Ideal price 50,000. If you open with 60,000 anchor vs 45,000 anchor (50% anchor effect), final often settles 10-20% toward anchor. High anchors pull outcomes up; low anchors pull down. Used in salary negotiation, real estate, car sales.

A worked example

Try the defaults: your ideal price of 50,000, opening anchor of 60,000, anchor strength of 50%. The tool returns 55,000.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Your Ideal Price, Opening Anchor, and Anchor Strength. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

The formula behind this

Linear anchor effect. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Why the behavioural angle matters

Most personal finance mistakes are behavioural, not mathematical. You know the math; the hard part is acting on it consistently. Calculators like this one are useful because they externalise a private feeling into a public number — and public numbers are easier to argue with than vague feelings.

What this doesn't capture

Behaviour-adjacent math is always an approximation. Human habits are lumpy and context-dependent; the figure here assumes steady behaviour which is a simplification. Treat the output as a prompt for thinking rather than a precise prediction.

What to calculate alongside this

One figure by itself is fragile. The salary negotiation calculator, the abundance mindset value calculator, and the advertising influence calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.

Example Scenario

Anchoring bias produces an expected outcome based on the inputs provided.

Frequently Asked Questions

First move best?
Mostly yes. Research shows first-mover advantage in negotiations. Anchor with informed high/low.
Weakens with info?
Yes. Well-informed counterparty less anchor-susceptible. Still effective vs uninformed.
Extreme anchor?
Too extreme = rejected as unreasonable. Ideal anchor ~15-20% from your target — enough to pull, not dismiss.
Defence?
Have your own number ready. Ignore their anchor. Research BATNA (alternative).
