Bake in and factor in are easy to blend because both describe accounting for something -- but they describe two different moments in that process.
"Factor in" (or "account for") means considering a variable when computing a number or making a judgment call. It's a one-time mental or analytical step. "Bake in" means the result of that consideration is now a fixed part of the plan, price, or system going forward -- not just something you thought about once, but something now built into the structure.
A calculation vs. a structural result
Factor in (one-time calculation): "We factored in currency risk when we priced the deal."
Bake in (ongoing structural feature): "We baked a currency buffer into the contract, so future exchange-rate swings don't require renegotiation."
The first sentence describes a step in the pricing process. The second describes a term that now permanently exists in the contract because of that step. A team can factor something in without ever baking anything in -- the calculation happens, but nothing structural changes as a result.

Because "bake in" frequently describes the outcome of a "factor in" step, the two words show up together naturally: you factor in a risk, and the result gets baked into the model. Confusing them the other way -- claiming something is "baked in" when it was really just considered once and left out of the final structure -- overstates how permanent the decision actually is.
The rule
Use "factor in" when describing the act of considering something in a calculation or decision. Use "bake in" when describing the fact that the outcome of that consideration is now a fixed, embedded part of the plan, price, or system. If nothing structural changed as a result of the consideration, "factor in" is the accurate word -- not "bake in."
Practice scenarios
Practice choosing between bake in and factor in in situations like:
- describing a one-time pricing calculation versus a permanent contract term
- explaining what changed structurally in a forecast after a risk review
- writing a status update that distinguishes "we considered this" from "this is now built in"
Useful practice phrases:
- "We factored in currency risk when we priced the deal."
- "We baked a currency buffer into the contract."
- "That's factored into this quarter's number, but it isn't baked into the model going forward."
Factor in is the calculation. Bake in is what happens to the plan afterward, if anything does.
