How to Use This Visa Deadline Calculator

The calculator generates a dynamic timeline based on your specific circumstances. Here is what each field does:

  1. Course Start Date: The official start date of your programme. This is the anchor for your entire timeline — all other deadlines are calculated backward from this date.
  2. University: Select your institution. Different universities have different internal deadlines for CAS requests and deposit payments, and the calculator uses the specific dates for the university you choose.
  3. Study Location: Choose “Outside London” or “Inside London.” This determines your monthly maintenance rate requirement (London rates are significantly higher).
  4. Nationality (optional): Enter your nationality if you want to check for country-specific earlier deadlines. Some universities have earlier visa deadlines for certain nationalities due to higher application volumes or enhanced security checks.
  5. Visa Processing Speed: Select your intended processing speed (Standard, Priority, or Super Priority). This calculates your latest recommended application date to ensure your visa is ready before your course starts.
  6. Accommodation Checkbox: Tick this if you have already paid for university accommodation. You may be able to deduct up to one month’s maintenance from your required funds, lowering the amount you need to show in your bank account.
  7. Available Funds & Funds Held Since: Enter your available funds and the date you first reached the required amount. The calculator checks whether you have met the 28-day funds holding rule — a critical requirement that catches many applicants off guard.

Click Calculate My Timeline, and the tool instantly generates your personalised deadlines, financial breakdown, and a document checklist.

Understanding Your Results: Timeline, Risk Score, and Deadlines

The output is designed to give you a clear, prioritised view of what needs to happen and when. Here is how to read the key sections.

The Risk Score (0–100)

At the top of your results, you will see a status badge: “On Track” (green), “At Risk” (amber), or “Urgent” (red), alongside a numerical risk score. The risk score is calculated based on how tight your timeline is. If you have already passed a critical deadline — such as the earliest visa application date or the funds holding period — your risk score will increase. A score of 0/100 means you are fully on track. A high score indicates you need to take immediate action or may need to defer your intake.

Your Timeline (Key Milestones)

The timeline lists every critical milestone in your visa journey. Here is what each one means:

  • CAS Request Deadline: The last date to request your Confirmation of Acceptance for Studies from your university. Missing this can delay your entire application.
  • Deposit Payment Deadline: The last date to pay your tuition deposit to secure your place. Your university will not issue your CAS until this is paid. Deposits typically range from £2,000 to £5,000 depending on the institution.
  • Pre-CAS Interview Deadline: Some universities require a short interview before issuing the CAS. This is the last date to complete it.
  • CAS Issuance Deadline: The latest date your university will issue your CAS. This is typically several weeks before your course starts.
  • Earliest Visa Application Date: You can apply for your visa up to 6 months before your course starts if applying from outside the UK. If this date has already passed, the tool marks it as “PASSED” — this is expected if you are applying later in the cycle, not a cause for panic.
  • Latest Recommended Visa Application: The date by which you should submit your visa application to allow enough time for processing before your course starts. Applying after this date risks not receiving your visa in time.

Why is my “Earliest Visa Application Date” marked as PASSED? You can apply for a UK student visa up to 6 months before your course start date when applying from outside the UK. If you are calculating your timeline less than 6 months before your course begins, that date will naturally be in the past. It simply means the application window is already open — you can apply immediately.

Decoding Your Financial Requirements

The financial requirements section is the most critical part of the calculator. Getting this wrong is one of the most common reasons for visa refusal. Here is what each figure means:

Field What It Means
Required Maintenance Funds The total amount you must show in your bank account to cover living costs.
Monthly Maintenance Rate The monthly rate set by UKVI. Current rates: £1,171/month outside London, £1,529/month inside London. New rates from 30 November 2026: £1,203/month outside London, £1,570/month inside London.
Months of Study The number of months of maintenance you are required to show. This is typically capped at 9 months, even if your course is longer. For a 9-month period, the total required is £10,539 outside London or £13,761 inside London at current rates, or £10,827 outside London or £14,130 inside London at the new rates (for courses starting on or after 30 November 2026).
Funds Holding Period You must hold the required funds in your account for a continuous 28-day period. The bank statement must be dated within 31 days of your visa application.
Rate Tier The UKVI maintenance rates change periodically. The tool automatically applies the correct rate tier based on your course start date (e.g., “Post-Nov 2026 (New Rates)”).

