Fee Increase Impact Calculator

Many practices go years without raising fees, while staff wages, rent and supplies keep climbing. Because most costs don't change when fees go up, even a small increase can raise profit a lot. This calculator shows the effect and how many patients you could lose before an increase stops paying off.

What this calculator does

Enter your yearly revenue from fees you set, the fee increase you're considering, your variable costs as a share of revenue and the share of patients or visits you expect to lose. It shows:

• the change in yearly profit,
• the change in yearly revenue,
• the patient loss that would cancel out the increase, and
• your new yearly revenue.

The formula in plain English

Profit now = revenue × (1 − variable cost %).

New revenue = revenue × (1 + fee increase) × (1 − patient loss).

New profit = revenue × (1 − patient loss) × (1 + fee increase − variable cost %). Variable costs fall with the patients you lose, but not with the fee.

Change in profit = new profit − profit now.

Break-even patient loss = 1 − (1 − variable %) ÷ (1 + increase − variable %).

A worked example

Dr. Carter's cash-pay and fee-for-service revenue is $600,000 a year. Variable costs are about 25% of revenue. She's considering a 5% fee increase and expects to lose about 2% of patients.

• Revenue change: about +$17,400.
• Profit change: about +$20,400.
• Break-even loss: about 6.3%. She could lose up to 6.3% of patients and still break even.

Profit rises more than revenue because the patients who leave also take their variable costs with them, while fixed costs stay the same.

Why it matters at each career stage

If you're: Practice owner

Review fees at least once a year. Compare with local practices and your own cost increases. A schedule that hasn't changed in several years is usually leaving money on the table.

If you're: Employed

If you're considering buying a practice, look at when fees were last updated. Low, outdated fees can be an opportunity for a new owner.

Making a fee increase work

Raise fees in small steps. A yearly 3%–5% review is easier than a 15% jump every few years.

Communicate clearly. A short note in the office and on statements is usually enough.

Focus on value. Patients care about access, communication and results. Good service makes increases easier to accept.

Watch the results. Track new patients, cancellations and revenue for a few months after a change.

Don't forget the schedule. Fee increases work best when the schedule is full. Filling empty time may matter more.

Why profit rises faster than revenue

Imagine a practice where every $100 of fees costs $25 in supplies, lab and card fees. Profit is $75. Raise the fee 5% to $105, and the costs stay at $25, so profit becomes $80, a 6.7% increase in profit from a 5% increase in fees. That leverage is why regular, modest fee reviews matter so much. The same leverage works in reverse: when fees stay flat while costs rise, profit shrinks faster than you might expect.

Pricing new services

When adding a new service, set its fee based on the time, staff, supplies and equipment it uses, plus a fair profit. Compare with local prices. It's much easier to start at the right price than to raise it later. Review new service fees after the first six months, once you know how long they really take.

When to be careful

If many patients are price-sensitive, if competitors charge much less, or if your schedule has a lot of open time, a fee increase may cost more patients than expected. Try higher loss percentages to see your risk.
