# Sort order

Most lists of Ideas or Solutions--including search results--use a default search order of either 🔥 *interest* or  🍬 *sweetness.*

## Ideas

### 🔥 Interest

The default sort order for Ideas is 🔥interest. 🔥Interest is the sum of the *shares* of all positions in an Idea. Shares are the amount contributed multiplied by a linear growth factor (called the *accrual rate*) and the number of cycles since the contribution.

$$
Shares\_{position} = contribution \* accrualRate \* (currentCycle - contributionCycle)
$$

$$
interest = \sum\_{i=0}^{numPositions - 1} shares\_{position\_i}
$$

## Solutions

### 🍬 Sweetness

The default sort order for Solutions is a hidden field called 🍬 *sweetness.* Sweetness connotes a good deal for Solution funders. Sweetness is calculated by multiplying the current amount 💎 staked in the Solution by the 🎁 funder reward percentage offered by the Solution drafter.

$$
sweetness = funder RewardPercentage \* stake