The 28-Day Rule Explained: UKVI requires that the required maintenance funds have been held in your bank account (or your parent’s/guardian’s account) for a continuous 28-day period. The end of this 28-day period must be within 31 days of the date you submit your visa application. If your funds dropped below the required amount at any point during those 28 days, the requirement is not met. Always check the official UKVI financial evidence guidance for the most up-to-date rules.

Accommodation Deduction: If you have already paid for university accommodation, you may be able to deduct up to one month’s maintenance from your required funds. The calculator automatically applies this deduction when you tick the accommodation checkbox.

Your UK Student Visa Document Checklist

The calculator generates a personalised document checklist based on your inputs. Here is what each item is and why it matters:

  • Valid Passport: Must be valid for the duration of your course. Ensure it has blank pages for the visa vignette.
  • Confirmation of Acceptance for Studies (CAS): Your university issues this unique reference number after you have met all conditions and paid your deposit. It is the most important document in your application. The CAS is an electronic document, not a physical certificate.
  • Financial Evidence (Bank Statements): Must clearly show the required funds held for 28 consecutive days. Statements must be original or certified electronic copies.
  • Academic Qualifications: Your degree certificates, transcripts, and any other qualifications listed on your CAS.
  • English Language Test Results: Your IELTS, TOEFL, or other approved English test scores (unless you are exempt or the university has confirmed your MOI).
  • ATAS Certificate (if required): Required for certain sensitive subjects at postgraduate level. Your university will tell you if you need one.
  • Tuberculosis Test Results (if required): Required for applicants from certain countries. Check the UKVI list of countries requiring a TB test to see if this applies to you.
  • Immigration Health Surcharge (IHS) Payment: A mandatory fee paid as part of your visa application. It covers your access to the NHS during your stay. The current rate for students is £776 per year of the visa granted.
  • Visa Application Fee Payment: The standard visa application fee is £558 for applications submitted from outside or inside the UK.
  • Biometrics Appointment: You must attend a visa application centre to provide your fingerprints and photograph.

Frequently Asked Questions About This Tool

How accurate is the timeline generated by this calculator?
The calculator uses university-specific deadlines where available and applies standard UKVI processing times. However, visa processing times can fluctuate based on application volumes and time of year. UKVI’s standard processing time for applications submitted from outside the UK is typically 3 weeks (15 working days). The timeline is a planning tool, not a guarantee. Always apply as early as possible within the permitted window and monitor UKVI’s official processing time updates.
Why does the calculator use a “Post-Nov 2026” rate tier?
The UK government periodically updates the maintenance rates required for student visa applications. The calculator automatically applies the correct rate tier based on your course start date. The “Post-Nov 2026 (New Rates)” tier reflects the updated maintenance rates that apply to courses starting on or after 30 November 2026. The new rates are £1,203 per month for courses outside London and £1,570 per month for courses inside London. This ensures your financial requirement calculation is accurate for your specific intake.
What happens if my Risk Score is high?
A high Risk Score means one or more of your deadlines have passed, your funds have not been held for the required 28 days, or your timeline is too tight for standard visa processing. The tool will highlight which area is causing the risk. If your score is high, you may need to consider priority visa processing, deferring your intake, or contacting your university to discuss your options. This tool is for planning — it is better to identify these issues early than to discover them at the application stage.
Can I deduct my accommodation payment from the maintenance funds?
Yes, if you have already paid for university accommodation, you may be able to deduct up to one month’s maintenance from your required funds. The calculator automatically applies this deduction when you tick the accommodation checkbox. However, the accommodation must be university-provided or university-arranged, and you must provide evidence of the payment. Private rental payments cannot be deducted.
Does this calculator save or send my personal information anywhere?
No. All calculations are performed locally in your browser. Nothing you enter — including your nationality, available funds, or university selection — is saved or sent anywhere. You can safely use the tool without privacy concerns.
Is this calculator free, and do I need to sign up?
Yes, it is completely free with no sign-up or account required. Just enter your details and your timeline updates instantly.
Disclaimer: This calculator uses standard UKVI processing times and university-specific deadlines to generate estimates. Visa processing times, maintenance rates, and university deadlines are subject to change. The risk score is an indicator for planning purposes only and does not constitute legal advice. Always verify the latest requirements on the official UKVI website and consult your university’s international student office or UKCISA before applying.
