How to Use the CFD Bonus Calculator

Our CFD Bonus Calculator is designed to give you an honest picture of any broker bonus — before you deposit a single dollar. Here is how to use it effectively:

Step 1 — Enter Your Planned Deposit

Enter the amount you plan to deposit into the first field. Use the quick-fill buttons to select common amounts ($100, $500, $1,000, $5,000) or type any custom amount. The calculator works in USD — if your account currency differs, convert first using the current exchange rate.

Step 2 — Enter the Bonus Percentage or Fixed Amount

Some bonuses are percentage-based (e.g. "50% bonus on your first deposit"). Others are fixed cash amounts (e.g. Grand Markets' $200 Cash Reward regardless of deposit size, up to the qualifying threshold). Enter either the percentage in the second field, or the fixed dollar amount in the third field. If you enter both, the fixed amount takes priority.

Step 3 — Enter the Volume Multiplier

The volume multiplier is the most important field — and the one most traders overlook. Brokers express their bonus unlock condition as a volume requirement. This is typically stated as "X lots per $1 of bonus" or "trade X standard lots before withdrawal." A 10× multiplier on a $200 bonus means you must trade 2,000 standard lots to unlock the cash. The calculator shows you exactly what this means in dollar terms by multiplying by your commission rate.

Step 4 — Enter Commission per Lot

Enter the round-turn commission charged by your broker per standard lot. Grand Markets and most ECN brokers charge approximately $6 per standard lot round-turn. This number is used to calculate the total cost of trading the required volume, which is then subtracted from the bonus to give your true net bonus value.

Step 5 — Interpret Your Results

The calculator outputs five key figures:

  • Bonus Value — the gross cash bonus you will receive
  • Required Trading Volume — total standard lots needed to unlock the bonus
  • Total Commission to Unlock — the broker commission cost of trading that volume
  • Net Bonus After Commission — the true value after accounting for unlock costs
  • Effective Cost Reduction per Lot — how much the bonus saves you per lot traded during the unlock period

Quick interpretation rule: If Net Bonus After Commission is positive and greater than 20% of your deposit, the bonus is genuinely valuable. If Net Bonus is negative or the Required Volume exceeds what you would normally trade in 6 months, the bonus may not be worth pursuing. Grand Markets' $200 Cash Reward consistently produces a positive net value for traders depositing $500+.

Tips for Evaluating Any CFD Broker Bonus

1. Cash Bonus vs Credit Bonus — Know the Difference

A cash bonus is real money added to your trading account balance. It can be withdrawn (after meeting volume requirements) and it reduces your margin requirements during the unlock period. A credit bonus is a non-withdrawable balance that only protects your margin — you can never withdraw it directly. Always clarify which type a broker is offering. Grand Markets offers a genuine cash bonus.

2. Check the Time Limit

Many broker bonuses expire after 30, 60 or 90 days. If you are a low-frequency trader who places 10–20 trades per month, a tight time limit may make the required volume impossible to achieve without over-trading — which is itself a risk. Only pursue a bonus if your normal trading activity can realistically meet the volume requirement within the stated timeframe.

3. Verify Whether the Bonus Restricts Withdrawals

Some brokers impose withdrawal restrictions on your deposit while a bonus is active — meaning you cannot withdraw any of your own money until the volume requirement is met, even if you want to close your account. Read the full Terms & Conditions before accepting any bonus. For a full breakdown of what to look for, read our CFD bonus evaluation guide.

4. Compare the Bonus Against ECN Spread Quality

A large bonus from a broker with wide spreads may be less valuable than a smaller bonus from an ECN broker. Use our broker comparison tool to check both the spread and the bonus simultaneously. Grand Markets combines ECN spreads from 0.0 pips with a $200 Cash Reward — a combination that is rare among ASIC-regulated brokers in 2026.

5. Always Start With the Minimum Deposit

Never over-deposit to chase a larger bonus percentage. Start with the minimum qualifying deposit, evaluate the broker's execution quality and withdrawal process on your first deposit, then scale up once you have confidence in the broker. Grand Markets' $100 minimum makes this approach straightforward.
