How to Raise Your Rates With Existing Clients (Email Templates)

Raising your rates with a client you already work with feels harder than quoting a new one. You know the people, you fear losing the account, and most advice stops at "be confident". This guide gives you a decision process instead: check your contract, pick the right moment, size the increase, give enough notice, send a clear email, and prepare for the two possible outcomes.

It applies to consultants, agencies and freelancers in any country. Where the rules depend on the law that governs your contract, the guide says so and gives examples.

Step 1: Check what your contract allows

Before you write anything, open the contract or statement of work. Your existing rate is usually a contractual term, and in most legal systems you cannot change it on your own during the term. A new rate generally needs the client's agreement, or a clause that already allows it.

• Fixed-price work in progress: the agreed price normally stands until delivery. Apply the new rate to the next project, not the current one.
• Price review or indexation clause: if your contract already says rates are reviewed each year or follow an index, follow its procedure and deadlines exactly.
• Variation clause: many B2B contracts say changes must be in writing and signed by both parties. In the UK, the Supreme Court held that such a "no oral modification" clause is effective and an oral agreement to change the contract does not override it (Rock Advertising v MWB [2018] UKSC 24, The National Archives (UK), Find Case Law, page consulted 4 November 2026). A "yes" on a call is not enough: get a signed amendment or the written form your contract requires.
• Renewal date and notice period: note when the contract renews and how much notice either side must give to end or change it. That date usually decides when your increase can start.

Rules differ by country. In the UK, consumer protection law such as the Consumer Rights Act 2015 mainly protects individuals, not businesses contracting with each other: the Act defines a consumer as an individual acting for purposes wholly or mainly outside their trade, business, craft or profession (legislation.gov.uk (UK), Consumer Rights Act 2015, section 2, page consulted 4 November 2026). In France, ending or sharply reducing an established commercial relationship without sufficient written notice can make you liable, with the required notice capped at 18 months (Légifrance (FR), Code de commerce, Article L442-1 II, page consulted 4 November 2026). In the US or India, the answer mostly depends on your contract and the law it names. If the client is large or the relationship is long, ask a local lawyer before you send the email.

Step 2: Choose the right moment

The best moment is one you announced in advance or one tied to a change the client can see. Use this table to pick your trigger.

Avoid raising rates right after a missed deadline, during a dispute, or in the middle of a delivery the client is anxious about. A satisfied client is more likely to accept a higher price (SCORE, How to Raise Prices Without Losing Customers).

Step 3: Decide how much

There is no official or universal percentage. Size the increase from your own numbers, in this order:

1. Recalculate your floor. Work out the rate you need to cover costs, non-billable time and income targets. The day rate calculator and the guide on how to calculate your consulting day rate walk you through it.
2. Compare with your current new-client rate. The gap between what old and new clients pay is your maximum case for an increase.
3. Check inflation in the currency you invoice in. Look up the latest 12-month consumer price figure from the official source, for example the US Bureau of Labor Statistics, Consumer Price Index, page consulted 4 November 2026, the UK Office for National Statistics, consumer price inflation bulletins, page consulted 4 November 2026, Eurostat for the euro area, or your national statistics office. Add up the months since your last increase.
4. Pick a number you can explain in one sentence. "In line with inflation since our last review" or "aligned with my current rate for new clients" are explanations a buyer can forward to finance.

Worked example (assumptions, not benchmarks): you bill a client 600 per day on a retainer of 4 days a month. Your floor has risen to 640 and new clients pay 700. You choose 660 per day, 10% more, from the next renewal. The client's monthly cost goes from 2,400 to 2,640. If you would also accept a lower volume, you can offer 3 days at 700 as an alternative.

If many old clients are far below your current rate, a single large jump is harder to accept than a step plan. For example, half the gap at renewal and the rest twelve months later, both announced in the same email.

