  • Typical project fee
  • Projects in the year — entered in projects

Retainer vs project fee formula

Annual retainer = monthly retainer × months. Annual project fees = project fee × projects. Keep the larger total.

  • SBA tells you to compare how you price work with the revenue those jobs bring in. This page uses one retainer and one typical project fee.
  • Unused retainer hours, change orders, and late invoices stay out unless you fold them into the amounts you type.

Practical guide

Retainer vs project fee example and edge cases

A retainer is a monthly fee. A project fee is a price for one job. Put a year of each on the same page and keep the larger total. SBA tells you to compare how you price work with the revenue those jobs bring in.

Example: Four thousand a month against five projects

The retainer is 4,000 a month for 12 months. That is 48,000. Typical projects bill 8,000. You expect five of those in the year, which is 40,000.

Example results use the default display profile. The calculator above follows your selected country and units.

How to read the result

  • Read which path is larger, then the two annual totals. A small gap can flip when you add one more project.
  • The monthly project equivalent tells you the retainer that matches that pipeline.

Edge cases worth checking

The retainer includes unused hours

If clients leave hours on the table, the retainer still bills. Lower the project count only if those unused hours would have been extra projects.

Projects slip into next year

Count only the jobs you expect to invoice in these months. A signed project that bills in January belongs in next year’s total.

What changes the result most

Monthly retainer

Use a current amount for monthly retainer. Include fees or recurring costs that belong in the same figure.

Retainer months

Keep retainer months on the same time basis as the other inputs. Monthly and annual values are easy to mix up.

Typical project fee

Use a current amount for typical project fee. Include fees or recurring costs that belong in the same figure.

Common mistakes

Check monthly retainer

SBA tells you to compare how you price work with the revenue those jobs bring in. This page uses one retainer and one typical project fee. Make sure this matches the number you enter.

Keep projects in the year consistent

Unused retainer hours, change orders, and late invoices stay out unless you fold them into the amounts you type. Use the same units and time period throughout the calculation.

Do not rely on one retainer vs project fee scenario

Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
