Calculators
OwnerMath calculators form one connected pricing system: estimate capacity, set the baseline, choose the pricing model, price the work, audit reality, then plan cleaner revenue targets.
If you are deciding where to begin, start with Step 1. If you are lost or on the wrong page, open the Calculator Finder and recover in one click.
Step 1 of 8 (branching path)
Tool: Billable Hours Calculator
Before you set a rate or quote a project, know how many hours you can actually invoice. Admin, sales, meetings, and time off are real work — they just are not billable.
Step 2 of 8 (branching path)
Tool: Freelance Hourly Rate Calculator
Your hourly floor is the number every quote, retainer, and revenue target depends on. Include expenses, tax reserve, savings, and slow-month buffer.
Step 3 of 8 (branching path)
Tool: Freelance Pricing Calculator
If you know your baseline but not whether this should be hourly, fixed-fee, or retainer, use this to route into the right pricing model before quoting.
Step 4 of 8 (branching path)
Tool: Project Quote Calculator
Fixed-fee pricing is still hourly math underneath. Count delivery, admin, revision risk, and profit before the proposal leaves your inbox.
Step 5 of 8 (branching path)
Tool: Retainer Pricing Calculator
Ongoing monthly work needs scope, meetings, overhead, risk buffer, and margin priced on purpose — not treated as an open-ended availability promise.
Step 6 of 8 (branching path)
Tool: Effective Hourly Rate Calculator
After delivery, check whether the project held up. The invoice total is not the same as what you earned per hour once the hidden hours show up.
Step 7 of 8 (branching path)
Tool: Scope Creep Cost Calculator
When a fixed-fee project expanded, calculate the exact cost of unpaid extra hours, rate collapse, and missed change orders.
Step 8 of 8 (branching path)
Tool: Revenue Goal Calculator
