Teach a cost how to calculate, and it does the math every time.
Formulas turn a cost from a flat number into a rule - using quantities, entered values, and your own named inputs.
Some costs are a flat number. Most depend on the job - the square footage, the count, the linear feet. Formulas let a single cost code price a small job and a big one correctly, on its own.
Formulas, not just flat rates
A formula computes the cost from inputs and a rate, so you define the rule once and the engine applies it to whatever the job turns out to be.
Bring the quantity into the math
You decide whether a cost multiplies by quantity or already accounts for it inside the formula. That matters for add-on costs that shouldn't be multiplied twice - a one-time charge stays a one-time charge no matter how big the job is.
Name your own input
The value a cost asks for defaults to "Entered Value," but you can rename it per cost type - "Linear feet," "Number of windows," "Coats of paint." Your estimators and your customers read something that makes sense instead of a generic label.
