According to IDF reports, Iran launched 181-200 ballistic missiles at Israel this past Tuesday

Around $200 million is a hefty sum for a missile barrage and certainly not an insignificant portion of Iran's missile stockpile.
However, from Tehran's perspective, it represents a relatively light hit to their finances.
According to a Reuters report, Iran has managed, even under international sanctions, to export oil worth $35 billion annually

This missile barrage cost them the equivalent of just two days of exports
1. not something they would do daily,
2. but also not an expense the country would struggle to manage every few months,
3. especially while neglecting other branches of the military to invest in missile technology.
