# Variable: expense

```ts
const expense: object & Typed<{
  amount: {
     amount: string;
     currency: string;
  };
  date?: string;
  note?: string;
  owedBy?: readonly string[];
  paidBy: string;
  split?: readonly object[];

```

Defined in: [packages/core/src/schemas/library/money.ts:27](https://github.com/leifriksheim/minca/blob/main/core/src/schemas/library/money.ts#L27)

An expense someone paid for a group, and how it splits. Every version is
kept, since who changed an amount matters when settling up.
