Three numbers. Two ways to get back to your chosen mix: move money between equity and debt, or add new money to the underweight side without selling. Use current investment values, not the amounts you originally put in.
Shares and equity investments included in this portfolio.
Your fixed-income investments. “Debt” here means assets you hold, not loans you owe.
Use a target you have already chosen. The rest is debt / fixed income.
This is a two-bucket comparison. Keep emergency cash separate. Gold, property and other assets are not modelled.

Choose one route, or a combination. These are alternatives: do not automatically do both amounts. Values are rounded to the nearest rupee. Market movements, taxes and transaction costs are excluded.
The 60% target is an example, not a recommendation. This calculator does not submit or save the numbers you enter.
Why the two amounts are different
With ₹7 lakh in equity and ₹3 lakh in debt, a 60% equity target means ₹6 lakh of equity within the existing ₹10 lakh portfolio. Transferring ₹1 lakh from equity to debt produces ₹6 lakh and ₹4 lakh: a 60:40 mix.
If you keep all ₹7 lakh of equity, the portfolio must instead grow to ₹11.67 lakh for equity to be 60% of it. That requires about ₹1.67 lakh of new debt investment. Adding just ₹1 lakh would leave equity at 63.64%. Read Your Portfolio Has Drifted. Do You Need to Sell Anything? for the worked example.
What to include
Use current values from the same date and the same portfolio or goal. Include relevant fixed-income holdings consistently, but remember that EPF, PPF, some deposits and other holdings may be locked or costly to access. The calculator measures the mix; it does not establish that an asset can be sold today. For hybrid funds, use their underlying equity and debt portions rather than counting the whole holding in both buckets.
If you have not decided on a target, start with How Asset Allocation Keeps a Plan Balanced and the Asset Allocation Calculator. This tool restores the target you enter; it does not select one for you.
The calculation
Let E be equity, D be debt and t the target equity fraction. A transfer changes equity by t × (E + D) − E. A positive value means move money from debt to equity; a negative value means move money from equity to debt.
If equity is overweight, the new debt money required is E ÷ t − (E + D). If equity is underweight, the new equity money required is [t × (E + D) − E] ÷ (1 − t). Both formulas assume you add only to the underweight side and existing values do not move. Exact 0% or 100% targets cannot be reached with a finite top-up while the unwanted bucket still has a positive balance.
Use the result as a plan, not an automatic trade
A small drift does not necessarily justify a sale. Consider your review rule, the size of future contributions, liquidity, exit loads and tax before deciding. New money can help restore the mix, but if you add it gradually, market movements can change the amount needed. Recalculate using fresh values.
This calculator is for education, not personal investment advice or a recommendation to buy or sell a security. It models equity and debt only, at current values, before costs and taxes. A target allocation does not guarantee returns or prevent losses. For advice about your circumstances, consult a SEBI-registered investment adviser.
