Compound

Compound is a set of staking calculators plus a cloud bankroll tracker. It does not choose selections — you bring those — it does the money management around them: how much to stake, how to spread a stake, and how a plan is likely to perform over time.

Everything works from a fixed bankroll and is designed so you always know your exact exposure before you commit.

• Place Compounder — reinvests one stake across a run of selections to show the compounding effect.
• Extraction Runs — extracts a steadily growing profit across a run of winners; single or overlapping runs, with an "Economies" option for a faster build.
• Dutch — splits one stake across several runners so any winner returns about the same.
• Qualifier — screens a favourite against a structured checklist and recommends a variation.

Have your bankroll figure, your selections, and their current decimal odds ready. Decide in advance how much of the bankroll a single plan is allowed to use. Enter odds as decimals (e.g. 2.50).

Across all of Compound the real risk dial is the same: how much of your bankroll goes on each bet — as a flat stake or a fraction of the bank. Bigger stakes grow faster but bust faster; smaller stakes are slower but far more survivable.

The calculators differ only in how they spread or compound that stake — Place Compounder compounds it, Extraction Runs draws profit from it, Dutch splits it across runners — but the size you choose is what decides your risk.

To pressure-test a stake size, use the separate Bankroll Variance tool: it shows how long a losing run is normal at your odds and exactly how much capital survives it, before you risk a cent.

• Place Compounder — short-priced legs (about $1.3–$2). Every leg must win, so keep prices low and runs to roughly 3–5 legs.
• Qualifier & favourite classifier — built for hot favourites, typically win prices around $1.8–$2.5.
• Dutch — a few mid-range runners whose combined book comes in under 100%; that’s the only way it profits.
• Extraction Runs — moderate odds across a run of winners; even-money to about $3 keeps the spread smooth.

1. 1Open Place Compounder.
2. 2Enter your starting stake.
3. 3Add each selection’s decimal dividend, in running order.
4. 4Read the running balance after each leg, then the final balance, profit and ROI.
5. 5Use it to decide whether a multi-leg plan’s reward justifies the all-or-nothing risk.

Stake $15.00 · dividends 1.6, 1.9, 1.7, 1.8, 1.9
Running balance: $24.00 → $45.60 → $77.52 → $139.54 → $265.12
Final $265.12 · profit $250.12

"Single Run" mode banks each profit extraction as it comes; "Overlapping Runs" reinvests it for a larger final sweep. "Economies" lets you skip the first extraction or two to build value faster.

1. 1Choose Extraction Runs and pick Single Run or Overlapping Runs.
2. 2Set the run length and the stake per unit.
3. 3Enter the odds for each race in the run.
4. 4Optionally skip one or two early extractions (Economies).
5. 5Read the profit extracted each race and the total.

Even-money winners → extracts $2, $4, $8, $16, $32  (total $62)
Odds 1.8 / 1.5 / 1.2 / 2.0 / 2.5 → $1.80, $2.70, $3.24, $6.48, $16.20  (total $30.42)
Same odds in overlapping mode → total $142.92

1. 1Open the Dutch calculator.
2. 2Enter each runner’s decimal odds.
3. 3Enter either a total stake to split, or the return you want from any winner.
4. 4Read each runner’s stake, the total outlay, and the profit if any of them wins.
5. 5Check the book indicator — if it isn’t under 100%, Dutching can’t profit.

Split $10 across 6.00 / 6.00 / 4.00 → $2.86 / $2.86 / $4.29; any winner ≈ $17.14 (profit $7.14)
Target $100 across 4.00 / 10.00 / 5.00 → $25 / $10 / $20; outlay $55 (profit $45)

The Qualifier scores a favourite against a structured checklist (field size, barrier, time since last run, distance change, track condition, last-start result and jockey), classifies how strong the favourite is, and recommends a variation — or tells you to skip.

• A very strong favourite that clears the stricter checklist → the top variation.
• A solid favourite that clears the standard checklist → the standard variation.
• A favourite that misses an item → a more cautious variation.
• An ordinary favourite, or an unsafe track → skip / abandon.

Sign in and open the Bankroll tracker to record real results. Your balance is rebuilt from the full history and synced to your account, so it survives a lost phone or a cleared browser. Undo is exact — it reverses, never erases.

Does Compound pick horses for me?

No. You provide the selections and odds; Compound handles the money management only.

Why is my Place Compounder total so high?

Each leg reinvests the previous return, so it compounds quickly — but every leg has to win.

What odds format do I use?

Decimal odds throughout (e.g. 2.50).

A staking plan changes how much you stake, not whether a bet wins, and nothing removes the house edge. These tools are educational calculators — they do not place bets, take money, or give tips.
