Bond cost basis for addons

This cost basis calculates an addon based on the sum of the estimate total and the actual bond amount. You can use a bond addon to factor in the cost of bond guarantees or step rates.

Using the standard industry method, Sage Estimating calculates the bond amount from the estimate totals.

Calculation:	1. Bond % x Estimate total = Bond amount
	2. Bond amount + Estimate total = New total
	3. Bond % x New total = New bond amount
	4. Steps 2 and 3 repeat until the bond amount stays the same
