About WealthSum

WealthSum is a free set of investing and trading calculators. We built it because most calculator sites work in one currency, cap the amounts you can enter, hide useful options on separate pages, and push you to invest with them at the end.

What we promise

• Every currency. Pick from more than 150 currencies and show numbers in lakh/crore or million/billion.
• No limits. Type any amount, including short forms like 50L, 1Cr or 10M.
• The whole picture. Year-by-year tables with 25 more years after your plan.
• Open formulas. Every page shows the formula and a worked example, and lets you switch how the yearly return is applied, so you can see why sites disagree.
• Private by design. Calculations run in your browser. We do not store what you type.
• No sales pitch. We do not sell funds or recommend investments.

How we check the numbers

Every formula is tested against published examples from widely used calculators and against spreadsheet results before release. If you spot an error, please tell us and we will fix it.
