Raise your rate on new work first, then give existing clients notice at a natural boundary. The fear that everyone will leave is the biggest thing standing in the way, and it's mostly wrong: a client who already works with you is far likelier to stay than to start over with somebody new.
Set the new rate on your next new client, and move existing clients at their next natural boundary.
Starting over costs your client more than the increase does, so staying is usually their easiest choice.
Write down your new rate today and use it on the very next proposal you send.
Clients are not dying to say no to you.

Most of them won't leave, and the reason is that staying is easier for them than starting over. I teach this as commitment bias: once somebody has invested time in an arrangement, they tend to stick with it. Your contact found you, made the case internally, got the budget approved, and learned how you work. Starting again means losing all of that and doing it a second time with a stranger.
Samuelson and Zeckhauser measured the same pull in 1988 and named it status quo bias. Their headline finding, in their words, is that "decision makers exhibit a significant status quo bias," sticking with the existing option more often than a rational model predicts. Their field data showed the same thing outside the lab: people already enrolled in a health plan kept choosing it far more often than new enrollees chose it fresh.
What that means for you, in order:
Raise it to the number the work is worth now, and stop trying to find a percentage that feels defensible. Consultants ask for a safe increment because a percentage feels like it needs less justification than a number. It doesn't, and small increments are how a rate stays behind for a decade.
A way through it:
Step four is the one that gets skipped. In my curriculum I ask people to write the number they want, and most write a smaller one, then admit the first number they thought of was higher. Go back to that first number. It's your client's job to negotiate, and it was never yours to do it for them.
No. Move new clients immediately and existing clients at their next natural boundary, which spreads the change out and keeps any single conversation from carrying the whole decision.
A sequence that works:
Two things this protects. Your income doesn't depend on every client agreeing at once, and you get evidence early: by the time you reach the hardest conversation, you'll have signed somebody at the new rate, which changes how you carry yourself in it. The timing of that conversation with a long-time client has its own answer.
The value of the outcome justifies it, and nothing about your calendar does. This is the part that trips up smart women: they look for a change in their inputs to point at, and inputs were never what the client was buying.
A justification. You don't have to explain your number through your costs, your margin, or how you priced it last year. State it and move on. If you find yourself building a case for the increase, that case is for you, and the internal work is a different subject from the number itself.
Here's what I see over and over. A woman has charged the same number for four years. Her work has gotten sharper, her clients get better results, and the number sits exactly where she set it in her first month of business, when she had no idea what any of this was worth.
She hasn't decided to keep that rate. She's just never decided to change it. Those feel identical from the inside and they're not the same thing at all, because one of them is yours and the other one is drift.
The fear underneath it is always the same: if I ask for more, they'll leave. And the thing is, I understand it. You built these relationships. Some of these people took a chance on you.
But look at what your client would have to do to replace you. Find someone, vet them, sell them internally, get the budget re-approved, explain the whole history again, and hope the new person is as good. Against all of that, your increase is the cheap option. Most of the time they say fine, and you spend three weeks dreading a conversation that takes ninety seconds.
Once a year, on a date you pick, whether or not anything feels wrong. A scheduled review turns pricing into a normal business decision and stops it from being an emotional event you avoid. Most consultants who feel badly behind got there by waiting for a trigger, and the trigger never arrives on its own.
You can, as a deliberate choice with an end date, and it's worth being honest about what it costs. A permanent exception means your longest relationships fund your lowest margins, and those clients usually take the most care. If you grandfather someone, decide when it ends and tell them then.
Look at what happened before you conclude the number was wrong. A rate increase delivered as an apology, without notice, or in the middle of a project reads as a change of terms. The same number at a renewal, said plainly and early, lands differently. The delivery fails far more often than the figure does.
Give context if it helps, and skip the case-building. One line about the value the work delivers is plenty. A long explanation invites your client to evaluate your reasoning, and the reasoning was never the thing they were deciding on.
