This calculator lets you demonstrate that a client who is employed and considering making a payment to a company pension can actually have a larger amount paid into their pension by using salary exchange.
You can explain to your client that instead of making the payment themselves, they can agree with their employer to take a reduction in their salary. The employer would then pay into the pension on their behalf.
Savings the employer makes in Employer NI.
The employee has increased net disposable income whilst payments into their pension are maintained at the current level.
