IRC § 1401 (Self-Employment Tax

Freelance Hourly Rate Calculator (1099 Reality)

Compute the billable hourly rate a 1099 freelancer must charge to clear a target take-home — covering self-employment tax under IRC § 1401 (15.3% on the first $176,100 of net earnings, 2.9% above, plus 0.9% Additional Medicare under § 1401(b)(2)), federal + state marginal income tax, the self-employed health insurance deduction under IRC § 162(l), retirement contributions targeting Solo 401(k) / SEP IRA limits under IRC § 401(k) / § 408(k), business expenses, and the 55-70% billable-hour reality. Reverses the W-2-thinking 'salary divided by 2,080' error that under-prices freelance work by 40-60%.

Cost-plus pricing methodology (estimated hours × billable hourly rate = floor)

Freelance Project-Based Pricing Calculator

Translate a freelancer's hourly rate into a defensible project quote across three price points: minimum (cost-plus floor), target (cost-plus with risk and scope-creep buffer), and premium (value-priced uplift over cost-plus). Computes effective hourly rate at each scenario, maximum overrun the target quote can absorb before going underwater, and the project-vs-hourly breakeven (at how many actual hours hourly billing would have been more lucrative). Based on the Standish Group CHAOS and PMI Pulse of the Profession project-overrun benchmarks.

Standard retainer-pricing methodology: cost-plus floor (target monthly hours × billable hourly rate)

Freelancer Retainer Pricing Calculator

Translate a freelancer's hourly rate into a defensible monthly retainer price. Computes the cost-plus floor (target hours × hourly rate), the recommended retainer (cost-plus × (1 − retainer discount + predictability premium)), the effective hourly rate at target consumption and at the scope cap, the net discount against standard hourly billing, and the overflow billing rate above the scope cap. Industry-standard retainer-pricing methodology with the discount/premium structure that protects both freelancer and client.
