How to Calculate Forex Cashback: Per-Lot, Pip and Commission-Share Rebates
Admin · 1 October 2026
Rebate offers are quoted in different ways — dollars per lot, pips per lot, or a percentage of commission. To compare them you need to turn each one into the same unit: dollars per standard lot. Then multiply by your volume.
Step 1: Know your volume in standard lots
One standard lot is 100,000 units of the base currency. Platforms often show smaller sizes:
| Size | Lots |
|---|---|
| Standard | 1.00 |
| Mini | 0.10 |
| Micro | 0.01 |
Add up the lot size of every trade you closed in a month. Most rebate programs count round turns (open + close) as one trade; check the broker page if you are unsure.
Step 2: Convert the rebate into dollars per lot
Per-lot rebates
These are already in the right unit. "$4.80 per lot" means $4.80 for every standard lot.
Per-pip rebates
Multiply the pips by the pip value of one standard lot. For pairs quoted in USD (EURUSD, GBPUSD, AUDUSD), one pip on one standard lot is worth about $10.
0.4 pip × $10 = $4.00 per lot
For pairs where USD is not the quote currency, the pip value moves with the exchange rate, so the dollar rebate changes slightly.
Percentage-of-commission rebates
Multiply the commission per lot by the percentage. If a Raw account charges $7 per round-turn lot and the rebate is 30%:
$7 × 30% = $2.10 per lot
Commission-share rebates are common on raw-spread or ECN accounts, where most of the broker's revenue is the commission.
Step 3: Multiply by your volume
Monthly cashback = lots per month × dollars per lot
| Lots / month | $2.10 / lot | $4.00 / lot | $6.00 / lot |
|---|---|---|---|
| 10 | $21 | $40 | $60 |
| 50 | $105 | $200 | $300 |
| 150 | $315 | $600 | $900 |
| 500 | $1,050 | $2,000 | $3,000 |
These are illustrations of the arithmetic, not promises: what you earn depends on the broker, account type and instruments you actually trade.
Step 4: Compare the net cost, not just the rebate
A bigger rebate is not automatically a better deal. Compare net cost per lot:
Net cost = spread cost + commission − rebate
A Standard account with a wide spread and a large rebate can still cost more than a Raw account with a tight spread and a smaller rebate. Our broker pages list the spread, commission and rebate for each account type so you can do this check quickly — or open two brokers in compare.
Instruments other than FX
Gold, indices and oil often pay a different rebate from currency pairs, and the lot size is defined differently (for example, 1 lot of XAUUSD is usually 100 ounces). Look for a "rebate by instrument" table on the broker page. See rebates for gold traders for more.
Skip the arithmetic
Our rebate calculator does steps 3 and 4 for a blended rate: set your monthly lots and read the estimate. For an exact figure, use the rate on the specific broker and account type you plan to open.
