What does ratably mean?
Ratably means in accordance with a specified rate or proportion, most often when describing payments or charges divided across a period. A party may pay rent, fees, or other obligations ratably by calculating each payment from the relevant days, units, or shares rather than assigning the whole amount to one date. The term does not necessarily imply equal payments: the portions may be equal, proportional to use, or calculated according to another agreed formula. Its legal and financial character distinguishes it from the more conversational phrase "split evenly." The adverb is formed from "ratable," meaning subject to payment according to a rate. Although "ratably" can convey the same idea as "proportionately," it is especially common in contracts, leases, tax provisions, and other formal arrangements where the method of calculation matters. The alternative spelling "rateably" is also established, especially in older and statutory English.

Where does ratably come from?
The adverb "ratably" was formed from "ratable" with the suffix "-ly." The adjective "ratable" in turn derives from "rate," a word that entered Middle English from Old French and ultimately from Latin rata, the feminine ablative form of ratio, meaning "reason" or "proportion." The same Latin root also underlies words including "ratio," "ration," and "rational."
