Three tools sit here: an acca calculator, a deposit limit planner and a note on betting duty. Each shows its formulas and a worked example on the page, so you can follow the arithmetic without the tool. Nothing you type is stored or sent, and no tool recommends a stake or a limit.

## Acca calculator

The [acca calculator](https://beforeyouinstall.com/tools/accumulator-calculator/) takes a stake in euro and 2 to 15 selections, in fractional odds (5/1) or decimal odds (6.00).

- Decimal price: d = 1 + a ÷ b, for fractional odds a/b.
- Combined odds = the product of all decimal prices.
- Return = stake × combined odds. Profit = return − stake.
- Chance of one selection = 1 ÷ d.

It leaves out void bets, dead heats, Rule 4 and bonuses.

**Worked example:** a €7.50 stake on 6/4, 11/10 and 1/2. The decimal prices are 2.50, 2.10 and 1.50.

Combined odds are 7.875. Return is €59.06 and profit €51.56. The implied chance of all three winning is 12.7%.

**In short:** multiply the prices, then multiply by the stake.

## Deposit limit planner

The [planner](https://beforeyouinstall.com/tools/deposit-limit-planner/) converts a limit and its period into daily, weekly and monthly amounts. You can compare the result with a monthly budget you type in.

- Weekly = daily × 7.
- Monthly = weekly × 52 ÷ 12.
- Share of budget = monthly limit ÷ monthly budget.

**Worked example:** a €40 weekly limit is €5.71 a day and €173.33 a month. Against a €200 monthly budget, that is 86.7%.

It does not recommend an amount. Related pages: [limits, breaks and blocks](https://beforeyouinstall.com/guides/limits/) and [responsible gambling](https://beforeyouinstall.com/responsible-gambling/).

**In short:** the planner converts; you decide the amount.

## Betting duty note

The [betting duty note](https://beforeyouinstall.com/tools/tax-on-winnings-info/) shows who pays betting duty on each type of bet. Duty is charged on operators, not on punters.

Read the current rates on the [Revenue page](https://www.revenue.ie/en/companies-and-charities/excise-and-licences/excise-duty-rates/betting-duty.aspx) before you rely on them. This site makes no statement on tax on players' winnings.

**In short:** duty rates are recorded; tax on winnings is not confirmed.
