Gifting 3,000 a year for 20 years removes 60,000 from your estate, saving 24,000 of inheritance tax at a 40% rate. Layered with spouse allowances and small-gift exemptions, families can shift meaningful wealth without triggering tax.
Quick example
With annual gift allowance of 3,000 and inheritance/gift tax rate of 40% (plus years used of 20), the result is 24,000.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Annual Gift Allowance, Inheritance/Gift Tax Rate, and Years Used. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
What's happening under the hood
Total tax saved equals annual allowance times years used times the would-be tax rate. Compounding effects in the recipient's investments are not modelled. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why small rate shifts add up
A 3% pay rise looks modest. Apply it over a 30-year career with modest promotions and the lifetime difference runs to six figures. This calculator makes that invisible compounding visible in a way spreadsheets usually don't.
What this doesn't capture
Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the pension carry forward value calculator, the annual leave value calculator, and the charitable donation tax relief calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
Total tax saved over this period is the figure shown above.
