Pricing

Cost = File Size × Duration × Rate

SOL Amount = USD Cost ÷ Current SOL Price

USDFC Amount = USD Cost

File size: 50 MB = 52,428,800 bytes
Duration: 30 days
Rate: 3 × 10⁻¹² USD/byte/day

Cost in USD = 52,428,800 × 30 × 0.000000000003
           = $0.0047 (less than half a cent!)

At $120/SOL:
Cost in SOL = $0.0047 ÷ $120
           = 0.000039 SOL
           = 39,000 lamports
