Why this matters: Education costs rise with inflation and the type of course (domestic vs overseas). Starting early and choosing the right savings route—regular SIPs in mutual funds for growth or PPF for guaranteed returns—helps parents meet future education expenses without stress. This guide shows formulas, worked examples, and a clear comparison so you can decide and use our calculators to personalise the plan.
Step 1 — Estimate the Future Cost of Education
Start with the current estimated cost for the course today and inflate it to the year your child will need the money.
Future Cost = Present Cost × (1 + inflation_rate) ^ years_to_need
Worked example — Projecting fees (digit-by-digit)
Assume:
- Present cost for a 4-year undergraduate program: ₹10,00,000
- Years until college start: 10 years
- Assumed inflation in education fees: 6% per year
Compute future cost step-by-step:
Step 1: 1 + inflation = 1 + 0.06 = 1.06 Step 2: (1.06)^10 ≈ 1.7908476965428547 Step 3: Future Cost = 10,00,000 × 1.7908476965428547 ≈ ₹17,90,847.70
Result: The ₹10,00,000 education today ≈ ₹17,90,848 in 10 years (rounded).
Step 2 — Choose saving route(s) and calculate required savings
Common approaches:
1) SIP (Systematic Investment Plan)
Use SIPs for higher expected returns (equity). Use the SIP future value formula to find required monthly contribution.
FV = P × [ ( (1 + r)^n − 1 ) / r ](where P=monthly SIP, r=monthly rate, n=months)
2) PPF (Public Provident Fund)
PPF is a government-backed option with yearly contributions and guaranteed returns (good for capital preservation). Use the annual annuity formula to compute required yearly deposit.
FV = A × [ ( (1 + R)^N − 1 ) / R ](where A=annual deposit, R=annual rate, N=years)
Worked calculations (useful example — digit-by-digit)
Target lump sum = ₹17,90,848 (from earlier). We'll calculate:
- Monthly SIP required if expected return = 12% p.a.
- Annual PPF deposit required if assumed PPF return = 7.1% p.a.
A — Monthly SIP (assumptions)
- Target FV = ₹17,90,847.70
- Annual return = 12% → monthly r = 0.12 / 12 = 0.01
- Years = 10 → n = 10 × 12 = 120 months
Compute (1 + r)^n:
1 + r = 1 + 0.01 = 1.01 (1.01)^120 ≈ 3.3003868945736685
Compute factor = ((1 + r)^n − 1) / r:
(1.01)^120 − 1 = 3.3003868945736685 − 1 = 2.3003868945736685 Divide by r: 2.3003868945736685 ÷ 0.01 = 230.03868945736684
Monthly SIP (P) = FV / factor:
P = 1,790,847.70 ÷ 230.03868945736684 ≈ ₹7,784.98
Result: You need approximately ₹7,785 per month in SIP at 12% p.a. to reach ₹17.91 lakh in 10 years.
B — Annual PPF deposit (assumptions)
- Target FV = ₹17,90,847.70
- Assumed PPF return = 7.1% → R = 0.071
- Years = 10 → N = 10 (note: PPF minimum lock-in is 15 years, but this example uses 10 years for calculation clarity — adjust as per scheme rules)
Compute (1 + R)^N:
1 + R = 1 + 0.071 = 1.071 (1.071)^10 ≈ 1.9856134608011426
Compute factor = ((1 + R)^N − 1) / R:
(1.9856134608011426 − 1) = 0.9856134608011426 Divide by R: 0.9856134608011426 ÷ 0.071 ≈ 13.88187972959356
Annual deposit A = FV / factor:
A = 1,790,847.70 ÷ 13.88187972959356 ≈ ₹1,29,006.14
Result: You would need approximately ₹1,29,006 per year in PPF at 7.1% to reach the target in 10 years (again, check actual PPF tenure and rules — PPF typically requires 15-year maturity).
Comparison table — SIP vs PPF (example)
| Approach | Assumed Return | Contribution | Time | Approx. Contribution Required |
|---|---|---|---|---|
| Monthly SIP (equity) | 12% p.a. (assumed) | Monthly | 10 years | ~ ₹7,785 / month |
| Annual PPF (guaranteed) | 7.1% p.a. (assumed) | Yearly | 10 years | ~ ₹1,29,006 / year |
| Combination (50:50) | Blended | Monthly + Yearly | 10 years | ~ ₹3,900/month + ₹64,500/year (approx.) |
Which option should you pick?
- SIP (mutual funds) — Best if you accept market volatility for higher expected returns and have a longer horizon. Good when you can increase SIP amounts over time.
- PPF — Good for capital preservation and guaranteed returns. Useful for risk-averse parents, but check lock-in (typically 15 years) and liquidity rules.
- Combination — Many parents split the goal: use SIPs for growth and PPF for a safe portion; this reduces overall risk while keeping potential upside.
- Start early — even small SIPs grow significantly due to compounding.
- Revisit assumptions (inflation & returns) annually and step up contributions when income rises.
- Build an emergency corpus separately — do not use education savings for unrelated emergencies.
- Use the calculators below to test multiple scenarios quickly (different inflation, returns, time horizons).

Frequently asked questions
Q: What inflation rate should I assume for education?
A: Education inflation has historically been higher than general inflation. Many planners use 6%–8% for fees — use conservative assumptions and run multiple scenarios.
Q: Is PPF allowed for education withdrawals?
A: PPF has specific withdrawal and loan rules; usually withdrawals allowed after 7 years subject to conditions. Check current government rules before relying on PPF liquidity.
Q: Can I combine SIP and PPF?
A: Yes. Combining gives growth potential from SIPs and stability from PPF. Allocate based on risk tolerance and timelines.
