Freelance Retainer Calculator

How retainers work

A retainer is a recurring payment for reserved capacity and priority availability. It is not simply a discounted package of hours. The client is paying for access to capacity whether or not every reserved unit is used.

Retainer vs hourly billing

Hourly billing charges for time after it is used. Retainers reserve time in advance, which can reduce scheduling risk for both freelancer and client. If you need a base rate first, start with the Freelance Hourly Rate Calculator.

Availability premium

The availability premium represents the value of keeping capacity open for the client. It is especially important when a retainer limits your ability to accept other work.

Should retainers include discounts?

Some retainers include a discount because the client commits to recurring work. Others include no discount because the freelancer is selling priority access. Make the assumption visible in the discount field.

If you are setting a consulting-style floor before adding premium or discount assumptions, compare the result with the Consulting Rate Calculator.

Unused hours and rollover policies

This calculator shows the cost of one unused reserved hour or day. It does not assume rollover. Rollover rules should be written clearly in the agreement.

For completed retainer work, the Project Profitability Calculator can help compare retained revenue with actual labor and expenses.

Example

At $100/hour for 20 reserved hours, the base value is $2,000. A 10% premium adds $200, and a 5% discount on the pre-discount value creates a $2,090 monthly retainer.

Monthly retainer formula

Base capacity value = hourly rate × reserved hours, or day rate × reserved days. Monthly retainer = base capacity value × (1 + premium % / 100) × (1 - discount % / 100). The discount applies after the availability premium.

Effective unit rate = monthly retainer / reserved capacity. Minimum contract value = monthly retainer × commitment months. Annualized value = monthly retainer × 12; it is a projection, not guaranteed income beyond the commitment.

Do the premium and discount cancel each other?

No. A 10% premium followed by a 10% discount gives 1.10 × 0.90 = 0.99 times the base price. Compare scenarios to see how each assumption changes monthly revenue.

What happens if the client uses fewer hours?

The monthly fee stays the same in this model. The unused-unit figure allocates the fee across reserved capacity; it is not an automatic refund. Specify scope, response times, overage rates, cancellation and rollover limits in the agreement.

If you collect the retainer through a marketplace or payment provider, use the Platform Fee Calculator to allow for deductions before checking profitability.

FAQ

Should unused hours roll over?

That is a business decision. Rollover can make a retainer feel safer for clients, but unlimited rollover can destroy capacity planning.

Can I price a retainer by day?

Yes. Use daily mode when the agreement reserves whole days instead of individual hours.

How does this connect to project work?

Use the Project Profitability Calculator after delivery to see whether retainer work stayed profitable.
