Estimate savings balances with deposits plus interest on fixed balances at stated APY.
Overview
Cash allocation questions often come in pairs: how will ongoing savings grow, and how much does an existing balance earn over a fixed period? This combined view runs both styles of math with the APY you supply.
Keeping assumptions visible—APY, deposit schedule, term—makes it easier to compare CIT-style high-yield savings against CDs, money market funds, or debt payoff. None of those choices are purely mathematical; liquidity needs matter too.

Steps
Balance, APY, monthly deposit, years.
Optional lump-sum interest-only calculation.
See growth path and interest subtotal.
Use same APY unless tiers differ.
Record assumptions for comparison tables.
Update when bank changes APY.
Math
Savings FV with deposits; Interest = FV_lump - PV
Dual mode applies standard daily-compounded savings math for each scenario you enable.
