Short answer

Many startups authorize 10,000,000 shares with a par value of $0.00001 and issue most of them to founders. At that par value, 8,000,000 founder shares cost $80 in total. In Delaware, filing with the assumed par value capital method usually keeps the yearly franchise tax near $400.

How this tool works

Founders buy their shares at par value. The rest stays unissued for future hires, advisers and investors. The Delaware estimate uses the same rules as our franchise tax calculator.
