Estimating Capital Expenditures

[Jacob P.]

I'm new to Bigger Pockets, and recently started playing with the investment calculator. 

Previously, I had used another online calculator which had a "maintenance" field that was pre-populated with an estimate of 10% of monthly rent. There was no field for capital expenditures. On the BP calculator, I see that there is a "capital expenditure" AND a "repairs" field. I guess I hadn't really considered saving for capital expenditures as part of the investment, but while doing some research, I see some people on the forums suggest budgeting as much as 10 percent for repairs, AND 10 percent for capital expenditure.

Obviously that 10 percent has the potential to be a big chunk of potential cash flow. I would love to hear what numbers others are plugging in for these fields.
