The NPS Calculator helps you estimate your retirement corpus, monthly pension, and tax savings under India’s National Pension Scheme (NPS). By entering your age, monthly contribution, and expected rate of return, this tool instantly shows your future pension benefits
What is NPS and How It Works?
The National Pension System (NPS) is a government-backed retirement savings scheme designed to help individuals build a retirement corpus and receive a regular pension post-retirement with 2 different Tier's. It is suitable for both salaried and self-employed individuals who want a disciplined long-term investment plan with tax benefits.
Tier 1 vs Tier 2 Accounts:
- Tier 1 Account: This is the primary NPS account, primarily for retirement savings. Withdrawals are restricted until retirement, but contributions qualify for tax benefits under Section 80C (up to ₹1.5 lakh) and Section 80CCD(1B) (additional ₹50,000).
- Tier 2 Account: This is a voluntary savings account with flexible withdrawals and no mandatory lock-in. While it offers investment flexibility, contributions do not qualify for tax deduction like Tier 1.
What is the NPS Calculator?
The NPS Calculator is an online tool designed to estimate your retirement corpus and monthly pension through the National Pension System. It also highlights potential tax savings under Sections 80CCD(1) and 80CCD(1B) of the Income Tax Act, as well as the tax-free benefits associated with lump sum withdrawals.
How Does the NPS Calculator Work?
The NPS calculator works by taking basic inputs such as your monthly contribution, age, expected rate of return, and chosen annuity percentage to estimate your retirement corpus. It shows your total investment, projected future value at retirement, and the potential tax-free lump sum you can withdraw (up to 60%).
It also calculates the estimated monthly pension you'll receive for life based on the annuity purchased. Additionally, after the subscriber's demise, 40% of the corpus used for annuity is transferred to the nominee.
NPS Calculator Formula
NPS Pension amount can be calculated by using the following formula
Future Value (FV) = C/[ (1 + r/n)^(nt) – 1 \] / (r/n)
- PV = Future Value
- C = Monthly Contribution
- r = Rate of Return
- n = Number of Years
- t = Years left for Retirement
Example of NPS Calculator
Consider an example to understand how the NPS calculator computes the monthly pension.
- Subscriber: Mr A, age 21, Central Government employee
- Monthly Contribution: ₹3,600
- Investment Duration: 39 years (until age 60)
- Expected Annual ROI (during accumulation): 8%
- Annuity Purchase at Retirement: 40% of corpus
- Expected Annuity Return: 6%
Total Contribution Over 39 Years: ₹3,600 × 12 months × 39 years = ₹16,41,600
Projected Corpus at Retirement: Based on an 8% annual return, the corpus at age 60 is projected to be ₹1,07,06,420
Lump Sum Withdrawal (60% of corpus): 60% of ₹1,07,06,420 = ₹64,23,852 (tax-free)
Annuity Purchase (40% of corpus): 40% of ₹1,07,06,420 = ₹42,82,568
Estimated Monthly Pension (based on 6% annuity return): Monthly Pension = ₹21,413
How to Use the NPS Calculator?
The calculator needs the following information to determine how much corpus you will accumulate:
- Enter your monthly investment amount.
- Add your current age.
- Add your expected return on investment.
- Enter the percentage of annuity purchase.
- Add the expected return of the annuity.
