Calculating adjusted net income for tax free childcare

Hello, I am a contractor with daily rate of GBP 545 and need some guidance on calculating adjusted net income for tax free childcare ( 15 hours funding) . My current contract expires in 4 months and its always uncertain that it will be further extended. Can i still apply for childcare as i am not sure my employment will last for a year ? Also, how can I estimate my net income as i am not sure if i am eligible for the childcare ? Do i need to calculate based on gross taxable income? In that case my gross taxable income will be above 100K ? Please suggest.
