Three practical calculators and a follow-up checklist for contractors. Calculations stay in this page; no form data is sent or saved. Use one currency consistently.
A 25% markup is not a 25% margin. Check both before submitting your price.
Profit = price − cost. Margin = profit ÷ price. Markup = profit ÷ cost. Include overhead in cost if you want it reflected; this is not after-tax net profit.
Compare crew size, paid hours and your own labor burden assumption.
Budget = workers × hours × rate × (1 + burden ÷ 100). The example burden is not a benchmark. Overtime premiums, travel and equipment must be budgeted separately.
Price a scope change using its cost and your target margin.
Price = cost ÷ (1 − margin ÷ 100). Include labor, materials, subcontractors and overhead in cost. Tax, contract limits and customer approval are separate.
Use for an existing inquiry where follow-up is appropriate. Stop if the person declines or opts out.
Checklist selections reset when you reload. Examples are planning scenarios, not promised savings or earnings.
