Debt Freedom Formulas

Formulas to calculate debt repayment time, total interest paid, and strategies for becoming debt-free.

N = -log(1 - (P × i) / PMT) / log(1 + i)

Example:

Loan of ₹5,00,000 at 10% annual interest with monthly payment of ₹10,000

-log(1 - (5,00,000 × 0.10/12) / 10,000) / log(1 + 0.10/12)
= 60 months (5 years)

Variables:

N - Number of payments (months)
P - Principal loan amount
i - Monthly interest rate (Annual rate ÷ 12)
PMT - Fixed monthly payment

Total Interest = (Monthly Payment × Number of Payments) - Principal

Example:

Monthly payment of ₹10,000 for 60 months on a ₹5,00,000 loan

(10,000 × 60) - 5,00,000
= ₹1,00,000

Variables:

Monthly Payment - Fixed monthly payment
Number of Payments - Total number of payments
Principal - Initial loan amount

These formulas provide the mathematical foundation for the calculations. Actual results may vary based on rounding, compounding frequency, and specific lender policies.
