Inflation is the 'silent tax' on your wealth. Even at a modest 3% per year, $100,000 today will only have the purchasing power of about $55,000 in 20 years. If your savings or investments aren't growing faster than inflation, you're actually losing money in real terms. This calculator shows you exactly how inflation impacts your purchasing power over time — and whether your investments are beating it.
Real-world scenarios
Retirement Planning Reality Check
Amy, 35, estimates she needs $60,000/year in retirement at age 67. But that's in today's dollars.
At 3% inflation, $60,000 today = $158,000 in purchasing power terms in 32 years. Amy either needs to save for a $158,000/year lifestyle OR plan that her $60,000 will feel like $23,000 by the time she's 97.
Cash vs Investing
Ben has $200,000 in a savings account earning 4.5%. Inflation is 3%.
Ben's real return is only 1.5% ($3,000/year). After 20 years, his $200,000 in a savings account = $134,000 in real purchasing power. Invested at 8%, it would be worth $329,000 in today's dollars.
