Best incentive calculator and predictor

I use Everstage to calculate my incentives, predicting the incentive based on prospects and knowing my rank in my team. I have integrated ever-stage with Salesforce, so it was easier to predict incentives as per the opportunities of sales. No competitors, as far as I know, are available in the market. No such thing as of now that I didn't like. Services provided are good as per my knowledge when comparing with other platforms. So for me its best. It will be better if they can show whole Salary pay as well and check achievement of other team members to have healthy competition.
