The cost of living in Estonia is relatively affordable, especially when compared to other Western European countries. Prices for food and accommodation are relatively low, and public transportation is also reasonably priced. However, some things can be quite expensive in Estonia, such as alcohol and cigarettes.
Many Estonians hardly ever use cash anymore and much of the banking is done online. You can pay with debit or credit cards in most places, even at kiosks and on trains.
Take a look at the EURES Portal to get an idea of the average of the various prices in Estonia.
