What it means
The idea shows up in several corners of business. Budgets tend to ratchet upwards because a department that received more money last year argues it needs at least that much next year.
Pay rises are rarely reversed, and cost bases built in good years are painful to cut in bad ones. A related use is in performance targets.
If a manager beats this year's target, the target for next year is often raised to the new level, so a strong year makes the next one harder. Staff who understand the ratchet may hold back effort or push results into later periods to avoid setting a high bar.
In venture finance, a ratchet is a term in an investment agreement that protects an investor if a later round of funding is priced lower. The most aggressive form, the full ratchet, resets the investor's conversion price to the new, lower price, which hands the investor extra shares.
A milder version, the weighted-average adjustment, softens the reset by taking account of how many new shares are issued. Ratchets also appear in consumer behaviour and macroeconomics.
Households that have grown used to a higher standard of living are slow to cut spending when income falls, so consumption does not fall as fast as income. This helps explain why spending can stay higher than income for a while.
The nuance is that a ratchet is not always bad. It can protect an investor or reward sustained performance, but it can also entrench waste or discourage effort.
The question to ask is who benefits from the one-way movement and who bears the cost. Companies can design around the effect if they notice it early.
Resetting budgets from zero, setting multi-year targets and paying bonuses on improvement over a long-run average all weaken the one-way pull. Without such design, the natural drift is always upward.
In practice
Real-world examples.
Example
A government department is given a 5% budget increase after a successful project. The following year the department treats the new level as its baseline, even though the project has ended. Spending stays high while the original purpose has gone.
Example
A sales director beats her target by 20% and is rewarded with a bonus. The next year, the target is raised by 20% to match, and the new target proves too hard to reach. She learns to hold back some sales to avoid setting an impossible bar.
Example
A start-up founder negotiating a funding round is offered a term sheet with a full ratchet. She realises that a down round later would give the investor a large share of the company. She negotiates a weighted-average adjustment instead.
Formula
Calculation
Full ratchet: new conversion price = price of the new down round; shares received = amount invested / new conversion price
An investor puts $2,000,000 into a start-up at $2.00 per share and receives 2,000,000 / 2.00 = 1,000,000 shares. The company later raises money at $1.00 per share, and the full ratchet resets the investor's price to $1.00. The investor is now entitled to 2,000,000 / 1.00 = 2,000,000 shares, an extra 1,000,000 shares at no additional cost, which dilutes the founders.Case study
Seen in the real world.
Brightline Robotics is an illustrative, fictional start-up that raised $3,000,000 from an investor at $3.00 per share, which gave the investor 1,000,000 shares. The investor insisted on a full ratchet to protect its position.
Eighteen months later, a slower market forced the company to raise new money at $1.50 per share. The ratchet reset the investor's price to $1.50, which increased its holding to 3,000,000 / 1.50 = 2,000,000 shares, an additional 1,000,000 shares for no extra cash.
The founders found their ownership cut sharply and spent months renegotiating with the investor. Had the company negotiated a weighted-average adjustment instead, the investor's extra shares would have been much smaller. The illustrative lesson is that a ratchet clause can turn a modest price fall into a large loss of control, so its terms should be tested against a downside scenario before signing.
Watch out
Common mistakes.
- Assuming last year's budget or target is a neutral starting point, when it often locks in a higher baseline.
- Agreeing to a full ratchet in a funding deal without modelling what a down round would do to ownership.
- Treating the ratchet effect as only a negative, when it can also reward performance or protect an investor.
Questions
People also ask.
What is the difference between a full ratchet and a weighted-average adjustment?
A full ratchet resets the price to the lowest new price regardless of size, whereas a weighted-average adjustment softens the reset by taking account of how many new shares are issued.
How can a manager avoid the budget ratchet?
Use zero-based budgeting, where every cost must be justified afresh each year, or set targets with a rolling baseline.
Does the ratchet effect appear in the economy as a whole?
Yes, economists use it to describe prices, wages or spending that rise easily but fall slowly.
