Freelance Retainer Calculator
Structure predictable, high-value monthly retainers for freelancers, consultants, and agencies. Calculate discounted capacity, overage surge rates, and annual recurring income.
Retainer Capacity & Billing Rules
Configure reserved client hours, discount incentives, and contract term.
Transitioning from Hourly Churn to Predictable Retainer Revenue
Trading hours for dollars creates feast-and-famine cycles for independent professionals, consultants, and creative agencies. Retainers exchange a modest capacity commitment discount for guaranteed monthly recurring revenue (MRR) and priority client access. This tool calculates fair monthly retainer retainage, buffer limits, rollover policies, and surge overage rates.

Frequently Asked Questions
What is a retainer fee agreement?
A retainer is an advance payment made by a client to secure a designated amount of a professional's time, expertise, or priority availability over an agreed billing cycle (usually monthly).
Should freelance retainers include rollover hours?
Generally, you should avoid allowing 100% rollover of unused hours because it creates unpredictable capacity bottlenecks in future months. The industry standard is either 'use-it-or-lose-it' or a strictly capped 20-25% rollover valid for a maximum of 30 days.
How much of a discount should I offer for a monthly retainer?
A common benchmark is 10% discount for a 3-month commitment, and 15% to 20% for a 6 to 12-month contract. Never discount below your profitable operating margin.
How do you handle out-of-scope requests or extra hours?
Specify in your retainer contract that once monthly allocated hours are reached, additional work is billed at an overage surge rate (typically 1.25x to 1.5x your standard hourly rate) with client written pre-approval.
