Also known as:Commission Calculator, Cashback Calculator, Rebate Estimator
What is Rebate Calculator?
A rebate calculator is an interactive tool on an affiliate or IB website that lets a trader estimate the cashback they would earn from their trading activity. The trader enters expected volume — usually in lots — and the tool returns an estimated rebate figure per day, month, or year.
Under the hood it multiplies projected volume by a per-lot rebate rate, which the IB sets from the slice of spread or commission the broker shares with them. Because rebate rates differ by instrument, a well-built calculator uses different rates for major FX pairs, metals, indices, and crypto rather than one flat number.
Key takeaways
Cashback is paid per lot traded — independent of whether trades win or lose.
Rebate rates differ by instrument; a flat-rate calculator misleads.
The tool converts because it makes commission personal and concrete.
Always cap displayed estimates at what the broker actually pays.
Pair the result with a register-under-my-link CTA to capture intent.
For example, if an IB passes back $3 per standard lot on EUR/USD and a trader enters 50 lots per month, the calculator shows an estimated $150 monthly rebate — $1,800 a year — money returned regardless of whether individual trades win or lose. That framing is exactly why the tool converts: it makes an abstract commission structure feel concrete and personal.
The calculator is both a marketing magnet and a transparency device. Done honestly, it sets accurate expectations; done carelessly, it over-promises and breeds disputes when the real payout is lower.
How it works
The trader inputs projected volume and, ideally, selects an instrument. The tool multiplies that volume by the per-lot rebate rate you receive from the broker and displays an estimated cashback figure. The rate itself comes from the broker's IB agreement — a share of the spread or commission on each round-turn lot.
Because a rebate is paid per lot traded, not per winning trade, the calculator quantifies a volume-based reward that is independent of the trader's profit or loss. The best implementations pull live rate cards so the displayed estimate never drifts above what the broker actually pays.
1
Get your rate card
Obtain the per-lot rebate the broker pays you for each instrument class — FX majors, metals, indices, crypto — from your IB agreement.
2
Build the input fields
Let the trader enter monthly volume in lots and select an instrument, so the estimate reflects the correct rate rather than a flat average.
3
Apply the calculation
Multiply volume by the matching per-lot rate and present the result per month and per year for impact.
4
Add a clear disclaimer
State that figures are estimates based on entered volume and actual rebates depend on real executed trades and broker terms.
5
Route to your link
Place a register-under-my-link call to action beside the result so a convinced trader converts immediately.
Why it matters for partnership: A rebate calculator is a high-intent lead magnet: by showing a trader their personal cashback in dollars, it gives high-volume traders a concrete reason to register under your link and route their volume to you.
A cashback affiliate promoting an IC Markets Raw Spread account embeds a calculator using its real $3.50-per-lot pass-back on EUR/USD. A prospective scalper enters 80 lots per month, sees an estimated $280 monthly ($3,360 annually) in cashback, and registers under the affiliate's link to capture it — volume the affiliate then earns on for the account's lifetime.
Pro Tip
Feed your calculator from a live per-instrument rate card so a displayed estimate can never exceed what the broker actually pays you to pass back.
Common Pitfalls
An outdated calculator that promises higher rebates than the broker pays produces angry clients chasing 'missing' funds and damages your credibility.
FAQ
How is a forex rebate actually calculated?
It is your per-lot rate multiplied by the trader's traded volume in lots. Rates are quoted per round-turn (open plus close) standard lot and vary by instrument.
Is the rebate paid even on losing trades?
Yes. Rebates are volume-based, so they accrue on every executed lot regardless of whether that trade is profitable. This is a cost rebate, not a profit share.
Why do calculators show different rates for different pairs?
Brokers share different spread or commission amounts by instrument, so majors, exotics, metals, and indices carry different per-lot pass-backs. A single flat rate would misstate the estimate.
Are calculator figures a guarantee of earnings?
No. They are estimates based on the volume the trader enters. Actual rebates depend on real executed trades, instrument mix, and the broker's current terms.
Can I set my own rebate rate as an IB?
You can choose how much of your commission to pass back to traders versus keep, within the total the broker pays you. Passing more back attracts volume but lowers your per-lot margin.
Does offering rebates comply with broker rules?
Most brokers permit IB cashback, but some restrict it and some regulators scrutinise inducements. Confirm your specific IB agreement and local rules before advertising rebate figures.
