Systematic Transfer Plan (STP) Calculator
Calculate systematic transfers from a source fund (e.g. debt/liquid fund) to a target fund (e.g. equity fund) and track combined portfolio value.

What Is a Systematic Transfer Plan (STP)?
A Systematic Transfer Plan (STP) is an automated mutual fund strategy that allows an investor to periodically shift a predetermined amount of money from one mutual fund scheme (the source fund) to another scheme (the target fund) within the same Asset Management Company (AMC).
STP is most commonly utilized when an investor receives a significant lump sum (such as an annual bonus, property sale proceeds, or retirement gratuity). Rather than risking all the capital in the equity market at once or leaving it in a low-yield bank savings account, the investor parks the lump sum in a liquid or short-term debt fund (yielding 6%–7% p.a.) and sets up an automated monthly STP into diversified equity funds over 12 to 36 months.
How Does an STP Calculator Work?
An STP calculator models dual-fund financial mechanics across every month of the transfer timeline:
- Track Source Fund Balance: Accrues monthly interest on the un-transferred balance in the liquid/debt fund.
- Execute Monthly Transfer: Deducts the fixed monthly installment from the source fund.
- Credit Target Fund: Adds the installment to the equity target fund and compounds accumulated units at the equity return rate.
- Compute Combined Valuation: Evaluates the total combined wealth (Source Balance + Target Equity Value) at every monthly milestone.
How Is an STP Calculated?
For each month m from 1 to the duration:
Our financial calculation engine (calculateStp) executes this dual-fund simulation month by month to provide exact portfolio balances.
STP Calculation Example
Consider an investor with a ₹10 Lakh lump sum setting up a 3-year (36 months) STP:
- Source Fund (Liquid Fund): ₹10,00,000 initial, assumed 6% return p.a.
- Monthly Transfer Amount: ₹25,000 / month
- Target Fund (Equity Fund): Assumed 12% return p.a.
- Duration: 36 Months
By using an STP, the investor achieved complete rupee-cost averaging in equities while earning over ₹2.97 Lakhs in cumulative growth across both funds.
How to Use the STP Calculator
- Enter Source Fund Initial Balance: Input the lump sum cash parked in your liquid/debt mutual fund.
- Specify Monthly Transfer: Enter the tranche amount you wish transferred to equity each month.
- Set Source Return (%): Input expected return on the debt/liquid fund (typically 6% to 7% p.a.).
- Set Target Return (%): Input expected long-term return on the equity fund (typically 12% to 15% p.a.).
- Choose Duration: Enter the number of months for the transfer plan.
Benefits of a Systematic Transfer Plan
Rupee Cost Averaging for Lump Sums
Eliminates the fear of investing a large lump sum right before a market correction by spreading entry over multiple months.
Higher Yield on Idle Cash
Liquid and ultra-short debt funds historically yield 6%–7% p.a., significantly outperforming regular bank savings interest (2.5%–3.5%).
Automated Discipline
Avoids emotional hesitation during market volatility by executing fixed monthly transfers automatically without manual intervention.
Dual Compounding Engine
Both your source debt fund and target equity fund work simultaneously, maximizing capital efficiency across the entire tenure.
STP vs SIP vs Direct Lumpsum
Compare how STP fits into your broader asset allocation and cash deployment strategy:
| Feature | Systematic Transfer Plan (STP) | Systematic Investment Plan (SIP) | Direct Lumpsum |
|---|---|---|---|
| Source of Funds | Liquid / Debt mutual fund | Bank Savings Account | Bank Account (Single debit) |
| Yield on Idle Funds | 6.0% – 7.0% p.a. | 2.5% – 3.5% p.a. | N/A (invested immediately) |
| Best Suited For | Deploying large windfalls safely | Monthly salaried savings | Long-term cash with high risk tolerance |
| Market Timing Risk | Low (Rupee-cost averaged) | Low (Rupee-cost averaged) | High (Vulnerable to market peaks) |
Important Factors & Taxation Considerations
1. Intra-AMC Rule:In India, automated STP is only permitted between mutual fund schemes within the same fund house (AMC). You cannot STP directly from an AMC 'A' debt fund to an AMC 'B' equity fund.
2. Taxation on Source Fund Redemptions: Each monthly transfer is technically a redemption of units from the source debt fund and an investment into the target equity fund. Capital gains on debt fund units are taxed as per your applicable income tax slab rate.
3. Exit Loads: Choose a liquid fund with zero exit load after 7 days as your source scheme to avoid premature exit penalty charges.
