Online Roulette Calculators 2026

Reviewed by the CasinoOnlineReviews deskUpdated Written for readers in the United States

Roulette Calculators are online devices used by gamblers to help them manage their bankroll more efficiently. The core function of a roulette calculator is to depict the most suitable base betting unit for players based on their individual bankroll size. The betting unit remains the same throughout the gambling session.

Adequate bankroll management involves deciding how much money you are going to bet on in that specific roulette session i.e., the size of your overall bankroll for that game. That amount is then further divided into wagers per spin. Roulette Calculators help indecisive players with their bankroll, and also assists strategic players with record keeping. The calculators are available online and can be used free of charge.

How Do They Work?

Using a roulette calculator to play roulette is straightforward. Players simply enter the exact amount they’re willing to spend on that session in the specified field, then press ‘calculate’. For example, if player X set aside $500 for one roulette session, the roulette calculator will calculate and propose three different betting units for the player to choose from. These include a high-risk unit, a safe unit, and a recommended unit. Which option you choose is entirely up to you.

The Different Kinds of Betting Units

There are three different kinds of betting units available for players to choose from. Have a look at each unit and its features below.

  • High Risk Betting Units. This high-risk unit applies to the big money spenders and risk takers. Here, big bets are made, and even greater payouts are collected. However, players can also experience big losses. Its therefore advised to proceed with caution. High risk betting units make up 4% of a player’s bankroll regardless of the initial bet amount placed. The same principle applies to all other types of betting units.
  • Safe Betting Units. Safe betting units are small amounts of money played with each spin, which allows players to safeguard their bankroll and prolongs their time around the roulette table. Many online roulette casinos allow gamblers to place low stakes, while land-based casinos have minimum and maximum stake limits which might not be suitable for this kind of player. This unit makes up 1% of a player’s bankroll.
  • Recommended Betting Units. The recommended betting units makes up 2% of a player’s overall bankroll. It offers players a good balance between risk and reward, making it the suggested option. Choose wisely.

Roulette Calculators Overview

Roulette calculators are useful in helping you decide how much to bet when you are feeling uncertain, and although this is great, they cannot influence whether you win or lose. Roulette calculators can also lead to better money management. You will still need to use your own judgement and decide whether or not the betting units suggested by the calculators are worth using or not.
