# Auto-Compound

Francium will help you reinvest your profit to boost your APY.

LP tokens staked in Raydium will a earn profit continuously. Making use of the profit will greatly increase the capital efficiency.

The formula to reference is:

$APY = (100\%+\frac{R}{N})^N$

In which, R is the APR, N, the compound frequency, is how many times we reinvest per year.

This can also be reduced when N is much larger than R:

$APY = ((100\%+\frac{R}{N})^\frac{N}{R}) ^{R}\to e^{R}$

Francium offers the best compound performance by maintaining the reinvest interval around 15 minutes to balance the gas fees and efficiency.
