Formula Used: This calculator uses a future value of an annuity formula to project the total capital accumulation over the term, considering interest and fees. The annual payment is then derived by dividing the accumulated value (minus fees) by the number of payment periods within the annuity term. Specific annuity payout calculations can vary based on product features like guarantees, inflation protection, and death benefits.

What is a Legal and General Annuity?
A legal and general annuity calculator is a financial tool designed to help individuals estimate the potential retirement income they could receive from purchasing an annuity, often from providers like Legal & General. Annuities are insurance contracts that provide a guaranteed stream of income, typically during retirement, in exchange for a lump sum payment. They are a popular option for individuals seeking financial security and predictable income in their later years, ensuring a consistent source of funds to cover living expenses.
Who should use it: Individuals approaching retirement or those who have accumulated a significant lump sum (e.g., from pensions, savings, or investments) and are looking for a way to convert this into a stable, regular income. It's particularly useful for those who are risk-averse and prefer guaranteed returns over market volatility. Using a legal and general annuity calculator allows for preliminary planning and comparison of different potential annuity scenarios.
Common misconceptions:
Annuities are only for the wealthy: While larger lump sums generally result in higher income, annuities can be structured for various investment amounts.
Annuities offer poor returns: Some annuities can offer competitive rates, especially when compared to low-interest savings accounts, and provide valuable guarantees.
All annuities are the same: There are various types of annuities (e.g., fixed, inflation-linked, joint-life) with different features and payout structures. A legal and general annuity calculator helps illustrate the impact of different assumptions.
Annuity income is fixed forever: Some annuities can be purchased with inflation protection, meaning the income increases over time to combat rising living costs.
Legal and General Annuity Calculator Formula and Mathematical Explanation
The core of a legal and general annuity calculator involves projecting the growth of the initial lump sum and then determining the regular payout. This calculation often leverages the concept of the Future Value of an Ordinary Annuity, adjusted for fees and payment frequencies.
Step-by-step derivation:
Calculate the Periodic Interest Rate: The annual rate of return is divided by the number of payment periods per year.
Periodic Rate (i) = Annual Rate of Return / Payment Frequency
Calculate the Total Number of Periods: The annuity term in years is multiplied by the number of payment periods per year.
Total Periods (n) = Annuity Term (Years) * Payment Frequency
Calculate the Future Value of the Lump Sum (FV_LS): The initial lump sum grows with compound interest over the annuity term, before any payments are made.
FV_LS = Lump Sum * (1 + i)^n
Calculate the Future Value of the Annuity Payments (FV_P): This is the future value of a series of payments made at regular intervals. The formula for the future value of an ordinary annuity is:
FV_P = P * [((1 + i)^n - 1) / i] Where 'P' is the periodic payment. However, in a calculator that determines the payout, we work backward. The total accumulated value available for payouts is the FV_LS after accounting for fees.
Calculate Total Fees: Annual fees are deducted each year, impacting the growth. This is complex to model precisely in a simple formula, so calculators often simplify by deducting fees periodically or amortizing them. A common simplification is to calculate the effective rate after fees:
Effective Periodic Rate = (1 + Periodic Rate) * (1 - Annual Fees / 100) - 1 Or, a simpler approach is to calculate total fees at the end based on the accumulated capital or average capital. For this calculator's approach, we'll estimate based on annual deduction from the growing balance.
Determine the Periodic Payment (P): The total capital available at the end of the term (initial lump sum grown, minus total fees) is divided by the number of payment periods to determine the income per period. A more accurate calculation involves treating the annuity as a present value problem where the lump sum is the present value, and we solve for the payment 'P'.
Present Value (PV) = P * [1 - (1 + i)^-n] / i Rearranging to solve for P (Periodic Payment):
P = PV * [i * (1 + i)^n] / [(1 + i)^n - 1] This formula calculates the payment 'P' assuming the PV is the initial lump sum, and 'i' and 'n' are adjusted for compounding frequency. Fees are usually deducted from the investment, reducing the effective growth rate. For simplicity in this calculator, we'll estimate the final pot and then distribute it.
Simplified Calculation Logic for the Calculator:
The calculator models the year-by-year growth and fee deduction to determine the final pot available. Then, it calculates the payout.
Total Value at End of Term = Lump Sum * (1 + Effective Annual Growth Rate) ^ Annuity Term
Total Fees Paid = Total Value at End of Term * (Fees Percentage / 100) (Simplified approximation)
Net Capital Available = Total Value at End of Term - Total Fees Paid
Periodic Payment = Net Capital Available / Total Periods
Estimated Annual Income = Periodic Payment * Payment Frequency
Total Payments Received = Estimated Annual Income * Annuity Term

