Gold and finance calculators
Every tool here runs in your browser from figures you type in. There is no live gold price and no sign-up — which means you supply the rate, and in return what you enter is not sent to us. Every result is an estimate, and each page shows the formula behind it.

Gold tools — work anywhere
Weights, purity and gold value do not change by country. These take the figures you enter and show the arithmetic, so they work whatever currency or market you are buying in. None of them assumes a tax rule.
Gold Loan EMI Calculator
Estimate monthly payments for gold loans with custom interest rates and tenure
Gold SIP Calculator
Project the value of a fixed monthly gold investment from a yearly return you enter
Purity Converter
Convert karat, fineness, and purity percentage for gold
Weight Converter
Convert gold weight between grams, tola, and troy ounces
Gold vs Silver Ratio
Divide the gold price by the silver price you enter and compare the ratio with its history
Gold Return Calculator
Check the profit, loss and yearly return on gold you already own from what you paid and a rate you enter
Gold tools for India
These two apply Indian conventions: rates quoted per 10 grams, and 3% GST on a jewellery invoice. If you are buying outside India the arithmetic still holds, but the tax line will not match your bill.
UK pension and tax tools
Calculators built on HMRC's rates, in pounds, with every rate linked to its gov.uk page. They have their own section, separate from the gold tools above.
Open the UK section → · Pension salary sacrifice calculator → · Student loan repayment calculator →
For Indian government employees
Pension and pay tools for central and state government staff. These depend on Indian service rules, so they have their own section with the sources and the official position set out alongside them.
NPS Pension Calculator
Calculate retirement corpus, VRS eligibility, and pension with monthly compounding
8th CPC Pay Calculator
Estimate salary under 8th Pay Commission with fitment factor and arrears
Pension Commutation Calculator
Lump sum, pension left and restoration date for central government pensioners
What these tools will not do
- Fetch a live gold or silver price — you enter the rate you were quoted.
- Tell you whether to buy, sell or hold. Nothing here is financial advice.
- Replace your jeweller's invoice or your department's own figures.
Each calculator's formula, assumptions and limits are written out in the methodology.
