Characters, not minutes
Voice platforms meter characters, so a script with long words and numbers costs more than the same duration of simple prose. Estimating by finished minutes hides this; estimating by characters exposes it before you commit to a plan.
The estimator also divides total cost by finished minutes, which is the number you actually need when pricing client work.
Tier cliffs and the commercial floor
Subscription tiers are not linear. Crossing a character threshold can double your bill, and the commercial-license floor is often one tier above the free plan. Both effects are included so the comparison reflects what you will really pay.
If your monthly output is uneven, compare an annual plan against paying per project rather than assuming the subscription is cheaper.
按字符计费，不是按分钟
配音平台按字符计费，所以长单词和数字多的脚本，比同样时长的简单文字更贵。按成品分钟估算会掩盖这一点，按字符估算则能在你定计划之前暴露它。
估算器还会把总成本除以成品分钟数，这正是给客户报价时真正需要的数字。
阶梯跳档与商用门槛
订阅档位不是线性的。跨过某个字符阈值，账单可能翻倍；而商用授权门槛往往比免费版高一档。两种效应都计入结果，使比较反映你实际要付的钱。
如果月产量不稳定，请把年付方案与按项目付费对比，而不是默认订阅更便宜。
