How we calculate the savings plan
At 0% rate: monthly = (goal - current) / months. With interest we use the PMT formula or solve for n using the future value annuity formula.
Example: PLN 20,000 goal, PLN 500/month
Goal PLN 20,000, no savings yet, PLN 500/month at 3% p.a.: approx. 35 months (3 years). Total contributions: PLN 17,500, interest: PLN 2,500.
