Understanding Income Continuity & Maturity Risk in Retirement
Many senior citizens and conservative investors construct fixed-income portfolios by splitting money across Senior Citizens Savings Scheme (SCSS), Post Office Monthly Income Scheme (POMIS), National Savings Certificates (NSC), and Bank Fixed Deposits. However, portfolio cash flows are rarely static. Understanding maturity cycles and inflation dynamics is essential for financial longevity.
Maturity Cliff Risk
SCSS and POMIS expire every 5 years. When a ₹30 Lakh SCSS block matures, ₹2,0500/month of income stops instantly. Without a pre-planned reinvestment strategy, households face sudden cash-flow shocks.
Inflation Purchasing Power Erosion
Fixed income does not automatically grow with inflation. A fixed ₹50,000/month payout that easily covers expenses at age 60 will cover less than 56% of basic household living costs by age 70 at a 6% inflation rate.
Reinvestment Rate Risk
Interest rates offered by the Ministry of Finance and commercial banks fluctuate over multi-decade horizons. Reinvesting maturing principal during a low-interest environment reduces future monthly yields.

Start with the monthly paycheck you need (e.g. ₹50,000/mo) and work backwards to find required capital across SCSS, POMIS & FDs.
Frequently Asked Questions
What is the Sovereign Income Continuity Planner?
The Sovereign Income Continuity Planner is a specialized simulation tool designed for Indian retirees and income-seeking households. While traditional calculators only tell you today's interest payout, this planner models your fixed-income portfolio (SCSS, POMIS, NSC, FDs) across 10 to 30 years to check if your income will survive scheme maturities, inflation purchasing power loss, and future interest rate changes.
How does the planner handle scheme maturities (Income Cliffs)?
Government small savings schemes have fixed tenure limits: SCSS matures in 5 years (extendable by 3 years), POMIS matures in 5 years, and NSC matures in 5 years. When a scheme matures, your regular monthly paycheck drops immediately unless the capital is reinvested. The continuity planner highlights these exact maturity years as 'Income Cliffs' and calculates the exact gap created.
How is inflation factored into the income requirement?
Inflation erodes purchasing power over time. A household spending ₹50,000/month today will require approximately ₹89,542/month in 10 years at a 6.0% annual inflation assumption. The planner compounds your monthly requirement each year and compares it directly against your projected portfolio income.
What is the difference between this tool and the Guaranteed Income Reverse Planner?
The Guaranteed Income Reverse Planner answers: 'How much total capital do I need today to generate ₹50,000/month?'. The Income Continuity Planner answers: 'I already have ₹50 Lakh in SCSS, POMIS & FDs—will this income survive for the next 20 years through maturities and inflation?'.
What is the Income Continuity Score (0 to 100)?
The Income Continuity Score evaluates 5 core financial factors: Current Income Coverage, 10-Year Inflation Resilience, Maturity Cliff Staggering, Long-Term Reinvestment Safety, and Liquidity Buffer Availability. A score of 80+ indicates a resilient retirement cash-flow structure.
