Hi Support Team,
I’m using the Cost Calculator Builder plugin to create a Retirement Calculator on my WordPress website. I’ve added a custom formula to calculate the estimated retirement corpus based on inputs like current age, retirement age, current savings, monthly investment, and expected annual return.
Here’s the formula I’m using:
C * (((1 + (D / 1200)) ^ ((G - A) * 12) - 1) / (D / 1200)) + B * ((1 + (D / 1200)) ^ ((G - A) * 12))
Where:
A = Current Age
G = Retirement Age
B = Current Savings
C = Monthly Investment
D = Expected Annual Return (%)
However, the plugin output is significantly higher than the expected result. For example:
- Current Age: 30
- Retirement Age: 50
- Current Savings: ₹100,000
- Monthly Investment: ₹5,000
- Expected Return: 10%
Plugin Output: ₹16.69 Crores
It seems the formula or the field calculations are not functioning as expected. I’ve verified the formula with manual calculations, and the discrepancy persists.
Could you please help me identify:
- If the formula format is correct for the plugin?
- Whether the plugin is treating percentage or decimal values incorrectly?
- Any setting that could cause this kind of inflated output?
Looking forward to your quick assistance before purchasing the plugin.
Thanks & regards,
