Calculate maturity value and returns for India's three most popular Post Office savings schemes — NSC, KVP, and SCSS. Rates last reviewed: July 2026.
Choose a Scheme & Enter Details
Select NSC, KVP, or SCSS above, fill in your investment amount and rate, then click Calculate.
The Post Office Savings Calculator projects returns for three of India's most widely used government-backed small savings schemes in one tool: the NSC calculator mode for National Savings Certificates, the KVP calculator mode for Kisan Vikas Patra, and the SCSS calculator mode for the Senior Citizen Savings Scheme. All three are offered through India Post and authorised banks, and are popular for their sovereign backing and predictable, quarterly-revised returns compared to market-linked investments.
Switch between the three modes using the toggle above the form. NSC and KVP both compound annually, so the calculator applies the compound interest formula to project the maturity value at the end of the scheme's fixed term (or, for KVP, at your own custom tenure). KVP additionally derives its doubling period — the number of years and months it takes your investment to double — directly from the interest rate you enter, using the standard compound-interest doubling formula. SCSS works differently: interest is simple, not compounded, and paid out every quarter directly to the investor rather than added back to the principal, so the calculator shows your quarterly payout, annual payout, and total interest received over the tenure, with your principal returned unchanged at maturity.
This tool suits salaried taxpayers looking for a guaranteed Section 80C investment (NSC), risk-averse savers who like the simplicity of a "money doubles" promise (KVP), retirees or soon-to-retire individuals wanting predictable quarterly income (SCSS), and anyone comparing these government-backed schemes against a bank FD or RD before committing funds.
Post office schemes remain a cornerstone of conservative, risk-free savings in India — especially for retirees relying on SCSS for steady quarterly income, or investors using NSC for a guaranteed 80C tax-saving investment alongside their PPF and ELSS allocations. Because interest rates are revised quarterly by the Ministry of Finance and each scheme has meaningfully different compounding, payout, and tax rules, it's easy to misjudge the real return by treating them as interchangeable. This calculator makes the maturity value, doubling period, and payout schedule concrete before you commit funds for years at a time.
Each scheme uses a different interest structure
National Savings Certificate locks your money for 5 years, compounding annually but paying interest only at maturity. It qualifies for Section 80C deduction in the year invested, making it popular with salaried taxpayers.
Kisan Vikas Patra is designed around a simple promise: your money doubles in a fixed number of months at the prevailing rate. No 80C benefit, but no maximum investment limit either.
Senior Citizen Savings Scheme pays interest out every quarter rather than compounding it, making it a favorite for retirees who need predictable income. Capped at ₹30 lakh, with a 5-year tenure extendable once by 3 years.
From scheme selection to maturity value in under a minute
Select NSC, KVP, or SCSS using the toggle at the top of the calculator, depending on which India Post savings scheme you want to evaluate.
Input the amount you plan to invest — minimum ₹1,000 for all three schemes, with a ₹30 lakh cap for SCSS specifically.
Enter the current quarterly-notified rate for your chosen scheme from the India Post or National Savings Institute website — the pre-filled rate is illustrative only.
For KVP, optionally enter a custom tenure to see the value before the full doubling period. For SCSS, enter the tenure in years (standard is 5, extendable once by 3).
See the maturity value (NSC), doubling period and maturity value (KVP), or quarterly/annual payout and total interest (SCSS), along with charts and a year-wise or quarter-wise breakdown table.
Realistic NSC, KVP, and SCSS calculations using this calculator's own default values
Suppose you invest ₹1,00,000 in NSC at 7.7% annual interest, compounded annually over the fixed 5-year lock-in — this calculator's own NSC defaults.
Suppose you invest ₹1,00,000 in KVP at 7.5% annual interest — this calculator's own KVP defaults, with a 5-year custom tenure check.
Suppose a senior citizen invests ₹15,00,000 in SCSS at 8.2% annual interest over the standard 5-year tenure — this calculator's own SCSS defaults.
Explanation: These three examples show how differently the schemes behave even at similar rates. NSC locks your money and compounds it silently for exactly 5 years, ideal for a set-and-forget tax-saving goal. KVP makes no fixed-term promise at all — it simply doubles your money over however long the current rate implies, useful for open-ended goals. SCSS never grows your principal; instead it converts it into a steady quarterly paycheck, which is precisely why it's the go-to scheme for retirees who need income rather than growth.
What your scheme's return actually tells you, and how it fits alongside other options
Since NSC, KVP, and SCSS serve different purposes, the useful comparison isn't purely rate-based — it's whether the scheme's income shape (grow-and-collect vs. doubling vs. quarterly payout) matches what you actually need the money to do.
| Your Priority | Best-Fit Scheme | Why |
|---|---|---|
| Guaranteed tax deduction + growth | NSC | Section 80C eligible, compounds annually, fixed 5-year term |
| Simple long-term doubling, no fixed term | KVP | No 80C benefit, but flexible tenure and no investment cap |
| Steady quarterly income in retirement | SCSS | Highest typical rate of the three, but capped at ₹30 lakh and age-restricted |
For tax-conscious savers: NSC's Section 80C deduction effectively boosts your real return if you're in a higher tax bracket and haven't exhausted your ₹1.5 lakh 80C limit elsewhere — factor that in alongside the maturity value shown.
For retirees: SCSS's quarterly payout structure is built for spending, not compounding — compare its payout against a senior-citizen bank FD's interest income, and remember the ₹30 lakh cap may mean SCSS is only part of a larger retirement-income allocation.
Risk considerations: this calculator assumes your entered rate holds for the entire tenure, though real rates are only locked in at the time of investment and don't change afterward — new investments each quarter get whatever rate is then current. It doesn't model premature-closure penalties, TDS deduction mechanics, or the SCSS extension period's separate rate. Use the result as a planning estimate, not a certificate-ready figure.

Where NSC, KVP, and SCSS each earn their keep
Check how much an NSC investment reduces your taxable income while it grows toward maturity.
Model SCSS's quarterly payout as a predictable income stream alongside a pension or annuity.
Use KVP to see exactly how many years it takes a lump sum to double at the current rate.
Compare NSC or SCSS maturity/payout figures against a bank fixed deposit at the same amount.
Decide whether a lump-sum bonus is better placed in NSC, KVP, or a bank FD for your time horizon.
Use NSC's fixed lock-in to plan around a known 5-year milestone like a child's education fund.
Size SCSS's quarterly payout against expected recurring medical or living expenses.
KVP remains popular in semi-urban and rural India for its simple doubling promise with no paperwork complexity.
Size the guaranteed, sovereign-backed portion of a broader investment portfolio using any of the three schemes.
Estimate whether extending SCSS by 3 more years after the initial 5-year term still makes sense at the new rate.
Compare NSC (working years) against SCSS (retirement years) as a family plans savings across life stages.
