 msgs/day
2Predict Month-End Messages
Multiply the daily average by the total days in the month.
Formula
Prediction = Daily Avg × Days in Month
Example
Daily average of 200 msgs, February (28 days):
200 × 28 = 5,600 msgs
3Calculate the Cost
Calculate tiered charges for messages exceeding the free tier (30,000 messages).
Formula
Cost = Monthly Fee + Tiered Usage Charges
Example
Predicted 50,000 msgs, free tier 30,000 msgs:
Additional = 50,000 − 30,000 = 20,000 msgs
Additional cost = 20,000 × ¥3.0 = ¥60,000
Subtotal (excl. tax) = ¥15,000 + ¥60,000 = ¥75,000
Consumption tax (10%) = ¥75,000 × 0.1 = ¥7,500
Total (incl. tax) = ¥75,000 + ¥7,500 = ¥82,500
