Inflation is a weapon

If you are "tithing", you are following the Law and not Grace.
Because you can not follow all the Law, as it is required of following all the Biblical Tithes rules.
Then there are all the other elements of the law that you also must follow; feast days, sacrifices, offerings, etc..
So you can not work your way to heaven.

The Protestant "tithe" is not even a Biblical one!
Deuteronomy 14:22-24
“Set aside a tithe—a tenth of all that your fields produce each year. 23 Then go to the one place where the Lord your God has chosen to be worshiped; and there in his presence eat the tithes of your grain, wine, and olive oil, and the first-born of your cattle and sheep. Do this so that you may learn to honor the Lord your God always.
24 If the place of worship is too far from your home for you to carry there the tithe of the produce that the Lord has blessed you with, then do this: 25 Sell your produce and take the money with you to the one place of worship. 26 Spend it on whatever you want—beef, lamb, wine, beer—and there, in the presence of the Lord your God, you and your families are to eat and enjoy yourselves.

(You notice they don't teach that part! or this one!)

27 “Do not neglect the Levites who live in your towns; they have no property of their own. 28 At the end of every third year bring the tithe of all your crops and store it in your towns. 29 This food is for the Levites, since they own no property, and for the foreigners, orphans, and widows who live in your towns. They are to come and get all they need. Do this, and the Lord your God will bless you in everything you do.

Since your Pastor, is not a Levite y birth into that tribe,, he has no right to your "tithe" money, even in every third year, only foreigners, widows and orphans do..
