This calculator converts the selected annual compounding rate into an equivalent weekly growth rate. It then updates the balance for each week across the full investment period.
Effective Weekly Rate: rw = (1 + R / m)m / 52 - 1
Weekly Balance Update: Bnew = (Bold + C) × (1 + rw) or Bold × (1 + rw) + C
Here, R is the annual rate, m is compounding periods yearly, C is the weekly contribution, and B is the investment balance. Taxes reduce the total interest, while inflation discounts the final value into today’s purchasing power.
It estimates how a weekly investment plan may grow over time. It includes starting capital, recurring deposits, interest, taxes, inflation, and contribution increases.
Weekly investing can build discipline and increase time in the market. Smaller, frequent deposits may also smooth entry prices across changing market conditions.
Compounding frequency shows how often returns are credited. More frequent compounding usually creates slightly higher growth because earnings start generating additional earnings sooner.
Inflation reduces future purchasing power. The inflation adjusted result helps you compare your projected ending balance with today’s money value more realistically.
The tool applies a tax percentage to total interest earned. This creates a net balance estimate after reducing gains by the selected tax rate.
Contributions at the beginning of the week get one extra week of growth. End of week contributions are added after interest for that week is calculated.
Yes, it can support simple retirement projections. Still, actual planning should also consider risk, fees, withdrawals, asset allocation, and changing income needs.
No, they are estimates only. Real investment returns vary over time, and markets can perform above or below your selected growth assumptions.
