UK Financial Calculators for Stamp Duty, Redundancy, Inheritance, Pensions and Tax
This page brings together practical UK financial calculators with simple layouts, clear field explanations and search-friendly content written for real users. The design uses a Money Legal Experts inspired card layout with Nunito only, fixed heading sizes and strong call-to-action buttons. Where a repayment or interest-only toggle is not meaningful because the calculator is tax or entitlement based, the page says so clearly rather than forcing an inaccurate credit assumption.
Stamp Duty Calculator
Estimate Stamp Duty Land Tax for residential property in England and Northern Ireland, including first-time buyer relief, higher rates for additional properties and the non-UK resident surcharge.
How this stamp duty calculator works
This UK stamp duty calculator applies the current residential SDLT bands for England and Northern Ireland, then layers on any first-time buyer relief or additional property and non-resident surcharges. It is written to help buyers compare purchase budgets and upfront buying costs before making an offer or mortgage application.
Field explanations
Credit Card Interest Calculator
Estimate how long a balance could take to clear, how much interest you could pay and how an introductory interest-free offer can affect the total cost.
How this credit card interest calculator works
This UK credit card calculator helps compare balances, APRs, monthly payments and promotional periods. It includes an interest-free offer period and a fee field because those are often the deciding factors when comparing balance transfer cards and purchase cards. The interest-only style option estimates a low-payment scenario for users who want to see how expensive slow repayment can become.
Field explanations
Redundancy Calculator
Estimate statutory redundancy pay, taxable and non-taxable elements, and a simple year-end tax view based on pay already received and when the payment is made.
How this redundancy calculator works
This UK redundancy calculator first estimates statutory redundancy pay using age bands, service caps and the current capped weekly pay approach, then separates tax-free redundancy elements from taxable earnings such as PILON. It also includes a payment month and pay-to-date field because PAYE timing can affect whether someone appears to have overpaid tax and may later be due a rebate.
Tax and rebate explainer
Statutory redundancy pay and qualifying enhanced redundancy payments are usually tax free up to a combined £30,000. Wages, holiday pay and PILON are generally taxable as earnings. If you stop work and have paid too much tax, a rebate may be possible, often via HMRC forms or the year-end reconciliation process, especially where you do not return to work or taxable benefits do not continue.
Field explanations
Inheritance Calculator
Estimate a simple inheritance tax exposure, apply nil-rate bands and show how the net estate could be split between multiple recipients.
How this inheritance calculator works
This UK inheritance tax calculator applies the standard nil-rate band, optional transferable allowances from a spouse or civil partner, and the residence nil-rate band where a qualifying home passes to direct descendants. It then shows an estimated inheritance tax bill and the net amount left for the chosen number of beneficiaries.
Threshold indicators and tax explainer
The nil-rate band is fixed at £325,000, the residence nil-rate band at £175,000, and the residence band tapers away once the net estate exceeds £2 million. Where unused spouse or civil partner bands transfer in full, combined allowances can reach up to £1 million in qualifying cases. Amounts above available thresholds are generally taxed at 40% in a simple estate calculation.
Field explanations
Pension Calculator
Estimate annual and monthly pension contributions, total funding, basic tax relief and how close total input is to the current annual allowance.
How this pension calculator works
This UK pension calculator shows what the individual is paying in, what the employer is contributing and the overall annual and monthly funding level. It also compares total pension input with the current annual allowance so users can spot when they may need more detailed advice, especially if they have other schemes or high income.
Tax explainer
For 2025 to 2026, the standard annual allowance is £60,000 and the money purchase annual allowance is £10,000 for people who have flexibly accessed pension benefits. Tax relief on personal contributions is usually available up to 100% of UK taxable earnings or £3,600 if higher-level earnings are not available.
Field explanations
Capital Gains Tax Calculator
Estimate Capital Gains Tax using your gain, losses, taxable income and the current annual exempt amount. Includes a residential property toggle.
How this capital gains tax calculator works
This UK capital gains tax calculator works out the gross gain, deducts losses and the annual exempt amount, then applies the correct rate mix depending on how much unused basic-rate band remains once your taxable income has been taken into account. It is designed for individuals who want a quick estimate before filing or speaking to an adviser.
Tax explainer
For 2025 to 2026, the annual exempt amount for most individuals is £3,000. From 6 April 2025 onwards, individuals generally pay Capital Gains Tax at 18% or 24% depending on how much of the gain falls within the unused basic-rate band. This simplified calculator uses those rates.
