Diego consults part time and has a young child at home the other two days. He wants €1,200 a month for himself. He is in his first year, so he is on the tarifa plana: €88.56 a month to social security instead of the full quota.

He invoices €19,822 over the year and has 536 billable hours to do it in.

His rate: €37.02 per billed hour.

Two things worth noticing. He wants a bit over half of what Marta wants, but his rate is not far below hers: social security and the unbillable hours do not shrink with the working week the way the invoices do. And the rate above is a first year rate. When the tarifa plana runs out, the quota goes up and the same take-home needs a higher rate, so it is worth running the year after now rather than finding out in January.
