A quick guide to picking the right student loan plan for planning estimates (Plan 1/2/4/5 or Postgraduate). If you choose the wrong plan, your repayment estimate can be off.
Student loan plans have different rules. If you select the wrong plan (or miss a Postgraduate loan), the calculator will estimate repayments using the wrong model. This page focuses on the safest workflow: confirm first, estimate second.
Check your Student Loans Company account, correspondence, or any payroll documentation that references your plan. If you cannot confirm quickly, treat any estimate as highly uncertain and avoid making decisions based on it.
Return to the calculator, enable student loan, pick your confirmed plan (Plan 1/2/4/5 or Postgraduate), and compare results with student loan on vs off so you understand the impact on cash planning.
Not tax advice. This guide is about reducing input errors, not determining your legal liability.
