Here is a spreadsheet that uses the latest coin prices from coinmarketcap to calculate how many $/day will be payed out per $ invested for a given payout rate. Additionally, enter a hashrate and it will calculate the required investment along with daily, weekly, monthly and yearly $ payouts. Currently supports SHA-256 and ETHASH accounts.
Let me know if it works for you!
