The National Pension System (NPS) is a government-backed retirement scheme designed to offer long-term financial security to employees in India. For government employees, the NPS provides a flexible, tax-efficient way to save for retirement, with contributions matched by the government. Using the NPS calculator for government employees allows them to estimate their potential pension corpus and monthly pension income based on regular contributions, rate of returns, and retirement age. This article covers an overview of the NPS calculator, its usage, benefits, and a comparison with the private-sector NPS to help government employees make informed financial decisions.