Practical Examples (Real-World Use Cases)
Understanding how a legal and general annuity calculator works is best done through examples.
Example 1: Steady Income for Fixed Term
Scenario: Sarah, aged 65, has £75,000 in savings she wants to use to supplement her state pension. She wants a guaranteed income for 15 years and believes a modest 3% annual return is achievable, with 1.2% annual fees.
Inputs:
Lump Sum: £75,000
Annuity Term: 15 years
Expected Annual Rate of Return: 3.0%
Payment Frequency: Monthly (12)
Annual Fees: 1.2%
Using the calculator:
Estimated Annual Income: Approximately £6,500
Total Payments Received: Approximately £97,500
Total Fees Paid: Approximately £14,500
Main Result (Monthly Income): Approximately £542
Financial Interpretation: Sarah can secure a monthly income of roughly £542 for 15 years. While the total payments (£97,500) exceed her initial investment, this accounts for the assumed growth and the cost of fees and guarantees over the period.
Example 2: Maximising Income with Higher Investment
Scenario: John, aged 68, has £150,000 from a pension transfer. He wants to maximise his guaranteed income for 10 years, accepting a slightly higher potential return of 4.5% annually, but with lower fees of 0.8%.
Inputs:
Lump Sum: £150,000
Annuity Term: 10 years
Expected Annual Rate of Return: 4.5%
Payment Frequency: Annually (1)
Annual Fees: 0.8%
Using the calculator:
Estimated Annual Income: Approximately £19,200
Total Payments Received: Approximately £192,000
Total Fees Paid: Approximately £16,500
Main Result (Annual Income): Approximately £19,200
Financial Interpretation: John's larger lump sum and favourable assumptions (higher rate, lower fees) result in a significantly higher annual income of £19,200 compared to Sarah's scenario. This highlights the impact of investment amount and terms on annuity payouts. A key factor for John is understanding how pension drawdown might compare.

Key Factors That Affect Legal and General Annuity Results
Several factors significantly influence the income generated by a legal and general annuity. Understanding these helps in using the calculator more effectively and making informed decisions:
Annuity Provider's Financial Strength: The stability and financial health of the provider (like Legal & General) are paramount. A stronger provider is more likely to meet its long-term payment obligations.
Interest Rate Environment: Annuity payouts are heavily influenced by prevailing interest rates at the time of purchase. Higher interest rates generally lead to higher annuity income, as they reflect better potential investment returns.
Your Age and Health: For lifetime annuities, your age and life expectancy (and that of a spouse, if applicable) are critical. Certain health conditions might qualify you for 'enhanced annuities' which pay out more due to a shorter life expectancy.
Guarantees and Features: Options like guaranteed annuity rates (GARs), inflation protection (linking income to RPI/CPI), and guaranteed payout periods or death benefits can significantly impact the initial income. These features often reduce the immediate payout in exchange for future security.
Investment Growth Assumptions: The 'Expected Annual Rate of Return' is a major driver. Overly optimistic assumptions can lead to disappointment, while conservative estimates might undervalue the potential income. The calculator uses this to project growth before payouts.
Fees and Charges: Even seemingly small annual fees (like the 1.0% in the calculator) compound over time and can substantially reduce the total income received, as illustrated in the results. Transparency in charges is crucial when comparing annuity products.
Taxation: While annuity income is taxable, the specific tax treatment depends on your individual circumstances and the type of pension fund used to purchase the annuity. This calculator does not include tax implications.
Inflation Risk: If your annuity payments are fixed, their purchasing power will decrease over time due to inflation. Annuities with inflation protection mitigate this but typically offer lower initial payouts.
Frequently Asked Questions (FAQ)
What is the difference between a lifetime annuity and a fixed-term annuity?
A lifetime annuity provides income for the rest of your life, regardless of how long you live. A fixed-term annuity pays out for a specified number of years (e.g., 10, 15, 20 years) and then stops. Our calculator primarily focuses on fixed-term scenarios for illustrative purposes, but lifetime annuities are common.
Can I get my lump sum back if I buy an annuity?
Typically, once you purchase a lifetime annuity, the lump sum is converted into income and cannot be reclaimed. Fixed-term annuities may offer options for capital protection or withdrawal at the end of the term, but this often reduces the income during the term.
What does 'Guaranteed Annuity Rate' (GAR) mean?
A Guaranteed Annuity Rate (GAR) is a rate offered on certain older annuity policies that is higher than current market rates. If you have a policy with a GAR, it's usually very beneficial to use it rather than buying a new annuity. This calculator assumes current market rates unless a specific GAR feature is factored in.
How does inflation affect my annuity income?
Inflation erodes the purchasing power of money over time. If your annuity payments are fixed, each year they will buy less. Annuities with inflation protection adjust payments upwards annually, usually by a set percentage or in line with an inflation index like the CPI, but this typically results in a lower starting income.
Can I use my pension pot to buy an annuity?
Yes, using your pension pot to purchase an annuity is one of the primary ways to convert retirement savings into a guaranteed income stream. This is often referred to as 'annuitisation'.
What are the risks associated with annuities?
Key risks include: inflation risk (if income isn't inflation-linked), interest rate risk (locking in low rates), provider insolvency (though regulated providers are financially robust), and opportunity cost (missing out on potentially higher returns from other investments). Annuities also offer less flexibility compared to drawdown.
How can I compare annuity rates from different providers like Legal & General?
You can use annuity comparison services or financial advisors. Our legal and general annuity calculator provides an estimate based on your inputs, but it's crucial to get personalised quotes from multiple providers, as rates can vary significantly based on individual circumstances and the specific product features offered.
Does this calculator provide financial advice?
No, this calculator is a tool for estimation and illustration purposes only. It does not constitute financial advice. Decisions about purchasing annuities should be made in consultation with a qualified financial advisor who can assess your personal circumstances, risk tolerance, and retirement goals.
