18 But if he consecrates his field after the yovel, then the cohen is to calculate the price according to the years remaining till the next yovel, with a corresponding reduction from your valuation.

Leviticus 27:18 Meaning and Commentary

Leviticus 27:18

But if he sanctify his field after the jubilee
Some years after it, more or fewer, or it may be, when half way towards another jubilee, or nearer:

then the priest shall reckon unto him the money according to the years
that remain, even unto the year of the jubilee;
thus, for instance, if it only required an homer of barley to sow it, and the whole value of it from jubilee to jubilee was but fifty shekels of silver; then supposing it to be sanctified in the middle of the fifty years, or at twenty five years' end, it was to be reckoned at twenty five shekels, and sold for that money, and so in proportion, reckoning a shekel for a year:

and it shall be abated from thy estimation;
not the year of jubilee, but a shekel for every year was to be deducted from the original value of fifty shekels, according to the number of years that had passed or were to come.

Leviticus 27:18 In-Context

16 "'If a person consecrates to ADONAI part of a field belonging to his tribe's possession, you are to value it according to its production, with five bushels of barley being valued at fifty shekels of silver [one-and-a-quarter pounds].

17 If he consecrates his field during the year of yovel, this valuation will stand.

18 But if he consecrates his field after the yovel, then the cohen is to calculate the price according to the years remaining till the next yovel, with a corresponding reduction from your valuation.

19 If the one consecrating the field wishes to redeem it, he must add one-fifth to your valuation, and the field will be set aside to revert to him.

20 If the seller does not wish to redeem the field, or if [the treasurer for the cohanim] has already sold the field to someone else, it can no longer be redeemed.
