Savings Formulas
Future Value (Lump Sum): FV = PV × (1 + r/n)^(nt)
Future Value (PMT): FV = PMT × ((1 + r/n)^(nt) - 1) / (r/n)
Total: FV = FV(lump sum) + FV(payments)
Where PV = present value, PMT = payment, r = rate, n = periods per year, t = years

Frequently Asked Questions
How much should I save each month?
A common guideline is the 50/30/20 rule: 50% of income for needs, 30% for wants, and 20% for savings. If you earn $5,000/month, aim to save $1,000. At minimum, build a 3-6 month emergency fund first. Adjust based on your goals—saving for a house down payment might require 25-30% temporarily.
How long will it take to reach my savings goal?
Use the formula: Months = Goal ÷ Monthly Savings. For a $10,000 goal saving $500/month = 20 months (without interest). With 4% APY compounding monthly, it takes about 19 months. Our calculator factors in compound interest to give you an accurate timeline based on your savings rate and expected returns.
Where should I keep my savings?
It depends on your timeline. Emergency fund (access needed): High-yield savings account (4-5% APY). Short-term goals (1-3 years): CDs, money market accounts, or I-bonds. Long-term goals (5+ years): Consider investment accounts for potentially higher returns. Never keep large sums in checking accounts earning 0%.
What's the difference between APY and interest rate?
APY (Annual Percentage Yield) includes the effect of compound interest, showing your actual yearly earnings. A 4% interest rate compounded monthly equals about 4.07% APY. Always compare APY, not interest rates, when choosing savings accounts. A higher APY means more money earned on your savings.
How does compound interest grow my savings?
Compound interest earns interest on your interest. $10,000 at 5% APY: Year 1 = $10,500. Year 2 = $11,025 (not $11,000). Year 10 = $16,289. Year 30 = $43,219. Starting early is crucial—saving $200/month from age 25 to 65 at 7% yields $528,000, but starting at 35 yields only $244,000.
