Stock split calculator

A company divides its existing shares into more shares. In a 4:1 forward split you get 4 shares for each 1 you own, each worth a quarter of the old price, so the total value stays the same. Companies often do this to make each share cheaper to buy.

It combines shares into fewer shares. In a 1:10 reverse split, every 10 shares become 1 share worth 10 times the price. Companies often do this to lift the share price, for example to meet an exchange's minimum.

Divide your cost per share by the split ratio. In a 4:1 split, $100 a share becomes $25. In a 1:10 reverse split, $5 a share becomes $50.

No. It changes the number of shares and the price per share, not your total value or your share of the company.

In the U.S., a split generally is not a taxable event, because your total value does not change. You adjust your cost per share and pay tax when you sell. Cash paid for fractional shares in a reverse split can be taxable.

You may keep the fraction or receive cash for it, depending on your broker. In a 1:10 reverse split, 15 shares become 1.5 shares: 1 whole share plus 0.5 kept or paid in cash.

The split itself changes nothing about the business, but it is often read as a warning sign because struggling companies use it to stay above an exchange's minimum price.

NVIDIA split 10-for-1 in June 2024 when its shares traded above $1,000. The split brought the price to around $120, which made a whole share easier to buy.
