Combining Income and Savings: The Formula

Updated 27 March 202610 min read

What you need to know

You can combine employment income with cash savings to meet the UK visa financial requirement. The formula multiplies your income shortfall by 2.5 and adds £16,000. Savings must be held for at least 6 months. This guide walks you through the calculation, eligible savings types, and how to avoid common mistakes.

When Do You Need to Combine Income and Savings?

The UK's family visa financial requirement sets a minimum income threshold that the sponsoring partner must meet. As of 2026, this threshold is being phased up from £18,600 to £29,000 and eventually to £38,700, depending on which transitional arrangements apply to your application.

If your employment income alone does not reach the relevant threshold, you have the option to combine your income with cash savings. This is sometimes called the "savings top-up" route. It allows applicants who earn slightly below the threshold to still qualify, provided they have enough money set aside.

This approach is particularly useful for sponsors who work part-time, who have recently started a new job at a higher salary, or whose income fluctuates. Rather than relying entirely on savings (which requires a much larger sum), you use your income as the foundation and only top up the gap.

The Formula Explained

The Home Office uses a specific formula to calculate how much savings you need if your income falls short. According to Appendix FM Section 1.7 on GOV.UK, the formula is:

Savings required = (Annual income shortfall x 2.5) + £16,000

The multiplier of 2.5 represents the remaining period of a 2.5-year initial visa grant. The £16,000 is a baseline amount that is always excluded from the calculation. In other words, the first £16,000 of your savings does not count towards the financial requirement.

Example Calculation

Suppose the income threshold for your application is £29,000, and your gross annual salary is £24,000. Your shortfall is £5,000 per year.

  • Income shortfall: £29,000 - £24,000 = £5,000
  • Multiply by 2.5: £5,000 x 2.5 = £12,500
  • Add the £16,000 baseline: £12,500 + £16,000 = £28,500

You would need to show at least £28,500 in cash savings, held for a minimum of 6 months, in addition to your employment income evidence.

Another Example

If the threshold is £29,000 and you earn £27,500:

  • Income shortfall: £29,000 - £27,500 = £1,500
  • Multiply by 2.5: £1,500 x 2.5 = £3,750
  • Add £16,000: £3,750 + £16,000 = £19,750

The closer your income is to the threshold, the less savings you need.

What Counts as Cash Savings?

Not all assets qualify. The Home Office accepts the following as cash savings:

  • Current accounts and savings accounts held at banks or building societies
  • Fixed-term deposit accounts, provided the funds can be accessed (with or without a penalty for early withdrawal)
  • Cash ISAs (not stocks and shares ISAs)

The following do not count:

  • Property or land equity
  • Stocks, shares, or investment portfolios
  • Pension funds
  • Cryptocurrency
  • Premium bonds (unless cashed in and held as cash for 6 months)
  • Money owed to you by other people

The 6-Month Holding Requirement

Your savings must have been held for at least 6 months before the date of your visa application. The full amount must be present in the account (or accounts) throughout that entire period. If the balance dips below the required amount at any point during the 6 months, the Home Office may refuse your application.

For example, if you apply on 1 June 2026, you need to show bank statements from 1 December 2025 to 1 June 2026 demonstrating that the required balance was maintained throughout.

Small fluctuations due to interest payments or bank charges are generally acceptable, but any significant unexplained drop will raise questions. The safest approach is to ensure the account balance never falls below the required amount during the 6-month window.

Whose Savings Can You Use?

You can use savings belonging to:

  • The UK-based sponsor
  • The applicant (the person applying for the visa)
  • Both partners jointly (e.g., a joint bank account)

If savings are split across multiple accounts or held by different people, you must provide bank statements for every account you are relying on. Each account must show the required 6-month holding period. For joint accounts with third parties (e.g., a parent), the Home Office will generally only accept the applicant's or sponsor's share.

Evidence You Need to Provide

When combining income and savings, you must submit evidence for both sources:

Income Evidence

For salaried employment, this typically includes payslips covering 6 months, a letter from your employer confirming your salary and role, and bank statements showing salary deposits. See our financial categories guide for details on what evidence applies to your situation.

Savings Evidence

  • Bank statements covering the full 6-month period
  • Statements must be on official bank letterhead or printed from an online banking system
  • Each statement must show the account holder's name, the account number, the dates covered, and all transactions
  • If the account is in a foreign currency, provide the balance in that currency (the Home Office will convert it)
  • If statements are not in English, provide a certified translation

Common Mistakes to Avoid

Applications using the combined income and savings route are scrutinised closely. These are the most common errors:

  • Balance dipping below the threshold: Even a single day below the required amount can lead to refusal. Monitor your account throughout the 6-month period.
  • Unexplained large deposits: A sudden lump sum deposited shortly before the 6-month window begins looks suspicious. If someone gifted you money, include a signed letter explaining the gift.
  • Missing bank statements: You must cover every single day of the 6-month period. Gaps in statements will be flagged.
  • Using the wrong threshold: Make sure you calculate the shortfall against the correct threshold for your application. Check the transitional arrangements to confirm which threshold applies to you.
  • Forgetting the £16,000 baseline: Some applicants forget to add £16,000 to their calculation and show insufficient savings.

Using Savings Alone (Without Income)

If the sponsor has no income at all, you can rely entirely on savings. The formula changes slightly. You need to hold savings of at least:

(Full threshold amount x 2.5) + £16,000

For a £29,000 threshold, this would be (£29,000 x 2.5) + £16,000 = £88,500. This is a substantial amount, which is why most applicants prefer to combine income and savings rather than relying on savings alone.

The same 6-month holding period and evidence requirements apply. The savings must be in cash form and accessible.

How the Home Office Verifies Savings

Caseworkers review bank statements line by line. They check that the required balance was maintained on every date within the 6-month window. They also look for patterns that suggest the money was temporarily placed in the account to meet the requirement (sometimes called "funds parking").

If the caseworker has concerns, they may contact your bank directly to verify the statements. Providing false or misleading bank statements is a criminal offence and will result in your application being refused, with a potential ban on future applications.

Tips for a Strong Application

  • Start building your savings well in advance. Ideally, have the required amount in your account at least 7 months before you plan to apply, giving yourself a buffer.
  • Keep your savings in one account if possible. This makes the evidence simpler and reduces the chance of errors.
  • Do not move large sums in or out of the account during the 6-month period unless absolutely necessary.
  • Double-check your calculation before submitting. Use the formula carefully and make sure you are using the correct income threshold for your application type.
  • If in doubt about your evidence, consult an immigration solicitor before submitting. A refused application costs far more than professional advice.
