About StepupCalculator
Free, accurate, and beautifully designed financial calculators built specifically for Global investors — with zero clutter.
Why I Built This
Most DCA calculators online are either too basic (no sign of step-up or inflation tracking) or buried inside apps that require sign-up. I wanted a single, fast, honest tool that shows the real numbers — including how inflation erodes your returns and how a small annual step-up dramatically changes your final corpus over decades.
About the Creator
Built by Rajat — a professional software developer and passionate personal finance advocate. Frustrated by the lack of transparent, accurate financial tools available to retail investors, Rajat combined his technical expertise with rigorous financial mathematics to build StepupCalculator. The goal? To make institutional-grade financial planning accessible to everyone, completely free of charge.
Our Editorial & Accuracy Standards
We hold ourselves to the highest standards of mathematical accuracy and transparency. When dealing with your money and your life's savings, "close enough" is not acceptable.
- Standardized Mathematics: The formulas used for our DCA calculations strictly follow standard financial mathematics — utilizing APR-based compounding with investments made at the beginning of each period. This ensures perfect alignment with historical market analysis and institutional projections.
- Transparent Methodology: We do not hide our math behind proprietary black boxes. Our formulas are openly documented and verifiable.
- No Conflicts of Interest: StepupCalculator is independently funded. We do not sell your email, we do not require sign-ups, and our calculator results are never artificially inflated to sell you financial products.
