Calculator Inputs

Enter today’s annual figures and future assumptions. The calculator will project rising costs, income growth, savings value, and possible affordability gaps.

Enter percentages without the percent sign. Annual savings contributions are added once each year after growth for that year.

Example Data Table

Example assumptions: current annual cost 18,000, low inflation 3%, base inflation 4%, high inflation 6%, and five forecast years.

Year Low Scenario Cost Base Scenario Cost High Scenario Cost
1 18,540.00 18,720.00 19,080.00
2 19,096.20 19,468.80 20,224.80
3 19,669.09 20,247.55 21,438.29
4 20,259.16 21,057.45 22,724.59
5 20,866.93 21,899.75 24,088.06

Formula Used

1) Inflation-adjusted future cost Future Cost = Current Cost × (1 + i / m)^(m × n)

Here, i is the annual inflation rate, m is compounding periods per year, and n is forecast years.

2) Projected future income Future Income = Current Income × (1 + g)^n

Here, g is the expected annual salary growth rate.

3) Projected savings balance Future Savings = Current Savings × (1 + r)^n + Annual Contribution × [((1 + r)^n − 1) / r]

This calculator builds savings year by year. It uses r as the annual investment return rate.

4) Real return after inflation Real Return = ((1 + r) / (1 + i)) − 1

This shows whether your savings growth is actually beating inflation.

5) Safe target with buffer Safe Target = Base Future Cost × (1 + Buffer Rate)

A buffer adds extra room for uncertainty or underestimated expenses.

  3. Enter your current savings and yearly contribution amounts.
  4. Choose your base inflation rate, then set low and high scenario adjustments.
  5. Add expected salary growth and investment return assumptions.
  6. Select the forecast length and inflation compounding frequency.
  7. Use a safety buffer if you want a more conservative target.
  8. Press Calculate Forecast to show results above the form.
  9. Review the yearly table, then export the results as CSV or PDF.

FAQs

1) What does this calculator estimate?

It projects how inflation can raise an annual budget, compares low, base, and high scenarios, and shows future income, savings, purchasing power, and funding gaps.

2) Is inflation compounded in this tool?

Yes. The calculator compounds inflation using your selected frequency. Annual compounding is simple for planning, while monthly or quarterly compounding gives more detailed estimates.

3) Why are low, base, and high scenarios useful?

Inflation rarely stays constant. Scenario testing shows a reasonable range of future costs, helping you save more carefully and avoid relying on one optimistic estimate.

4) What does real return mean?

Real return measures investment growth after removing inflation. A positive value means purchasing power improves. A negative value means money grows slower than prices.

5) Does projected income guarantee affordability?

No. It is only a modeled estimate using your current income and salary growth rate. Taxes, career changes, bonuses, and emergencies can change real affordability.

6) How is future savings calculated here?

The tool grows your starting balance by the expected return rate and adds annual contributions each year. This provides a practical planning estimate for long-term goals.

7) Can I use this for retirement or education planning?

Yes. Enter the annual amount needed today, then project it forward. This works well for retirement budgets, education costs, medical spending, or family living expenses.

8) What if the low scenario becomes negative?

The calculator floors the low inflation scenario at zero. That keeps the forecast practical and avoids unrealistic negative values in everyday personal finance planning.
