If a plan or policy is uncosted, the cost of it has not been calculated in a detailed way.

This promise of free musical tuition is uncosted and it is unclear whether the Treasury is offering any new money for it. 这个提供免费音乐课的承诺并未作成本核算，目前尚不清楚财政部是否会为此提供新的资金。

We will not make uncosted spending promises, but assess what needs to change and how we can do better. 我们不会做出未核算成本的开销承诺，而是会评估需要改变与改进之处。
