Disclaimer: These figures are illustrative employer-cost estimates only and are designed for quick workforce planning.

Always sense-check significant decisions against your payroll provider or finance lead.

How Payroll Forecasting is Calculated

Each row starts with the current hourly rate and contracted weekly hours. The tool then applies your selected pay-rise method, recalculates annual salary cost, and layers employer on-costs on top so you can compare current and proposed totals like-for-like.

Annual Employer Cost = Base Pay + Employer NI + Employer Pension

Pay-rise method

Choose whether to match the NLW uplift, bring pay up to NLW, apply a custom percentage, set a known new hourly rate, or hold pay flat.

Employer NI

Employer National Insurance is applied using the current HMRC rates and thresholds, so the forecast reflects payroll on-costs rather than headline pay alone.

NHS pension

Where you tick NHS pension, the forecast adds the employer pension contribution so you can see the fuller cost impact for staff who are in the scheme.

The public version is designed for fast scenario planning and supports up to 5 staff in one run.