Step 4: Give enough notice

Beyond what your contract or local law requires, give the client time to adjust its budget. These are practical suggestions, not legal minimums:

• Monthly retainer: announce before the next renewal or budget cycle, ideally at least one full billing cycle ahead.
• Annual contract: announce before the renewal notice deadline, so the client can still decide without pressure.
• Project-based client: announce the new rate before you send the next proposal, not inside it.
• Client with a fiscal year: ask when budgets are set and get your new rate in before that date.

Telling business clients in advance is also one of SCORE's main recommendations for service and B2B firms (SCORE).

Step 5: Send a clear email

Call it a price increase, state the new rate and the start date, and give one short reason. SCORE, citing marketing professor Utpal Dholakia in Harvard Business Review, advises against euphemisms such as "price adjustment" and against over-explaining your margins (SCORE). Replace the bracketed parts below. If your contract requires a signed amendment, attach it.

Template A: annual increase

Subject: Rates for [year or contract period]

Hi [Name],

Thank you for another year of work together on [project or retainer]. I review my rates once a year, and from [date] my rate will be [new rate] per [day/hour/month], up from [current rate]. This reflects [one reason: inflation since our last review / my current rate for new clients].

Everything else stays the same: [scope, response times, reporting]. Work already scheduled before [date] will be billed at the current rate.

I've attached the updated [rate schedule / amendment] for signature. Happy to discuss it on a call if useful.

Best regards,
[Your name]

Template B: new scope, new rate

Subject: Proposal for [new scope]

Hi [Name],

Thanks for asking me to take on [new work]. This goes beyond our current agreement, which covers [current scope].

For the extended scope, my rate will be [new rate] per [unit], starting [date]. That covers [what is included: deliverables, availability, turnaround]. If you prefer to keep the current scope only, the current terms stay as they are.

I can send an updated statement of work this week. Which option works best for you?

Best regards,
[Your name]

Template C: grandfathered client

Subject: My rates from [date], and what it means for you

Hi [Name],

From [date], my standard rate for new clients is [new rate] per [unit]. Because we have worked together since [year], your current rate of [current rate] will stay in place until [date, for example 12 months later]. From then, your rate will be [new rate or an intermediate step].

If you'd like to fix your rate for longer, I can offer [option: a longer commitment, a set number of days per month] at [rate].

Best regards,
[Your name]

Keeping existing clients at their rate for a fixed period, and telling them so, is a common approach for B2B businesses; SCORE gives a 12-month hold as an example (SCORE). Always put an end date on it, or the exception becomes permanent.

Step 6: Answer pushback

Most objections fall into a few types. Decide your answer and your walk-away point before you send the email.

Trade scope or commitment, not your rate. If you lower the rate after the first objection, the next increase will be harder.

Step 7: If the client leaves

Some clients will decline. Plan for it so the decision does not damage your reputation or your cash flow.

• Finish work in progress on the agreed terms and hand over files, access and documentation.
• Send a short, polite closing email and say you would be glad to work together again.
• Check when the last invoice is due and follow up on it.
• If you are the one ending a long relationship, give written notice as your contract and local law require. In France, see the notice rules above.
• Replace the revenue before it stops. Browsing subcontracting needs and tenders on Sendbiz is one way to fill the gap with clients who already accept your rate.

Before you raise rates, check how much of your income each client represents. If one client is a large share, a step plan or a longer notice period reduces the risk of losing it all at once.

Common mistakes

• Changing the rate on an invoice without warning. SCORE warns service businesses against slipping increases into bills (SCORE).
• Ignoring the contract. A rate change agreed on a call may not be valid if your contract requires written, signed variations.
• Apologizing or over-justifying. Long explanations about your costs invite negotiation. One reason is enough.
• Grandfathering with no end date. Old clients end up paying far below your rate for years.
• Raising rates mid-project on fixed-price work. Apply the new rate to the next project or statement of work.
• Waiting several years, then asking for one large jump. Regular reviews are easier to accept and to plan for.
• Offering secret discounts to some clients. Clients talk to each other; keep exceptions documented and time-limited.
