The client wants more. Charge the difference.

Common questions

What should I charge when a client wants to extend an image license?

Charge the difference between the usage-rights price of the new scope and the usage-rights price of the scope the client already paid for. On a $1,200 creative fee, a 6-month national web-only non-exclusive license prices its rights at $525.00. Extending it to 12 months prices rights at $742.46, so the extension fee is $217.46, not a second $525.00. Term grows with the square root of months, so each added month costs less than the ones before.

Should I credit what the client already paid?

Usually yes, in full, if the original term is still running and the client is adding to it. If the first term already ended and the client wants to keep using the images without a gap, lower the credit percentage: they have already had the use they paid for, so a smaller share of the old fee is credited against the new term.

What if the client asks to add paid ads or worldwide use?

Widening the scope raises the multipliers, and the fee is again the new rights price minus the credit. A web-only national license widened to web plus paid social, worldwide, prices rights at $1,041.60 against $525.00 already paid: an extension fee of $516.60 on the same $1,200 creative fee. Paid advertising and wider territory are worth more to the client, and they stop you licensing the same reach to someone else.

Does the rush premium apply to extensions?

Only to the new rights price, if you choose to charge it. The credit is for the original rights, which were priced without it.

Is this a contract?

No. It is a quote worksheet. Put the specific images, permitted uses, new term dates, credit and payment in a written agreement.

Pricing the original job from scratch? The licensing quote calculator uses the same formula, so the two always agree. See also how much more a national or worldwide license costs.
