Here just there are no miracles - simple mathematics. You need to know how many videos per month you release (if there are several channels, then in total from all channels) and multiply by how many languages you translate. Next, find the closest tariff plan. It is recommended to add 5-10% to the resulting figure. This will give you a little headroom to overwrite if necessary, as well as experiment with new languages.
If you have, for example, 1800 transfers, then the rate plan for 1500 is obviously not enough for you, and the next rate plan for 3100 transfers is too expensive. In this situation, it is recommended to buy a tariff plan for 1500 characters and use the functionality of one-time purchases. Or you can use the Creator Tools bonus program
